| Blazer® Series 1/4 - 5 HP
Applications:
• BLAZER
• Series 1/4 - 5 HP Isolated Drives
• General Description
• Take a closer look at the full featured BLAZER BDP400 Series by Carotron Inc. Finally, a real alternative in packaged DC drives. We have taken our standard of reliable, economical, and performance oriented D.C. drives and loaded them with an unprecedented list of standard features that make them attractive for a wide range of applications. One very important feature of the BLAZER BDP400 Series is control circuit isolation. The control circuit of each model is completely isolated from the power circuit. This isolation protects reference circuits and feedback circuits from possible damage due to accidental shorts to ground. Also this standard isolation greatly simplifies master reference, tachometer follower, and process control applications. Another primary feature is A.C. line contactors for safety disconnect during normal stop conditions. Logic in the BLAZER control circuit assures that current flow to the motor has ceased prior to de-energizing the contactors. This reduces electrical stress and increases contactor life. Encoder or pulse tachometer feedback is another key standard feature in the BLAZER BDP400 Series. This feature allows frequency signals required for process monitoring to be used to improve speed regulation and simplify system requirements. Other standard feedback methods available in each model are armature voltage or 7 and 50 VDC tachometers. An accessory drive circuit monitor, Model DCM100-000, is available to assist in set-up and troubleshooting by plugging into the control board to easily access 20 separate signals. Additional features of the BLAZER SERIES are listed on the following pages. As you can see, these units are loaded with innovative features that can simplify your drive applications.

| | | Tracker Digital Series 1/4 - 3 HP
| 
| TKR800 Series 1/4 - 3 HP Digital Motor Control
General Description:
• The Carotron TRACKER TKR800 series of motor controls provides full range, single quadrant, digital speed control of shunt wound or permanent magnet D.C. Motors. Six TKR800 models, all NEMA 4 enclosed, are available to operate motors between 1/4 and 3 horsepower. Various models are offered with options that add a process follower interface (0 - 10VDC or 4 - 20 mADC), summing input or trim pot interface. The TKR802 models are customer connectable for operation at 115 VAC or 230 VAC single phase input. When operated at 115VAC input, each unit supplies variable armature voltage up to 90 VDC and a fixed field voltage of 100 VDC. For operation at 230 VAC input, each model supplies up to 180 VDC for armature voltage and a fixed field supply of 200 VDC. The TKR803 models are customer connectable for 230 VAC input operation only and has outputs of up to 180 VDC for the armature voltage and 200 VDC for the field voltage. The TRACKER can be programmed to operate as a Master or Follower. In Master Mode, the TRACKER uses actual motor speed (Feedback Input) and a digital setpoint input by the user to precisely control the speed of the motor. The digital loop of the TRACKER operates on a 10 ms control cycle which feeds into an analog velocity loop. Actual motor speed is read and the drive speed is corrected first by the inner velocity loop. The motor speed is then fine tuned to the digital setpoint by the outer digital control loop. The Digital Output Value (which is fed into the analog velocity loop) is made up of two parts: the Open Loop term, and the correction term or Trim Value. The open loop term is the ratio of the Reference Speed to Maximum Speed. This is the uncorrected Feed Forward part of the Output Value. The Reference Speed is the current Speed setpoint taking into account any acceleration or deceleration which may be in progress. The Maximum Speed is Max RPM Feedback which is set when scaling the unit. The correction term or Trim Value is derived from actual motor speed (Encoder Feedback Input) and the Reference Speed. The Trim Value is added to the Open Loop term when the Tracker is running Closed Loop to provide precise control. The Error Gain determines the rate at which the Trim Value changes in response to a motor loading or a sudden speed change. The Trim Value is updated every 10ms. It may be viewed as one of the programmable display options. In Follower Mode, the basic operation is the same except that the Reference Speed is generated as a ratio to the Lead Input speed.

Standard Features:
• 2 Wire or 3 Wire Forward/Stop/Reverse logic
• Standard PID software
• Standard energy savings software
• Built in DC link choke for 30 - 250 HP
• Low noise up to 550 HP

• 2 second power loss ride-through
• 2 jump frequencies with bandwidth adjustment
• DC injection braking at start and stop
• Input and output phase loss detection
• RS-232C serial communication port with Modbus protocol
Features:
• PID Control
• The VP5 with standard PID (Proportional-Integral-Derivative) provides true constant flow control for fan and pump applications. Many competitive products offer only P and I control. Offset and feed forward are easy to program and setup. Feedback inversion programmable.
• Unique Energy Savings
• Built-in Energy Savings software in the VP5 automatically reduces the output voltage to the motor during light load conditions. This allows the system to operate at its optimum efficiency. The drive is constantly performing real-time automatic tuning to adjust the voltage even to compensate for temperature variations. The secret is in the unique high speed algorithm that allows for the fast response time to any load fluctuation.
• Low Noise Operations
• Most manufacturers of PWM drives have made the conversion to IGBT's (Insulated Gate Bi-Polar Transistors) in the inverter section. This allows for higher carrier frequencies which reduce the motor acoustical noise. Only the VP5 through its unique asynchronous carrier frequency technique, ASIPM (Application Specific Intelligent Power Module) and third generation IGBT's allows a motor noise level equal to across-the-line operation.
• Standard DC Link Choke
• Many customer specifications are calling for input AC line reactors. The VP5 has a built-in DC link choke as standard from 30 - 250 HP or available as an external option from 0.75 - 25 HP. This DC link choke provides the same protection and harmonic compensation as a 3% impedance input reactor.
• 12-Pulse Input
• In addition to the DC link choke described above, an optional input phase shifting transformer will provide a near sinusoidal input current waveshape. The 30 - 250 HP VP5 units have the necessary 12-pulse dual diode converter section built-in as standard. This option will typically be sufficient to reduce the total current harmonic distortion to below IEEE 519-1992 levels.
• Reliable Operation
• Built-in functions for current limit provide protection during acceleraion and during run conditions. Deceleration over-ride extends stopping time to prevent nuisance overvoltage trips. Speed search allows the drive to be started into a rotating motor without excessive current or tripping.

| Vista® VG5 Series Flux Vectors 3/4 - 500 HP
Standard Features:
• 4 modes of operation

• Fast response to changes in torque and speed commands
• Servo-like performance with a general purpose AC induction motor.
• High starting torque
• Removes the last perception that DC or brushless DC is the best drive for applications like extruders.
• Fuzzy logic accel/decel
• Optimized starting and stopping times.
• Built-in DC link choke (30-250 HP standard, 0.75-25HP external option)
• Provides same system protection and line harmonics compensation as input 3% impedance AC line reactor.
• Low noise operation through 500 HP
• Motor acoustical noise will not exceed across-the-line operation.
• Large software library
• Proven field experience in all applications.
• Fault trace
• Snap shot of 11vital drive characteristics at time of fault for ease of troubleshooting.
• Auto-tuning by motor nameplate values
• Simplified method to achieve optimal motor/drive system performance.
• Torque Control
• High starting torque and fast response time in the VG5 are assured by means of a full-scale flux vector current control. This directly controls the motor torque based on a control algorithm that utilizes a magnetic flux observer and fuzzy logic. In the open loop flux vector mode, the speed control range is 100: 1 with speed regulation of ± 0.2% from 0 to 100% load. For tighter control, the closed loop flux vector mode provides a speed control range of 1000: 1 with speed regulation of ± 0.02% from 0 to 100% load.
• 4 Quadrant Torque Limit
• A change in the load command from 0 to 180% results in almost no change in motor speed and tripless operation by use of true 4-quadrant torque limit control. Four-quadrant torque limit control can be used to limit regeneration on high inertia loads.
• Speed Response
• Changes in the motor speed command require an increase in the torque command to perform the necessary acceleration or deceleration. The VG5 can respond to a 50RPM step change in approximately 50mS. This VG5 servo-like performance is achieved through a unique fuzzy logic algorithm that optimizes the acceleration (C 1-01 ) and deceleration (C 1-02) times dependent on load conditions.
• Torque Response
• Fluctuations in the torque command are handled as easily as the changes to the load command and speed command. Again, the VG5 near servo-like performance is realized with a standard AC induction motor.
• Speed/Torque Control Changeover While Running
• The VG5 has the unique ability to operate in speed control or torque control and toggle back and forth through the use of one of the six multi-function digital inputs.

• Communications
• Many users and OEMs have already recognized the benefits of serial communications with motor controllers. The lower cost of engineering and installation combined with enhanced flexibility make this an attractive low cost alternative to control wiring. Many products offer serial communications only as an option. The V7A comes with RS-485/422 capability right out of the box. No need to worry about special connectors or cables because the wiring is done directly on the terminal strip.
• Keypad with Memory
• The V7A offers many sophisticated functions not normally available in other micro-inverters. For example, the keypad can be used as a "copy unit" to conveniently download parameters into multiple drives. It uses Flash ROM to support custom software via an RS-232 port. The keypad can be remote wired with a simple telephone cable. The cooling fan can be set to run only during inverter operation to maximize MTBF. These are but a few examples that differentiate the V7A.

• Model D10541-000 Dancer Position Card, also referred to as a P.I.D. control, is designed for applications where dancer positioning is used to maintain control of motorized operations. This card is also suitable for most any type of P.I.D. control application. The electronic circuitry utilizes the Proportional, Integral, and Derivative functions to condition the output. Each function can be adjusted independently to control the amount of change in the output voltage. The output of the proportional circuit is a voltage level proportional to the dancer and position inputs. The output of the integral is dependent upon the reference applied to a 12 bit digital analog converter. The converter allows the circuit to ratio the reference input and provide a percentage of the reference as output. An isloated scaling circuit allows optional external voltage scaling of the integral circuit to condition for diameter or velocity changes. The derivative circuit adds to the output during changes in the dancer input. The response and level of the derivative function are independently adjustable to allow for flexible and stable operation. The output of the proportional, integral, and derivative are summed together to formulate the final output. This output can be further modified by an output range potentiometer. A summing input is provided to allow an
• external voltage to be summed directly with the output. A selection is supplied to change the function, addition or subtraction, of the summing input
• as required. Positive, negative, and bipolar connection terminals are also available for use.

| 22 - 2200 LB. Capacity Load Cells 22-2200 Lb. Capacity
General Description :
• The LCS01 Series of load cells uses LVDT type sensor to convert tension into a proportional electrical signal. The LVTD system provides precise, accurate tension measurement while the mechanical design allows for extremely high overloads without damage to the unit. As web tension increases, the resultant force F also increases. This causes the load plate to rotate minutely around the pivot point 0. This 0 point is a torsion
• bar which resists the force F. Due to leverage advantage, actual sensing roll movement is quite small. Movement of the core in the LVDT is proportionately
• larger. As the core moves within the LVDT coil, the output of the coil varies directly with the core movement, which varies directly with the force F.
• The output is thus proportional to F. The mechanical structure of the torsion bar and the mechanical limit stops on the load plate allow the LCS01
• Sensors to survive 100-to-1 overloads without structural failure or variance in calibration. The LVDT housing also contains a high-frequency oscillator
• circuit which guarantees excellent linearity. Also a thermal compensating circuit ensures zero thermal drift when used within the stated temperature range.

| Voltage To Pressure Transducers Model PTEE01-XXX
General Description:
• The Carotron Voltage to Pressure Transducer, Model PTEE01, accepts an electrical input signal, 0-10VDC, and converts it to a proportional output pressure. Model PTEE01 is a single loop unit consisting of valves, manifold, internal pressure transducer, and electronic controls. Pressure is controlled by two solenoid valves. One valve functions as inlet control, the other as exhaust. The pressure output is measured by a pressure transducer internal to the PTEE01 which provides a feedback signal to the electronic controls. This feedback signal is compared against the command signal input. A difference between the two signals causes one of the solenoid valves to open, allowing flow in or out of the system. Accurate pressure is maintained by controlling these two valves. Each unit also comes standard with a monitor output that can be used with a meter or data acquisition needs. The 0-10VDC signal is from the internal pressure transducer. Available accessories include a 15VDC, 300mA power supply and mounting bracket.

| Current Sensing Board Model C10748-XXX
General Description:
• Quality Design
• Model C10748-XXX Current Sensing Board is a means of sensing AC and DC Current while providing isolation. There is a minimum of 1500 Vrms isolation between the sensed conductor and the card output. This unit is intended for use in systems to measure current in DC motors and line operated AC motors. It is also able to measure motor current out of Electronic Soft Starters. In this case the current range must be considered and the start current must stay in the range of this unit. It is not intended to measure output current from AC Variable Frequency Drives. When the unit is used to measure DC, it's output can have the same polarity as the current or it can have positive only output to indicate absolute level. The scaling is adjustable up to 10 volts full scale. The Bipolar Output matches the waveform of an AC signal within it's risetime limitation. The Unipolar output is rectified and filtered so only a DC voltage is available indicating the level of the current. When the unit is used for single phase applications, the bipolar output is to be 4 volts or less to avoid saturation due to the form factor of the current. The current range can exceed 600 amps depending on the current waveform and can handle a maximum of less than 10 amps by using multiple turns through the sensor. Calibration of the unit is dependent on use of an accurate shunt and voltmeter or ammeter to set the scaling.
