ADP100 Series

1/4 - 5 HP Non Regenerative DC Motor Controls

General Description

The Adaptable Drive Package ADP100 Series of D.C. motor controls provides a full range of speed and torque control for 1/4 - 5 HP shunt wound and permanent magnet D.C. motors. Designed for quality and performance, these drives are targeted for the OEM and Panel Builder to meet their system requirements. Two units cover the full horsepower range. The NEMA type K single phase power bridge is precisely controlled to give the best in speed and torque regulation. Quality components, conservative heat sinking, inner current loop design, unique high frequency gating, and modular construction all combine to produce dependability, simplified installation, and competitive pricing. The Adaptable Drive Package ADP100 Series of D.C. motor controls are also offered in models for Run-Brake and Contactor Reversing operation. Six models in two physical sizes cover a horsepower range from 1/4 to 5 HP. Each model is supplied chassis-only complete with an ADP102 or ADP105 motor control installed on the option chassis. In each horsepower range, the Run-Brake models are physically interchangeable with the Contactor Reversing models.

BLAZER IV Series

1/4 - 5 HP Isolated Regen Drives

General Description

The Blazer IV Series of D.C. motor controls provide full-wave, four-quadrant regenerative speed or torque control for 1/4-5 HP shunt wound and permanent magnet D.C. motors.The BRC700 models are loaded with standard features that only Carotron could provide reliably.
One very important feature of the Blazer IV 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 an armature contactor for safety disconnect during normal stop conditions. Logic in the BLAZER IV 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 IV BRC700 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 IV 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 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.

ELITEPRO Series

5 - 60 HP Digital DC Motor Control, Regenerative and Non-Regenerative

General Description

Carotron, Inc. is proud to introduce the Elite¨Pro, the latest addition to the Carotron Family of high performance, reliable, and rugged DC motor controls. Many years of research and development by Carotron's Engineering Staff have culminated in a drive series that provides quality, accuracy, flexibility and user friendliness not found in any other drive in the market place. The heart of the Elite¨Pro is a high speed Digital Signal Processor (DSP) designed specifically for motor control applications. The speed and processing power of the DSP are further enhanced by the skillful use of five (5) additional co-processors to handle critical high speed timing functions as well as keypad and external communications. Therefore, the resulting design is very capable of handling basic control algorithms along with advanced algorithms for system functions such as PID Dancer Controls, Center Winder Controls, Tension Controls, and Customized Control Functions to meet user requirements. The power section design for the Elite¨Pro follows the same conservative design practice that CarotronŐs customers have come to appreciate in all of Carotron's designs. We provide a regenerative and non-regenerative drive chassis package that is capable of full load operation in a 55űC ambient. Compare this to our competitors that design to ambient levels of 35ű to 50űC. Standard customer interface to the Elite¨Pro is via a four-line alphanumeric, backlighted LCD display. English text and menu screens with soft-keys simplify the drive programming and eliminates the need to memorize numeric codes. A User programmable section is provided to allow frequently used monitoring screens or programming screens to be located together for specific machine functions. Two levels of password protection can be activated to prevent unwanted changes of drive parameters. RS-232 and RS-422 communications also allow interface to computers and PLC's.
