  • Page 1 THE MOTOR DRIVE CONTROLLER MODEL MDC INSTRUCTION MANUAL...
  • Page 2 INTRODUCTION The Motor Drive Controller (MDC) is another unit in our multi-purpose series of industrial control products that is field-programmable for solving various applications. This series of products is built around the concept that the end user has the capability to program different indication and control requirements.

  • Page 9: D) Theory Of Operation

    In Master Mode, the MDC uses actual motor speed (Feedback Input) and an analog control voltage (Drive Output) to precisely control the motor’s speed. The MDC operates on a 10 msec control cycle. Actual motor speed is read and drive output is corrected every 10 msec. The Drive Output voltage is generated by a 12 bit DAC (digital to analog converter).

  • Page 10: E) Normal Operating Mode

    NORMAL OPERATING MODE When the MDC is powered up, it is in the Normal Operating Mode with the Indication Display Module viewed. The up and down arrow keys are used to scroll through the Indication Displays. The Indication Displays are referenced as 1 to 4 with the factory default settings of 1 (SPEED), 2 (OPERATING STATUS), 3 (ALARM STATUS), and 4 (TRIM).

    “FB FREQ OVERFLOW”, or “LD FREQ OVERFLOW” when the respective input frequency exceeds specifications. A second type of overflow is an Indication Display overflow. The MDC flashes the word “OVERFLOW” in the appropriate display when the overflow condition occurs. A display overflow occurs if the capacity of the display is exceeded.

  • Page 23: Setpoint Increment

    The jog function only operates from the STOP mode. Pressing and holding a function key selected for JOG causes the MDC to accelerate the motor to the jog speed setpoint using the jog ramp rate. The motor remains at the jog speed until the function key is released, at which point the MDC executes an F-STOP.

    PROGRAM ALARMS MENU Alarm parameters 1 and 2 activate solid state Alarm Outputs 1 and 2 respectively. A manual reset, which requires the use of a User Input, will reset an Alarm Output (see Program User Menu). Both alarms may be programmed for any of the five alarm functions: High Alarm, Low Alarm, Deviation Alarm, Zero Speed Alarm, and Disabled.
