DESCRIPTION

The Motor Drive Controller (MDC) regulates motor speed by varying an

isolated DC control signal to a motor drive system. There are two modes of

operation, Master and Follower.

Master Mode provides control of a motor directly via programmed speed

setpoints in the MDC. Regulation is maintained by a feedback frequency to the

MDC taken from the motor shaft or a downstream shaft pulse encoder. Follower

Mode controls a motor’s speed as a ratio to a second motor’s speed or outside

frequency source. Ratio setpoints are programmed into the MDC causing the

motor to “follow” the lead motor or frequency at a fixed speed ratio.

Master Mode has two speed setpoints and two ramp setpoints. Follower

Mode has two ratio setpoints and two ramp setpoints. Both modes share a jog

speed setpoint and a jog ramp setpoint. All setpoints are retained in non-volatile

memory when the unit is powered down.

The Motor Drive Controller has the added feature of allowing real time

adjustment of the Speed (Master Mode) or Ratio (Follower Mode) setpoint

while the unit is operating a motor drive system. The setpoint may be adjusted

via the front panel keypad using the “Up” or “Down” arrow keys, or via 2 User

Inputs programmed for increment setpoint and decrement setpoint.

User flexibility is provided through the two-line by eight-character

alphanumeric display. The display features English language menus for easy

viewing and simplified programming. The four scroll-through indication

displays can be programmed to show various parameters and to automatically

scroll, if desired. A program disable DIP switch used with an external User Input

can be utilized to protect the settings and guarantee that no unwanted changes

occur during operation.

There are five dedicated control inputs on the MDC:

RUN

RAMP STOP

FAST STOP

JOG

OPEN LOOP

There are six programmable control inputs: two front panel function keys and

four remote user inputs. The F1 and F2 keys are factory programmed for RUN

and R-STOP respectively. This eliminates the need for external switches in

some applications.

There are three solid state outputs, two are programmable alarms and one is

a dedicated Drive Enable output. Programmable alarm functions include:

High Alarm

Low Alarm

Deviation Alarm

Zero Speed

Disabled

These may be programmed for boundary or latching operation, high or low

acting.

Changing speed setpoints and programming information is easily

accomplished by scrolling through menus and selecting the correct parameter.

There are three main modules or menu loops:

Display Module

User Setpoint Module

Programming Module

Scaling is accomplished by entering the desired values for feedback pulses

per revolution (PPR), the maximum RPM, and the maximum display value.
