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.

DIMENSIONS In inches (mm)

Note: Recommended minimum clearance (behind the panel) for

mounting clip installation is 3.0" (76.2) H x 4.0" (101.6) W.

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.

DESCRIPTION (Cont’d)

The unit is factory configured for an isolated 0 to 10 VDC drive output signal. The output drive signal can be adjusted to span from 0 to 15 VDC via an accessible potentiometer. The drive output is jumper selectable for an external reference. To use the external reference, the MDC is connected to the drive in place of an external potentiometer.

The Motor Drive Controller has a light weight, high impact plastic case with a clear viewing window. The sealed front panel meets NEMA 4X/IP65 specifications for wash-down and/or dusty environments, when properly installed. Plug-in style terminal blocks simplify installation and wiring change-outs.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the manual or on equipment must be observed to ensure personal safety and to prevent damage to either the instrument or equipment connected to it. If equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

Do not use this unit to directly command motors, valves, or other actuators not equipped with safeguards. To do so, can be potentially harmful to persons or equipment in the event of a fault to the unit.

CAUTION: Risk of Danger.

Read complete instructions prior to

installation and operation of the unit.

CAUTION: Risk of electric shock.

PROGRAMMING

Programming the MDC unit is accomplished through the front panel keypad,

which allows the user to enter into Main Menus, Sub-Menus, and Edit Menus. The English language prompts, the flashing parameter values, and the front panel keypad aid the operator during programming. In the normal run mode, the main display loop allows the user to scroll through the four programmable indication displays, using the direction keys. From the main loop, setpoints, alarm values and a gain value may be accessed directly for changes, without entering the programming loop. All other parameters are accessed through the pro-gramming loop, which can be set to require an access code number for loop entry. In the programming loop, parameters can be viewed or changed and the operator can exit anywhere in the loop.
