MDC Manual 1109KB - Red Lion Controls

QUICK START - SETTING UP THE MDC
While it is generally recommended that you read this instruction manual
thoroughly before attempting to set up and operate the model MDC Motor
Drive Controller, the following quick set-up procedure provides the basic
steps to get the MDC up and running.
1. Read “General Description” and “Block Diagram” to familiarize yourself
with the Basic Connections. (A/C, Inputs, Outputs, etc).
2. Wire or set the Control Inputs to their proper states:
- RUN may be left open for front panel control, or wired to common
through a momentary, normally OPEN switch for remote
operation.
- R-STOP may be tied to common for front panel control, or wired to
common through a momentary, normally CLOSED switch for
remote operation.
- F-STOP must be tied to common or wired to common through a
momentary, normally CLOSED switch.
- JOG must be left open or wired to a momentary, normally OPEN switch
requiring a sustained closure for Jog mode.
- OPEN LOOP must be left open for normal closed loop control, or wired
to a switch which can be maintained in the open or closed position,
depending on User preference.
Refer to “Dedicated Control Function and User Inputs” in the “Installation
and Connections” section for more information.
3. Set the AC power selection switch and connect AC to the MDC as noted in
“AC Power Wiring” in the “Installation and Connections” section.
4. Review “Programming General Description” and “Keypad Description” to
familiarize yourself with the Front Panel Programming procedure.
5. To set up the MDC for Master Mode - Program the scaling variables for
PPR FB, MAX RPM FB, DSP DP, and DSP UNIT. Refer to the “Program
Scaling Menu”.
6. To set up the MDC for Follower Mode - Select Follower Mode in the
Operating Mode Selection Menu. Program the scaling variables for PPR
FB, MAX RPM FB, DSP DP, and DSP UNIT. Refer to “Program Scaling
Menu”. Pay particular attention to “Additional Scale Factors in Follower
Mode”. This will explain the two additional required variables PPR LD and
-5-
RPM LD, which are part of setting the Unity Ratio. Understanding the
Unity Ratio is crucial to scaling in Follower Mode.
7. Refer to “Isolated Drive Output Calibration” section to determine if the
MDC Drive Output span needs to be calibrated. Most applications require
calibration of the drive only. Calibrate the drive as noted in “Motor Drive
Setup”.
8. Disconnect AC power. Wire the MDC to the motor drive. Refer to “Wiring
from MDC to Motor Drive” in the “Installation and Connections” section.
9. Wire the FEEDBACK and LEAD (follower mode only) frequency inputs.
Set the DIP Switches as required. Refer to the “Installation and
Connections” section.
10. Apply power to the MDC and Drive.
11. To run the motor, connect the RUN Input to common momentarily or
press the F1\RUN key, located on the Front Panel. The MDC will run the
motor to the selected setpoint using the currently selected ramp rate. If the
setpoint is changed during Run Mode using the Front Panel Keypad or a
remote input, the MDC will either accelerate or decelerate the motor to the
new setpoint using the current ramp rate.
12. To stop the motor, momentarily disconnect the R-Stop Input from
common or press the “F2/STP” key, located on the Front Panel. The MDC
will decelerate the motor using the currently selected ramp rate.
13. Disconnecting F-Stop momentarily from common will cause the MDC to
take the Drive Output voltage immediately to zero volts. This will cause
the motor to execute a Fast Stop uncontrolled by the ramp rate. If the
F-Stop Input remains open from common, the Run and Jog inputs are
disabled and the Drive Output voltage is fixed at zero volts. A maintained
switch should be used on the F-Stop input if this type of lock out is desired.
