MOTOR DRIVE SET-UP

In order to provide for proper closed-loop operation, it is necessary to calibrate the motor drive maximum speed and
response adjustments according to the following procedure:

1. Adjust the lead polarity by rotating the lead encoder in the direction of normal operation while monitoring
MV-41. If MV-41 is negative, then exchange the lead encoder lines on J3 pins 3 and 5.

2. Enter a “2" into CP-14 (place M-Traverse into Direct Mode).

3. Enter a positive Direct Mode setpoint of 400 into CP-62 (Direct Analog Command).

4. Enter the RUN State (note: the F-Stop input must be shorted to common prior to activating (shorting) the RUN
input). If the follower motor direction does not match the motor direction of the lead during normal operation,
then rewire the drive/motor to reverse the motor direction.

5 . Adjust the follower polarity by rotating the follower encoder in the direction of normal operation while
monitoring MV-42. If the frequency in MV-42 is negative, then exchange the encoder lines on J3 pins 7 and 9.

6. Set the ACCEL and DECEL potentiometers on the motor drive to the minimum times (fastest response).

7. Set the I.R. Compensation potentiometer (if present) on the motor drive to its minimum setting.

8. Enter a “3686" into CP-62 (places the output command to 90% of the full 4095 level in forward direction).
A “-3686" entry into CP-62 will move in the reverse direction at 90% full output.

9. Adjust the Max Speed potentiometer on the motor drive for the desired maximum operating RPMs. This value
should be the same as the CP-19 variable entry. (The speed can be observed in MV-40 if the correct PPR value
is first entered into CP-18).

10. Return the M-Traverse to its previous mode by entering the original value into CP-14.

PROGRAMMING

This section explains how to enter the minimum set of Control Parameters required to verify system operation. Refer to
Chapter 5 of the User Manual for a discussion of the remaining parameters available to refine operation for your
explicit application.

CP-14 Control Mode

Set CP-14 to 1 for Follower/Standard Mode of operation.

CP-1 Follower Setpoint

Enter your Follower Setpoint into Setpoint 1 (CP-1). The Setpoint Select inputs A and B must be open to activate this
setpoint value.

The Follower Setpoint is the laypitch (center-to-center distance between windings on reel) entered in Engineering
Units (inches, feet, meters, etc.). The CP-15 parameter will determine the location of the decimal point for all Follower
Setpoints.
