Drive Calibration Procedure

Prepare the DC3N drive for calibration as follows. This

procedure applies to both chassis and enclosed drives.

1. Ensure that no power is applied to the drive.

2. If you use an enclosed drive, you must open the drive

cover to gain access to the trimpots. Turn the slotted

screw on the front cover counterclockwise until it is

free from the enclosure. The right side of the cover is

hinged to the enclosure. Pull the slotted screw to open

the enclosure.

3. Set all trimpots except CURRENT LIMIT and TACH

VOLTS full counterclockwise (CCW).

4. Set the CURRENT LIMIT trimpot full clockwise

(CW).

5. Make no adjustment to the TACH VOLTS trimpot

unless tachometer feedback is used. If you use

tachometer feedback, set the TACH VOLTS trimpot

to the center of travel (12 o’clock position).

6. Adjust the trimpots in the following order:

• MIN SPD

• MAX SPD

• CURRENT LIMIT

• IR COMP

• ACCEL

• DECEL

• TACH VOLTS (if used)
