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)
