MOTOR CURR. LIMIT and REGEN CURR. LIMIT
31
Calibration
The MOTOR CURR. LIMIT setting determines the maximum
current limit for accelerating and driving the motor. The REGEN
CURR. LIMIT setting determines the maximum current limit for
decelerating and stopping the motor. Both CURRENT LIMIT
trimpots are factory set at approximately 120% of maximum drive
current and must be recalibrated when using a lower current
motor.. See Figure 9, page 34, for recommended CURRENT
LIMIT trimpot settings.
To calibrate the CURRENT LIMIT trimpots:
1. With the power disconnected from the drive, connect a DC
ammeter in series with the armature.
2. Set the MOTOR CURR. LIMIT trimpot to minimum (full
CCW).
3. Lock the motor armature. Be sure that the motor is firmly
mounted.
4. Connect power to the drive. The motor should remain stopped.
Warning
Although CURRENT LIMIT is set to 120% of motor
nameplate current rating, continuous operation beyond that
rating may damage the motor. If you intend to operate
beyond the rating, contact your Minarik representative for
assistance.
