12.6 CURRENT LIMIT TRIMPOT (CL)
Motor Overload (I
2
t) with RMS Current Limit (CL) sets the current limit (overload),
which limits the maximum current to the motor, prevents motor burnout, and
eliminates nuisance trips. In order to ensure that the motor is properly protected with
the I
2
t feature, it is required that the CL Trimpot be set for 160% of the motor
nameplate rating.
The CL Trimpot is factory set to 160% of the drive’s Maximum Continuous Load
Current rating. To increase the current limit, rotate the CL Trimpot clockwise. To
decrease the current limit, rotate the CL Trimpot counterclockwise. See Figures
22 – 26.
Note:
During normal operation, if the ST LED illuminates red, the CL Trimpot may be
set too low or the motor may be overloaded. Either increase the CL Trimpot setting or
monitor the motor current to adjust the CL Trimpot for the proper setting.
