Current Loop Gain
This feature gives you the ability to adjust the gain of the power amplifiers in the SD17060E to match the
electrical characteristics of your motor. The value of this parameter can range from 1 to 40 with 40 represent-
ing the largest gain increase. In general, using a larger gain will increase high speed torque but the motor will
run louder. A lower gain will offer quieter low speed operation at the cost of some high speed torque.
The use of this feature is completely optional and you can leave the Current Loop Gain at its default setting of
1 for standard motor performance.
Assuming a stable line voltage of 115 Vac, the following gains can be used for AMCI motors. These gain
settings are factory suggestions and are average settings for our motors. Your system may benefit from
increasing or decreasing these settings. In general, increase the setting by one or two counts to improve high
speed performance or decrease the settings for quieter low speed operation.
