Drive Parameters

 

 

The L100 inverter has the capability to store and output up to 16 frequencies to the motor (A20 to A35). As in traditional motion terminology, we call this multi-speed profile capability. Binary-encoded logic inputs select the particular frequency (speed) setting, and the inverter applies the current acceleration or deceleration setting required to change from the current output frequency to the new one.

The jog speed setting is used whenever the Jog command is active. The jog speed setting range is arbitrarily limited to 10 Hz, to provide safety during manual operation. The acceleration to the jog frequency is instantaneous, but you can choose from three modes for the best method for stopping the jog operation.
