"A" Group: Standard Functions
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.
