Multi-speed and Jog Frequency Setting
The SJ100 inverter has the capability to store and output up to 16 preset frequencies to
the motor (A_20 to A_35). As in traditional motion terminology, we call this multi-speed
profile capability. These preset frequencies are selected by means of digital inputs to the
inverter. The inverter applies the current acceleration or deceleration setting to change
from the current output frequency to the new one. The first multi-speed setting is dupli-
cated for the second motor settings (the remaining 15 multi-speeds apply only to the first
motor).
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.
