The SJ300 inverter has the capability to store and output up to 16 preset frequencies to the
motor (A020 to A035). 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 duplicated 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 six modes for the best method for
stopping the jog operation.
