KE300A Inverter Parameter Description
145
Multi-step command can be used in two situations: as frequency source or as the setting source of the
process PID.
In two situations, the dimension of the multi-step command is relative value, range -100.0%~100.0%,
When as the frequency source is the percentage of the relative maximum frequency, multi-step command
as PID setting source does not need dimension switching, because PID given is relative value. Multi-step
command switches selection according to the different status of multifunctional digital D, please refer to P4
group for details.

0: Stop after one cycle: Inverter stops automatically as soon as it completes one cycle, and It needs run
command to start again.
1: keep last frequency after one cycle: Inverter holds frequency and direction of last phase after one cycle.
2: Circular running: Inverter continues to run cycle by cycle until receive a stop command.
