The multi-stage command can be used as frequency source, can also act as the set source of
process PID. The dimension of multi-stage command is the relative values and its range is from -
100.0% to 100.0%, when it acts as the frequency source, it is the percentage of maximum
frequency; due to the PID reference is originally as a relative value, therefore the multi-stage
command acts as the set source of PID and does not need dimension conversion.
The multi-stage command needs to switch according to the different states of multifunction
digital DI, please refer to F1 group for specific instructions.
stop after single running
hold final value after single running
The figure is the schematic diagram of Simple PLC as the frequency source. For Simple PLC
as the frequency source, the positive or negative value of E1.00 to E1.15 determines the running
direction, the negative value indicates that the inverter runs at the opposite direction.
As the frequency source, PLC operates in three modes, including:
0: stop after single running
After the inverter completes a single cycle, it will automatically shut down , the running
command must be given before restart.
1: hold final value after single running
After the inverter completes a single cycle, it will automatically maintain the frequency and
direction of the last stage.
2: circulating
After the inverter completes a cycle, it will automatically start next cycle, and stop till the
stop command is given.
