Multi-pump function (Advanced PID function)

PID control function can adjust the volume of water, etc. by controlling pumps. When the motor output is insufficient,
auxiliary motors can be driven by the commercial power supply. Up to three auxiliary motors can be connected.

No auxiliary motor operation
Set the number of auxiliary motors to be run.
Basic system
Alternative system
Direct system
Alternative direct system
Set the MC switchover interlock time.
Set the time from when the MC is switched until it starts. Set
this time a little longer than the MC switching time.
Used to decrease the output frequency of the inverter when a
motor connection occurs. Set the deceleration time for
decreasing the output frequency.
The output frequency is not decreased when a motor
connection occurs.
Used to increase the output frequency of the inverter when a
motor connection occurs. Set the acceleration time for
increasing the output frequency.
The output frequency is not increased when a motor
connection occurs.
Set the frequency to start the auxiliary motor.
Set the frequency to stop the auxiliary motor.
Set the delay time until the auxiliary motor is started.
Set the delay time until the auxiliary motor is stopped.
