Multi-pump function (Advanced PID function)

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

1 s 0 to 100 s Set the MC switchover interlock time.
Set the time from when the MC is switched until it
1 s 0 to 100 s 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
0 to 3600 s
deceleration time for decreasing the output
1 s
frequency.
The output frequency is not decreased when a
9999
motor connection occurs.
Used to increase the output frequency of the
inverter when a motor connection occurs. Set the
0 to 3600 s
acceleration time for increasing the output
1 s
frequency.
The output frequency is not increased when a
9999
motor connection occurs.

Set the delay time until the auxiliary motor is
5 s 0 to 3600 s
started.
Set the delay time until the auxiliary motor is
5 s 0 to 3600 s
stopped.
Set the time until the auxiliary motor is stopped
0 s 0 to 900 s when the PID overpressure control function is
used.
Set the level for stopping the auxiliary motor by
0 to 100%
the PID overpressure control function.
9999
9999 The PID overpressure control function is disabled.
