Motor polling cycle
0.0–6000.0h
Automatic polling is targeted at idle
variable-frequency motors. The value 0
indicates no polling.
0.0h

P94.35
Running frequency
threshold for polling
P00.05–P00.03
When the running frequency is greater than the
value of this function code, variable-frequency
motor polling is not performed. Otherwise, great
water pressure change impacts water supply.
45.00Hz

P94.36
Contactor closing
delay
0.2–100.0s
The delay starts after the contactor closing
command is given. The VFD startup command
is given after the delay since actual contactor
closing also takes some time.
0.5s
○
P94.37
Contactor opening
delay
0.2–100.0s
Some time is taken from giving the contactor
opening command to actual contactor opening.
After the delay, the VFD controls the motor to
switch to power frequency.
0.5s

P94.38
Manual soft startup
