Description
Operates at power on
Cooling fan on/off control invalid
(The cooling fan is always on at power on.)
Cooling fan on/off control valid
Used to set the rated motor slip.
No slip compensation
Used to set the response time of slip
compensation. When the value is made
smaller, response will be faster. However, as
load inertia is greater, a regenerative
overvoltage (E.OV ) error is more liable to
occur.
Slip compensation is not made in the
constant output range (frequency range
above the frequency set in Pr. 3)
Slip compensation is made in the constant
output range.
Without ground fault detection
With ground fault detection
The motor is
coasted to a stop
STF signal:
when the preset Forward rotation start
time elapses after STR signal:
Reverse rotation start
the start signal is
turned off.
The motor is
coasted to a stop STF signal:
(Pr. 250 1000) s Start signal
after the start STR signal:
signal is turned Forward/reverse signal
off.
STF signal:
Start signal
When the start
STR signal:
signal is turned
Forward/reverse signal
off, the motor
STF signal:
decelerates to
Forward rotation start
stop.
