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
The fan is normally on during
inverter operation. The fan
switches on/off according to the
temperature during a stop of the
inverter whose status is moni-
tored.
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
over voltage (E.OV ) error is
more liable to occur.
Slip compensation is not made in
the constant output range (fre-
quency range above the frequency
set in Pr. 3)
Slip compensation is made in the
constant output range.
