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 com-
pensation. 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 con-
stant 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
