V/mA
Change the display unit of the
parameters and monitored items,
which are related to PID control.
Displayed in %
Set the coefficient on bias (mini-
mum) side of terminal 4 input.
Displayed in %.
Set the converted % on bias (mini-
mum) side current /voltage of ter-
minal 4 input.
Set the coefficient on gain (maxi-
mum) side of the terminal 4 input.
Displayed in %.
Set the converted % on gain (max-
imum) side of current/voltage of
terminal 4 input.
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
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.
