NOTICE
Parameter 1-60 Low Speed Load Compen-
sation has no eect when
parameter 1-10 Motor Construction = [1]
PM, non-salient SPM.
Enter the % value to compensate voltage in
relation to load when the motor is running at
low speed and obtain the optimum U/f charac-
teristic. The motor size determines the frequency
range within which this parameter is active.

Enter the % value to compensate voltage in
relation to load when the motor is running at
high speed and obtain the optimum U/f charac-

NOTICE
Parameter 1-62 Slip Compensation has no
eect when parameter 1-10 Motor
Construction = [1] PM, non-salient SPM.
To compensate for tolerances in the value of
n
M,N
, enter the % value for slip compensation.
Slip compensation is calculated automatically,
that is based on the nominal motor speed n
M,N
.

NOTICE
Parameter 1-63 Slip Compensation
Time Constant has no eect when
parameter 1-10 Motor Construction =
[1] PM, non-salient SPM.
Enter the slip compensation reaction
speed. A high value results in slow
reaction, and a low value results in quick
reaction. If low-frequency resonance
problems occur, use a longer time setting.

NOTICE
Parameter 1-64 Resonance Damping has
no eect when parameter 1-10 Motor
Construction = [1] PM, non-salient SPM.
Enter the resonance damping value. Set
parameter 1-64 Resonance Damping and
parameter 1-65 Resonance Damping Time
Constant to help eliminate high frequency
resonance problems. To reduce resonance
oscillation, increase the value of
parameter 1-64 Resonance Damping.
