113 Load compensation at low speed
(LO SPD LOAD COMP)
Value:
0 - 300 %
Function:
This parameter enables compensation of voltage in
relation to load when the motor is running at low speed.
Description of choice:
Optimum U/f characteristics are obtained, i.e.
compensation for the load at low speed. The frequency
range within which Load compensation at low speed
is active, depends on the motor size.
This function is active for:
Motor size
0.5 kW - 7.5 kW
11 kW - 45 kW
55 kW - 355 kW
114 Load compensation at high speed
(HI SPD LOAD COMP)
Value:
0 - 300 %
Function:
This parameter enables compensation of voltage in
relation to load when the motor is running at high speed.
Description of choice:
In Load compensation at high speed it is possible
to compensate for the load from the frequency
where Load compensation at low speed stopped
working to max. frequency.
This function is active for:
= factory setting. () = display text [] = value for use in communication via serial communication port

115 Slip compensation
(SLIP COMPENSAT.)
Value:
-500 - 500 %
Function:
Slip compensation is calculated automatically, i.e. on
the basis of the rated motor speed n
In parameter 115, slip compensation can be
adjusted in detail, which compensates for
tolerances in the value of n
This function is not active together with Variable
torque (parameter 101 - variable torque graphs),
Torque control, Speed feedback and Special
motor characteristics.
Description of choice:
Enter a %-value of the rated motor frequency
(parameter 104).
116 Slip compensation time constant
(SLIP TIME CONST.)
Value:
0.05 - 5.00 sec.
Function:
This parameter determines the slip compensation
reaction speed.
Description of choice:
A high value results in slow reaction. Conversely,
a low value results in quick reaction.
If low-frequency resonance problems are encountered,
the time set must be longer.
