134 Start compensation
(START COMP.)
Settings:
0.0 - 300.0 %
[0-3000]
✭
100.0 %
[1000]
Function:
The output voltage is compensated as a function of
the load.

NB!
If the value is too high the FC motor can trip
due to overcurrent.
Description of choice:
Enter a % value.
Rated start compensation = 100 %.
135 U/f ratio (U/F RATIO)
Settings:
0.00 - 20.00 V/Hz
[0-2000]
✭
Motor dependent
Function:
The output voltage to the motor can be adjusted on
a linear basis from 0 to rated frequency.
136 Slip compensation
(SLIP COMP.)
Settings:
-500.0 - +500.0 %
[-5000 - +5000]
✭
100.0 %
[1000]
Function:
The rated slip compensation (factory setting) is
calculated on the basis of the motor parameters.
In parameter 136 the slip compensation can be
adjusted in detail. Optimizing makes the motor
speed less load dependent. This function is not
active at the same time as variable torque
(parameter 101).
Description of choice:
Enter a % value of rated slip compensation.
137 DC holding voltage
(DC HOLD VOLTAGE)
Settings:
0 - 100 %
[0-100]
✭
0 (OFF) %
[0]
Function:
This parameter is used to uphold the motor function
(holding torque) or to pre-heat the motor. DC holding
voltage is active at stopped motor when it is set at a
value which is different from 0. Coasting stop will
deactivate the function.
Description of choice:
Enter a percentage value.
138 Brake cut out frequency
(BRAKE CUT OUT)
Settings:
0.5 - 132 Hz (parameter 200)
[5-]
✭
3.0 Hz
[30]
Function:
Here the frequency at which the external brake is to
be released is selected via output set in parameter
340 during running.
Description of choice:
Set desired frequency.
