8) Parameter group 100: Basic parameters
F136
Slip compensation in V/Hz mode
Range: 0 - 10%
Default setting: 0
- This parameter compensates the load-depending slip of the asynchronus motor – it works only in the stable area of the motor
speed/torque characteristic
- during the "catch on the fly" process this function is deactivated
F137
Motor voltage increase in the
low frequency range (for V/Hz
mode only)
Selection: 0:
Linear
1:
Quadratic
2:
User defined (6 - Point)
3: Automatic
Default setting: 3
F138
Lineare increase
Range:
1 - 20
Werk: 0.2-3.7 kW : 7
5.5-30 kW : 6
37-75 kW : 5
> 90 kW: 3
F139
Quadratic increase
Selection:
1 - 6
Default
setting:
1
Voltage increase on low frequencies is necessary to compensate the
stator copper resistance.
With
F137=0
linear
voltage increase is chosen, suitable for constant
torque load.

F137=2,
serves to possible to program a user specific V/Hz curve – see table below
A total of 12 parameter are necessary to define the user specific curve
(F140 bis F151)

If
F137=3,
the slip compensation works in automatic – correct setting
for all motor parameter is necessary to guarantee correct operation –
AUTOTUNING may be used to find motor parameters, like
inductance and stator resistance (see parameter group 8).
