Slip Compensation In V/Hz Mode; Lineare Increase; Quadratic Increase - EURA DRIVES E800 series Safety Instructions, Installation And Operating Manual

F136

Slip compensation in V/Hz mode

- 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)
F138

Lineare increase

F139

Quadratic increase

Voltage increase on low frequencies is necessary to compensate the
stator copper resistance.
With F137=0 voltage increase is chosen, suitable for constant
linear
torque load.

characteristic, like pump and fan.
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) .

Remark: V1<V2<V3<V4<V5<V6，F1<F2<F3<F4<F5<F6.
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).
WARNING!! High voltage BOOST on low speed
may result in inverter over-current trip and/or
motor overheating
