21.8 2440 Slip comp Hz FLOAT CALCF 0.0 10.0 RWS V
Setting of the slip compensation. When the asynchronous motor is loaded, the mechanical speed of the motor
shaft varies according to the electric slippage, which affects torque generation. The slip compensation func-
tion can be used to maintain a constant motor shaft speed. Compensation is performed by varying the drive
output frequency as a function of its output current and the motor parameters. Thus, to obtain the best effect,
the motor plate data must be set appropriately, and the correct stator resistance value (Par.2050) must be set
or measured using the self-tuning function, The slip compensation value is calculated automatically during the
self-tuning procedure or set manually in this parameter.
During slip compensation tuning the drive must not be in the current limit condition.

21.9 2442 Slip comp filter ms UINT16 200 50 5000 ERW V
Setting of the slip compensation lter. The value set in this parameter determines the slip compensation func-
tion reaction time. The lower this parameter is set, the greater the slip compensation reaction. If this parameter
is too low, it could cause undesirable oscillations in speed after sudden variations to the applied load.

21.10 2444 Slip comp mode ENUM Open loop 0 1 ERW V
Setting of the slip compensation mode.
0 Open loop
1 Closed loop
When set to 0 (Open loop) the slip compensation value is that set manually in parameter 5210 or calculated by
the self-tuning procedure.
If set to 1 (Closed loop) the slip compensation value is measured by the reading of the signals by a digital
encoder keyed to the motor shaft. The EXP-DE-I1R1F1-ADV expansion card must be installed in the drive in
order to acquire encoder signals.
