11: In VF semi separation mode, V and F are
proportional, but the proportional relation-
ship can be set through voltage source P3-15,
and the relationship between V and F is also
related to the rated voltage and rated
frequency of P1 group motor.

In order to compensate the low-frequency
torque characteristics of V / F control,
the output voltage of the AC drive at low-
frequency is increased and compensated. But
the torque lifting setting is too large,
the motor is easy to overheat, and the AC
drive is easy to overcurrent. When the
torque rise is set to 0.0, the AC drive is
the automatic torque rise. At this time,
the AC drive automatically calculates the
required torque rise value according to the
motor stator resistance and other parameters.

Torque lifting torque cut-off frequency:
under this frequency, the torque lifting
torque is effective. If the set frequency
is exceeded, the torque lifting fails.

This parameter is only valid for asynch-
ronous motor. It can compensate the motor
speed deviation when the load increases,
and keep the motor speed stable when the
load changes.

During the deceleration process of AC drive,
the overexcitation control can restrain the
rise of bus voltage and avoid over-voltage
fault. The larger the overexcitation gain,
the stronger the suppression effect.

The selection method of the gain is to
minimize the vibration under the premise
of effective suppression, so as to avoid
adverse impact on VF operation. When the
motor has no oscillation, please select the
gain as 0.
Only when the motor oscillates obviously, it
is necessary to increase the gain properly.
The larger the gain is, the more obvious the
suppression of the oscillation is. When using
the vibration suppression function, the motor
rated current and no-load current parameters
shall be accurate, otherwise the VF vibration
suppression effect is not good.
