MD021 Plastic Wire Drawing Machine User Manual
Set the parameters based on the parameters on the nameplate of
the motor.
To guarantee the control performance, choose the standard
adaptive motor of the inverter. If a great difference exists
between the actual motor power and the adaptive motor power,
the control performance of the inverter may degrade.

To compensate the low frequency torque characteristics of V/F control,
you can boost the output voltage of the inverter at low frequency.
"Torque boost" (F0-10) is set to a certain percentage of the input rated
voltage of the inverter. The setting is as follows:
When this parameter is set to 0.0%, automatic torque boost is applied
for the inverter.
Set this parameter to a larger value for a low-power motor and to a
smaller value for a high-power motor.
If this parameter is set to a too large value, the motor may easily be
overheated and the inverter may suffer over-current.
