Adjust the output torque (current) of the motor
Starting torque adjustment
On the assumption that Pr. 19 "Base frequency voltage" is 100%, set the output voltage at 0Hz
in % to Pr. 0 (Pr. 46).

CAUTION:
Adjust the parameter little by little (about 0.5%), and check the motor status each time.
If the setting is too large, the motor will overheat. The guideline is about 10% at the
greatest.
The requirements of the motor manufacturer must also be observed.
Set multiple base frequencies (RT signal, Pr. 46)
Use the second torque boost when changing the torque boost according to application or when
using multiple motors by switching between them by one inverter.
Pr. 46 "Second torque boost" is made valid when the RT signal turns on. The RT signal acts as
the second function selection signal and makes the other second functions valid.
