that works under the torque control mode, the Actual output torque of the master unit is used as the
torque command of the auxiliary, the torque of the auxiliary needs quickly follow the master unit,
so the torque control ac/deceleration time of the auxiliary unit shall be set to 0.00s.

Used to set the maximum operating frequency of inverter forward or reverse running under
the torque control mode
Under the torque control mode, if the load torque is less than the motor output torque, the
motor speed will continue to rise, in order to prevent "Runaway" and other accidents of
mechanical systems, it is necessary to limit the maximum speed of motor under the torque control
mode.

Enable Quick Current Limiting function, which can minimize the overcurrent fault of
inverter , and ensure the uninterrupted operation of inverter. If the drive is in the state of fast
current limiting for a long period of time , the inverter may be damaged by overheating and others,
this case is not allowed, so the inverter will alarm fault with fault ID Err.40, it indicates that the
inverter exists overload and needs to be shut down.

Used to set the voltage value of inverter undervoltage fault with fault ID Err.09 , the different
voltage levels of inverter 100.0% corresponds to the different voltage points are as follows:
Single-phase 220V or three-phase 220V: 200V three-phase 380V: 350V
Three-phase 480V: 450V three-phase 690V: 650V

The setting over voltage point of the software has no influence on the setting over voltage
point of the hardware. The value of the voltage set to the frequency inverter, different voltage level
„s factory defaults are as following:
Voltage level

Single phase

400.0V
Three phase

Remark: Meanwhile, the factory defaults are the upper limit value of over voltage protection
in frequency inverter. Only when Fb.02 setting value is smaller than all voltage factory defaults,
the new parameter setting takes effect. If it is higher than factory defaults, factory defaults will be
the standard value.

Generally do not need to modify this parameter, only when the special requirements to the
output voltage waveform quality is required or when the motor oscillation and other abnormal
happen, you need to try to switch to select a different mode of compensation.The compensation
mode 2 for high-power is recommended.
