given torque is negative.
When the torque setting adopts mode 1 to 5, the 100% of communications, analog input
and pulse input corresponds to FA.02.
FA.03
Torque control acceleration time

FA.04
Torque control deceleration time
0.00s to 650.00s
0.00s
☆
Under the torque control mode, the difference between the motor output torque and load
torque determines the change rate in speed of the motor and load, therefore, the motor speed
may rapidly change, resulting in the problems such as noise or excessive mechanical stress. By
setting the torque control ac/deceleration time, you can make a smooth change of motor speed.
But the occasions that needs the rapid response of torque, the torque control
ac/deceleration time must be set to 0.00s. For example: when two hardwired motors drag the
same one load, in order to ensure that the load is evenly distributed, you must set one inverter as
the master unit that works under the speed control mode, the other inverter as the auxiliary unit
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.

☆
The setting overvoltage point of the software has no influence on the setting overvoltage
point of the hardware.The value of the voltage setted to the frequency inverter, different voltage
level’s factory defaults are as following:
Voltage level
Overvoltage point factory defaults
Single phase 220V
400.0V
Three phase 220V
400.0V
Three phase 380V
810.0V
Remark: Meanwhile, the factory defaults are the upper limit value of overvoltage
protectation in frequency inverter. Only when Fb.02 setting value is smaller than all voltage
