Torque digital setting in torque control mode
Factory setting
150.0%
Setting range -200.0%
～
200.0%
Used to select the torque setting source.
The torque setting adopts a relative value, and 100.0% corresponds to the rated torque of the inverter. Setting
range-200.0%~200.0%, indicating that the maximum torque of the inverter is 2 times the rated torque of the
inverter.
When the torque setting source is selected from 1 to 7, 100% of communication, analog input, and pulse input
correspond to 17-03.

Max frequency (00-03)
It is used to set the maximum running frequency of inverter forward or reverse in torque control mode.
When the inverter torque control, if the load torque is less than the motor output torque, it will continue to rise, in
order to prevent accidents such as speeding of the mechanical system, the maximum speed of the motor during
torque control must be limited.

In the torque control mode, the difference between the motor output torque and the load torque determines the
speed change rate of the motor and the load, so the motor speed may change rapidly, causing problems such as
excessive noise or mechanical stress. By setting the torque control acceleration and deceleration time, the motor
speed can be changed gently.
However, when quick torque response is required, the torque control acceleration/deceleration time needs to be
set to 0.00s. For example, two motors are connected by a hard connection to drive the same load. In order to
ensure that the load is evenly distributed, one inverter is set as the master to adopt the speed control mode, the
other inverter is the slave and uses torque control, the actual output torque of the master As the torque command
of the slave, the torque of the slave needs to quickly follow the master at this time, then the acceleration and
deceleration time of the torque control of the slave is 0.00s.

Maximum operating frequency
Only valid for V/f control.When the V/f is running, the wave transmission mode is lower than this value for the
7-segment continuous modulation mode, and the opposite is the 5-segment intermittent modulation mode.
