When AI is used as the frequency setting, voltage/current input correspond to 100.0% of the setting.It refers to
the percentage of relative torque digital setting PF-02.The input voltage values of AI and the corresponding
relationship curve with the target torque can be freely selected by the user through P2-54.
VH6 provides five groups corresponding relationship curves, among which three groups of curves are linear
relationships (2-point corresponding relationship), and two groups of curves are broken lines with 4-point
corresponding relationship. Users can set them through Group P2 parameter.
5: Communication setting
The target torque is given by the communication mode.
When MODBUS is used for communication, the data is given by the host computer through the communication
address H1000, and the data format is data with 2 decimal places.
For reverse operation, users can set PF-02 as the negative value or write a negative value into H1000.
Note: in 3730 and above versions
When MODBUS is used for communication, the data is given through the communication address H1105,
which refers to the percentage of PF-02. The setting range is 0~1000, and the data format is data with one
decimal point.
For example, PF-02 (Driver torque upper limit)=100%, and H1105 is given 500, means that the given torque is
100% * 50.0=50%.

Torque control forward maximum frequency
0.00Hz~max output frequency
It is used to set the maximum forward or reverse operating frequency of the inverter under torque control mode.
The acceleration and deceleration time of the upper frequency limit is set in PC-07 (acceleration) /PC-08
(deceleration).
When the inverter is in torque control, if the load torque is less than the motor output torque, the motor speed
will continue to rise. In order to prevent the mechanical system from speeding and other accidents, it is
necessary to limit the maximum speed of the motor during torque control.
If it is necessary to dynamically and continuously change the maximum frequency of torque control, it can be
achieved by controlling the upper limit frequency.
