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.
4: Pulse pulse (X4)
The target torque is given by terminal X4 high speed pulse.
Given signal specification of pulse: voltage range 9V-30V, frequency range 0kHz-500kHz. Pulse setting can
only be input from the multifunction input terminal X4.
The relationship between input pulse frequency and corresponding setting of terminal X4 is set through
P2-66-P2-69. The corresponding relationship is the linear correspondence of 2 points. The pulse input
corresponds to the percentage of PF-02.
5: Communication given
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.

It is used to set the forward or reverse maximum operating frequency of inverter under torque control mode.
The acceleration and deceleration time of 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 galloping accidents, we must limit the
maximum speed of the motor in torque control.
If the maximum frequency of torque control needs to be dynamically changed continuously, it can be realized
by controlling the upper limit frequency.
Under the torque control mode, the difference between the output torque and the load torque determines the
speed change rate of the motor and the load. The motor speed may change rapidly, causing noise or mechanical
stress too much. By setting the torque control acceleration and deceleration time, the motor speed can change
