When using this function, the user needs to define the function of the AI terminal as the torque command
reference. Taking AI1 as an example, set the unit place of the function code P10.01 as 8. Please refer to
the descriptions in Group P10 for the detailed settings.
2: The torque command is set by the terminal PULSE
The maximum value of the terminal PULSE input frequency corresponds with 300
％ of the rated torque.
Please refer to the description in Group P10 for the correspondence between the PULSE input and the
torque. The terminal PULSE selects the positive and negative value of the torque command based on the
pulse reference central point.
The torque reference pulse is only valid for X6. The user needs to set the function of X6 as the torque
reference pulse terminals and set the function code P09.06 (or P09.07) = 53.
3: The torque command is set by communication
The current torque command of the drive is set by the host device with the standard RS485
communication port built in the drive.
For the detailed programming methods, operation methods and communication protocols, please refer to
the MODBUS communication protocol.
4: The torque command is set by the process closed loop output
The process closed loop output is used as the torque command reference. Please refer to the
descriptions in Group P14 for the detailed setting methods of the process closed loop.
5: Reserved
The digital setting range of the torque command is -300.0％~+300.0％.
It sets the torque acceleration/deceleration time upon torque control. This function code is disabled under
the speed control mode.
The time the system takes to reach the reference torque from the current torque.
Start the drive under the torque control mode and run with a speed. When the output torque reaches the
torque switching point P06.05, after the speed/torque switching delay time P06.06 is reached, switches
the drive back to the torque control mode to run.
If the terminals X1~X6 are used to switch the torque and speed control modes, P06.05 is disabled.
P06.06 is the delay time for the switching between the torque and speed control modes.
 Note
1. If you need to switch the torque and speed control modes with the terminals X1~X6, please set one of the
function codes among P09.00~P09.05 to be 47 and set the current control mode as the vector control mode.
2. It can not switch to the torque control mode in the special speed control running modes like the PLC,
process closed loop and multi-speed running.
