Xinje VH6 Series - Group PF Torque Control(Firmware Versions below 3720)

155
This group of function codes is the user-defined parameter group (P8-00 is set to 0 and P8-05 is set to 11, used
together).
Users can select the required parameters to be summarized into PE group in all VH6 function codes, which can
be used as user-defined parameters to facilitate the operation of viewing and changing.
PE group provides up to 32 user-defined parameters. When entering user-defined parameter mode, the display
function code is defined by PE-00~PE-31, and the sequence is consistent with PE group function code.
This parameter array can map some discontinuous parameters into PE parameters. When the upper computer
PLC reads the parameters of the converter, it can read all the discontinuous parameters through one instruction,
which can simplify the PLC communication instruction and improve the communication efficiency.

PF-00
Torque control
0: Speed control
1: Torque control
It is used to select the control mode of frequency converter: speed control or torque control, which cannot be
switched during the operation of inverter.
The X terminal of VH6 has a function related to torque control: torque control inhibition (function 29).
When the speed control / torque control switching terminal is invalid, the control mode is determined by PF-00.
If the speed control / torque control switching is effective, the control mode is equivalent to the reverse value of
PF-00.
Note: Torque mode is only valid in vector control mode.

-200.0%~200.0%
PF-01 is used to select the torque setting source. There are eight torque setting modes.
The torque setting adopts relative value, and 100.0% corresponds to the rated torque of the motor. The setting
range is - 200.0% ~ 200.0%, indicating that the maximum torque of the inverter is twice the rated torque of the
inverter.
When the torque is set to be positive, the inverter runs forward;
When the torque is set to be negative, the inverter runs reverse.
The torque setting sources are described as follows:
0: Digital setting (PF-02)
The target torque directly uses the PF-02 setting value.
