Megmeet MV300 Series - Torque Control Parameters (Group P06)

140
When P05.13 or P05.14 is selected to be 0, P05.15 and P05.16 are used to limit the maximum output
torque of the drive. The limit value is the percentage of the rated output torque of the motor. When large
negative torque is required, please adopt additionally the dynamic braking method.
Leave-factory values: 180.0% for P-type, 150.0% for G-type.
0: Decelerate to stop
1: Coast to stop, display Er.dEv
2: Continue to run
Detection method for large set speed deviation (DEV)
When the speed deviation (difference between the command speed and real speed of the motor)
exceeds the setting value of P05.21 and the lasting time of such status exceeds that set by P05.22, large
speed deviation will be detected. Set P05.21 with the maximum output frequency as 100%.
 Note
The detection of large speed deviation (DEV) is enabled only under the speed control mode (P06.00=0).
6.6 Torque control parameters (Group P06)
The switching between speed control and torque control can be realized through this function code.
0: Speed control mode
The motor action is controlled by the speed command, and the internal ASR is enabled. The speed
control mode shall be used together with the electric torque limit value and the braking torque limit value.
1: Torque control mode
The internal ASR is disabled and the torque command reference be selected according to function code
P06.02. When the torque control mode is used, the motor speed may increase because the torque
command does not match the load torque. Please remember to set the speed limit value.
 Note
Under vector control mode, it can be switched between speed control mode and torque control mode through
terminal. If P06.00 is set as 0 and the terminal function (47) is disabled, it is under speed control. If the
terminal function is enabled, it switches to the torque control. If P06.00 is set as 1 and the terminal function
(47) is disabled, it is under the torque control. If the terminal function is enabled, it switches to the speed
control. Please refer to the description of the terminal function of Multi-functional terminals P09.00~ P09.05:
“47: speed control/torque control switching terminal”.
