P4-09 Max. regenerative torque limit

Setting range: P4-08 – 200 – 500%

Defines the current limit in regenerative mode. The value of this parameter represents the percentage value of the rated motor current defined in P1-08. The current limit specified in this parameter overrides the normal torque-generating current limit when the motor operates in regenerative mode. If the value is too high, the result is an excessive motor current distortion causing the motor to behave unstable in regenerative mode. If the value is too small, the output torque of the motor might drop in regenerative mode.
