Description of Parameters
636 Minimum frequency for Open
Loop torque control
6 (P1.10.8)
Defines the frequency limit below which the frequency converter operates in the
frequency control mode.
Because of the nominal slip of the motor, the internal torque calculation is inaccurate
at low speeds where it is recommended to use the frequency control mode.
637 Speed controller P gain, Open
Loop
6 (P1.6.13)
Defines the P gain for the speed controlled in Open Loop control mode.
638 Speed controller I gain, Open
Loop
6 (P1.6.14)
Defines the I gain for the speed controlled in Open Loop control mode.
639 Torque controller P gain 6 (P1.10.9)
Defines the P gain of the torque controller.
640 Torque controller I gain 6 (P1.10.10)
Defines the I gain of the torque controller.
641 Torque reference selection 6 (P1.10.4)
Defines the source for torque reference.
