646 POSITIVE TORQUE LIMIT 6 (2.6.23.22)
Use this parameter to set the torque limit for positive direction.
649 PMS MOTOR ZERO SHAFT POSITION 6 (2.6.24.4)
Use this parameter to set the zero shaft position.
Updated during encoder identification run with an absolute encoder.
650 MOTOR TYPE 6 (2.6.24.1)
Use this parameter to set the type of motor in your process.

651 FLUX CURRENT KP 6 (P2.6.24.8)
Use this parameter to set the gain for the flux current controller.
Defines the gain for the flux current controller when using a PMS motor. Depending on the
motor construction and the ramp rate that is used to go to the field weakening area, high
gain may be needed so that the output voltage does not reach maximum limit and prevent
proper motor control. Too high gain may lead to unstable control. Integration time is more
significant in this case for control.
652 FLUX CURRENT TIME 6 (P2.6.24.9)
Use this parameter to set the integration time for the flux current controller.
Defines the integration time for the flux current controller when using a PMS motor.
Depending on motor construction and the ramp rate that is used to go to field weakening
area, short integration times may be needed so that the output voltage do not reach
maximum limit and prevent proper motor control. Too fast integration time may also lead to
unstable control.
655 MODULATION LIMIT 6 (2.6.23.34)
Use this parameter to control how the AC drive modulates the output voltage.
Reducing this value limits the maximum output voltage. If a sinusoidal filter is used set this
parameter to 96%.
656 LOAD DROOPING TIME 6 (2.6.18)
Use this parameter to set the drooping time of the motor.
