10.314 (ID 645) Negative Torque Limit
Location in the menu:
P2.6.15.21
(Multi-Pump Control Application)
Use this parameter to set the torque limit for negative direction.
10.315 (ID 646) Positive Torque Limit
Location in the menu:
P2.6.15.22
(Multi-Pump Control Application)
Use this parameter to set the torque limit for positive direction.
10.316 (ID 649) PMS Motor Zero Shaft Position
Location in the menu:
P2.6.16.2
(Multi-Pump Control Application)
Use this parameter to set the zero shaft position.
Updated during encoder identification run with an absolute encoder.
10.317 (ID 650) Motor Type
Location in the menu:
P2.6.16.1
(Multi-Pump Control Application)
Use this parameter to set the type of motor in your process.
10.318 (ID 651) Flux Current KP
Location in the menu:
P2.6.16.8
(Multi-Pump Control Application)
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 can be needed so that the output voltage does not reach maximum limit
and prevent proper motor control. Too high gain can lead to unstable control. Integration time is more significant in this case for
control.
10.319 (ID 652) Flux Current Time
Location in the menu:
P2.6.16.9
(Multi-Pump Control Application)
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 can be needed so that the output voltage does not
reach maximum limit and prevent proper motor control. Too fast integration time can also lead to unstable control.
10.320 (ID 655) Modulation Limit
Location in the menu:
P2.6.15.34
(Multi-Pump Control Application)
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%.
