p0326[0...n] Motor stall torque correction factor / Mot M_stall_corr
Access level: 4
Can be changed: C(3), U, T
Unit group: -
Min
5 [%]
Description: Sets the correction factor for the stall torque/force at a 600 V DC link voltage.
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
p0327[0...n] Optimum motor load angle / Mot phi_load opt
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
0.0 [°]
Description: Sets the optimum load angle for synchronous motors with reluctance torque.
The load angle is measured at the rated motor current.
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: This parameter has no significance for induction motors.
For synchronous motors without reluctance torque, a angle of 90 degrees must be set.
When quick commissioning is exited with p3900 > 0, then the parameter is reset if a catalog motor has not been
selected (p0300).
p0328[0...n] Motor reluctance torque constant / Mot kT_reluctance
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
-1000.00 [mH]
Description: Sets the reluctance torque constant for synchronous motors with reluctance torque (e.g. 1FE ... motors).
This parameter has no significance for induction motors.
Notice: When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note: For synchronous motors without reluctance torque, the value 0 must be set.
p0329[0...n] Motor pole position identification current / Mot PolID current
Access level: 3
Can be changed: C(3), U, T
Unit group: -
Min
0.0000 [Arms]
Description: Sets the current for the pole position identification routine (p1980 = 1).
For a two-stage technique (p1980 = 4), the current is set for the 2nd phase.
The current for the 1st phase is set in p0325.
Dependency: If a maximum current (p0323) was not parameterized, then p0329 is limited to the rated motor current.
If p0329 is too small in order to determine the pole position (for p1980 = 1), then p0323 must be first parameterized
and significantly greater than p0329.
