p0327[0...n]
Optimum motor load angle / Mot phi_load opt
Access level: 3
Can be changed: C(3), U, T
Units 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.
Caution:
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation 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 (refer to p0300).
p0328[0...n]
Motor reluctance torque constant / Mot kT_reluctance
Access level: 4
Can be changed: C(3), U, T
Units 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.
Caution:
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation 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: 4
Can be changed: C(3), U, T
Units group: -
Min
0.00 [Arms]
Description:
Sets the current for the pole position identification routine.
For a two-stage technique, the current is set for the 2nd phase.
Dependency:
Refer to: p0325, p1980, r1984, r1985, r1987
Caution:
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected. Infor-
mation in p0300 should be carefully observed when removing write protection.
r0330[0...n]
Rated motor slip / Mot slip_rated
Access level: 3
Can be changed: -
Units group: -
Min
- [Hz]
Description:
Displays the rated motor slip.
Dependency:
The rated slip is calculated from the rated frequency, rated speed and number of pole pairs.
Refer to: p0310, p0311, r0313
Note:
The parameter is not used for synchronous motors (p0300 = 2xx).
