SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the current for the 1st phase of the two-stage technique for pole position identification routine.
The current of the 2nd phase is set in p0329.
The two-stage technique is selected with p1980 = 4.
Dependency: Refer to: p0329, p1980, r1984, r1985, r1987
Notice: When the motor code (p0301) is changed, it is possible that p0325 is not pre-assigned.
p0325 can be pre-assigned using p0340 = 3.
Note: The value is automatically pre-assigned for the following events:
- For p0325 = 0 and automatic calculation of the closed-loop control parameters (p0340 = 1, 2, 3).
- for quick commissioning (p3900 = 1, 2, 3).
Description: Sets the correction factor for the stall torque/force at a 600 V DC link voltage.
Caution: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). 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 (refer to p0300).
Description: Sets the optimum load angle for synchronous motors with reluctance torque.
This parameter has no significance for induction motors.
The load angle is measured at the rated motor current.
Caution: This parameter is automatically preset for motors from the motor list (p0301).
When selecting a catalog motor, this parameter cannot be changed (write protection). Information in p0300 should
be carefully observed when removing write protection.
Note: 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).
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: This parameter is automatically preset for motors from the motor list (p0301). When selecting a catalog motor, this
parameter cannot be changed (write protection). Information in p0300 should be carefully observed when removing
write protection.
Note: For synchronous motors without reluctance torque, the value 0 must be set.
