Parameters
List of Parameters
r1969
Speed_ctrl_opt moment of inertia determined / n_opt M_inert det
Access level: 4
Can be changed: -
Units group: 25_1
Min
- [kgm²]
Description:
Displays the determined moment of inertia of the drive.
After it has been determined, the value is transferred to p0341, p0342.
Dependency:
IEC drives (p0100 = 0): unit kg m^2
NEMA drives (p0100 = 1): unit lb ft^2
Refer to: p0341, p0342, p1959
Refer to: F07984
r1970[0...1]
Speed_ctrl_opt vibration test vibration frequency determined / n_opt f_vibration
Access level: 4
Can be changed: -
Units group: -
Min
- [Hz]
Description:
Displays the vibration frequencies determined by the vibration test.
Index:
[0] = Frequency low
[1] = Frequency high
Dependency:
Refer to: p1959
Refer to: F07985
p1980[0...n]
PolID technique / PolID technique
Access level: 4
Can be changed: U, T
Units group: -
Min
1
Description:
Sets the pole position identification technique.
Value:
1:
4:
6:
10:
Dependency:
Refer to: p1780
Note:
Voltage pulse technique (p1980 = 1, 4) cannot be applied to operation with sine-wave output filters (p0230).
r1984
PolID angular difference / PolID ang diff
Access level: 4
Can be changed: -
Units group: -
Min
- [°]
Description:
Displays the angular difference between the actual electrical commutation angle and the angle determined by the
pole position identification.
Dependency:
Refer to: p0325, p0329, p1980, r1985, r1987
Note:
When the pole position identification routine is executed several times, the spread of the measured values can be
determined using this value. At the same position, the spread should be less than 2 degrees electrical.
