Note:
When setting a value for the braking power, the following calculations are made:
- p1240, p1280: Vdc_max control is deactivated.
- p1531 = - p0219: the power limit when generating is set (limited to - p1530).
- the minimum ramp-down time is calculated (p1127) as a function of p0341, p0342 and p1082 (not for vector control
with speed encoder).
If the parameter is reset again to zero, then the Vdc_max controller is reactivated and the power limit as well as the
ramp-down time are recalculated.
Description:
Sets the type of the filter at the motor side.
Value:
0:
No filter
1:
Motor reactor
2:
dv/dt filter
3:
Sine-wave filter Siemens
4:
Sine-wave filter third-party
Dependency:
The following parameters are influenced using p0230:
p0230 = 1:
--> p0233 (power unit, motor reactor) = filter inductance
p0230 = 3:
--> p0233 (power unit, motor reactor) = filter inductance
--> p0234 (power unit sine-wave filter capacitance) = filter capacitance
--> p0290 (power unit overload response) = inhibit pulse frequency reduction
--> p1082 (maximum speed) = Fmax filter / pole pair number
--> p1800 (pulse frequency) >= nominal pulse frequency of the filter
--> p1802 (modulator modes) = space vector modulation without overcontrol
p0230 = 4:
--> p0290 (power unit overload response) = inhibit pulse frequency reduction
--> p1802 (modulator modes) = space vector modulation without overcontrol
The user must set the following parameters according to the data sheet of the sine-wave filter and also the user must
check whether they are permitted.
--> p0233 (power unit, motor reactor) = filter inductance
--> p0234 (power unit sine-wave filter capacitance) = filter capacitance
--> p1082 (maximum speed) = Fmax filter / pole pair number
--> p1800 (pulse frequency) >= nominal pulse frequency of the filter
Refer to: p0233, p0234, p0290, p1082, p1800, p1802
Note:
The parameter cannot be changed if the power unit (e.g. PM260) is equipped with an internal sine-wave filter.
For sine-wave filters, the test pulse evaluation to detect short-circuits is always deactivated.
If a filter type cannot be selected, then this filter type is not permitted for the power unit.
p0230 = 1:
Power units with output reactor are limited to output frequencies of 150 Hz.
p0230 = 3:
Power units with sine-wave filter are limited to output frequencies of 200 Hz.
