The undervoltage thresholds for the DC link voltage (Vdc) are calculated from p0210 as a function of the rated
power unit voltage:
U_rated = 400 V:
- U_min = p0210 * 0.78 > 360 V
U_rated = 500 V:
- U_min = p0210 * 0.76
U_rated = 690 V:
- U_min = p0210 * 0.74 > 450 V
Description: Sets the braking power of the connected braking resistor.
Dependency: Refer to: p1127, p1240, p1280, p1531
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 con-
trol 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
