[3] = Reserved

Dependency: Refer to: p0205
Description: Sets the drive unit supply voltage (rms value of the phase-to-phase line supply voltage).
Dependency: Set p1254, p1294 (automatic detection of the Vdc switch-on levels) = 0.
The switch-in thresholds of the Vdc_max controller are then directly determined using p0210.
Warning: In the case of regenerative power units (PM250, PM260), the regenerative power limit for U/f control current limita-
tion control is calculated as a proportion of the supply voltage p0210. Therefore, p0210 should not be set to a value
higher than the actual line voltage.
Caution: If the line supply voltage is higher than the entered value, the Vdc controller may be automatically de-activated in
some cases to prevent the motor from accelerating. In this case, an appropriate alarm is output.
Note: Setting ranges for p0210 as a function of the rated power unit voltage:
U_rated = 230 V:
- p0210 = 200 ... 240 V
U_rated = 400 V:
- p0210 = 380 ... 480 V
U_rated = 500 V:
- p0210 = 500 ... 600 V
U_rated = 690 V:
- p0210 = 660 ... 690 V
The pre-charging switch-in threshold for the DC link voltage (Vdc) is calculated from p0210:
Vdc_pre = p0210 * 0.82 * 1.35
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).
