Description:
Displays the maximum output current of the power unit.
Index:
[0] = Catalog
[1] = Load duty cycle with high overload
[2] = Load duty cycle with low overload
[3] = Reserved
[4] = 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 V/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 deactivated 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:
V_rated = 230 V:
- p0210 = 200 ... 240 V
V_rated = 400 V:
- p0210 = 380 ... 480 V
V_rated = 500 V:
- p0210 = 500 ... 600 V
V_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:
V_rated = 400 V:
- U_min = p0210 * 0.78 > 360 V
V_rated = 500 V:
- V_min = p0210 * 0.76
V_rated = 690 V:
- U_min = p0210 * 0.74 > 450 V
