Power Unit Configuration / Pu Config - Siemens SINAMICS G150 Manual

2 Parameters
2.2 List of parameters
The pre-charging switch-in threshold for the DC link voltage (Vdc) is calculated from p0210:
Vdc_pre = p0210 * 0.82 * 1.35 (AC/AC)
Vdc_pre = p0210 * 0.82 (DC/AC)
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 (AC/AC) > 330 V, p0210 * 0.60 (DC/AC) > 380 V
U_rated = 500 V:
- U_min = p0210 * 0.76 (AC/AC) > 410 V
U_rated = 660 ... 690 V:
- U_min = p0210 * 0.82 (AC/AC) > 565 V, p0210 * 0.63 (DC/AC) > 650 V
U_rated = 500 ... 690 V:
- U_min = p0210 * 0.82 (AC/AC) > 420 V, p0210 * 0.63 (DC/AC) > 480 V

Description: Sets the power unit configuration.

Dependency: Re bit 00:
Reduced supply voltages are only possible on booksize power units.
Bit 0 = 1 can only be set if r0192.22 = 1.
Refer to: r0192, p0210
Caution: Re bit 00:
Working with reduced input voltages de-activates undervoltage detection.
This function may only be used by personnel with expert knowledge!
Re bit 03:
If the automatic setting of the Vdc max limit is deactivated, then all of the components connected to the DC link must
be suitable for the maximum DC link voltage of the power unit (e.g. 820 V for 400 V units).
Note: Re bit 00 = 0:
It is not possible to reduce the supply voltage in p0210 to below 180 V.
Re bit 00 = 1:
With this setting the supply voltage in p0210 can be reduced to 70 V. Bit 0 = 1 can only be set for booksize power
units with a rated power of up to 40 kW.
The activation of this function is retentively saved in the unit and for incorrect design of the application can result in
loss of warranty!
Re bit 05 = 1:
The status of the inputs/outputs for the power unit contactors is displayed in r0256.
This only applies to chassis power units with 3 AC line connection and line contactors.
The status display is only effective after parameter save and POWER ON.
