SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 06/2011
Description: Sets the signal source for the feedback signal of the bypass switch.
Index: [0] = Switch motor/drive
[1] = Switch motor/line supply
Note: In the case of switches without a feedback signal, interconnect the corresponding control bit as the signal source:
BI: p1269[0] = r1261.0
BI: p1269[1] = r1261.1
Entering p1269 = 0 sets this interconnection automatically for switches without a feedback signal.
Description: Sets the monitoring time for the bypass switch.
Index: [0] = Switch motor/drive
[1] = Switch motor/line supply
Note: The monitoring is de-activated with p1274 = 0 ms.
The changeover time for the bypass (p1262) is extended by the value in this parameter.
Description: Sets the configuration of the controller for the DC link voltage (Vdc controller) in the U/f operating mode.
Value: 0: Inhib Vdc ctrl
1: Vdc_max controller enable
Note: For high input voltages (see p0210), the following settings can improve the degree of ruggedness of the Vdc_max
controller:
- Set the input voltage p0210 as low as possible (in so doing avoid A07401).
- Set the rounding times (p1130, p1136).
- Increase the ramp-down times (p1121).
- Reduce the integral time of the controller (p1291) (factor 0.5).
- Activate the Vdc correction in the current controller (p1810 bit 1 = 1) or reduce the derivative action time of the
controller (p1292) (factor 0.5).
In this case, we always recommend using vector control (p1300 = 20) (Vdc controller, see p1240).
