SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009

Description: Sets the cause that should initiate the bypass.

Note: The parameter only has an effect for a non-synchronized bypass.

p1267 bit 0 = 1:

The bypass is initiated by setting a binary signal. When the command is reset, after the debypass delay time

(p1263) has expired, operation at the Motor Module is re-selected.

p1267 bit 1 = 1:

When the speed threshold entered in p1265 is reached, the bypass is switched in. The system only switches back

when the speed setpoint again falls below the threshold value.

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, connect the corresponding control bit as the signal source:

p1269 index 0 = r1261 bit 0

p1269 index 1 = r1261 bit 1

Entering p1269 = 0 sets this parameter assignment automatically for switches without a feedback signal.

Description: Sets the bypass switch monitoring time.

Index: [0] = Switch motor - drive

[1] = Switch motor - line supply

Note: The monitoring is deactivated with p1274 = 0 ms. The changeover time for the bypass (p1262) is extended by the

time set in this parameter.
