Bypass - Siemens SINAMICS G120 Original Instructions Manual

8.7.15

Bypass

The bypass function switches the motor from inverter operation+ to line system operation.
The following options are possible:
● Bypass function when activating via a control signal (p1267.0 = 1)
● Bypass function depending on the speed (p1267.1 = 1)
The inverter controls two contactors via its digital outputs. The inverter analyses the
feedback signals from the contactors via its digital inputs. If using direct connection logic
(high level = ON), both contactors should be NO contacts.

Flying restart must be activated for the bypass function (p1200 = 1 or 4).
