Figure 6-64 Changeover depending on the speed (p1267.1 = 1)
If the speed setpoint r1119 lies above the bypass speed threshold p1265, the inverter switches
the motor to line operation.
If the speed setpoint falls below the bypass speed threshold, the inverter switches the motor
to inverter operation.
Interaction with other functions
● Flying restart
The "Flying restart" function must be activated for the "Bypass" function (p1200 = 1 or 4).
Flying restart – switching on while the motor is running (Page 340)
● Emergency operation
The activated "Essential service mode" function influences the "Bypass" function.
Essential service mode (Page 245)
● Inverter control
For operation of the motor on the line supply, the inverter no longer responds to the OFF1
command, but rather only to OFF2 and OFF3.
