Temperature monitoring and overload protection in bypass mode
● If the motor is running in bypass mode, while the inverter is in the "ready and bypass"
state (r899.0 = 1 and r0046.25 = 1), then the motor temperature monitoring via the
temperature sensor is active.
● Install the overload protection for the motor bypass mode.

Description
Bypass configuration
Activating the bypass function
Bypass control/status word
Control and feedback signals for the bypass function.
Bypass dead time
Changeover time for contactors. This should be longer than the motor's de-
magnetizing time!
Debypass delay time
Delay time for switching back to inverter operation.
Bypass delay time
Delay time for switching to bypass mode.
Bypass speed threshold
Speed threshold for switching to bypass mode.
Bypass control command
Signal source for switching to bypass mode.
Bypass changeover source configuration
Switch to bypass mode using speed threshold or control signal.
Bypass switch feedback
Signal source for contactor feedback for bypass mode.
Bypass switch monitoring time
Monitoring time setting for bypass contactors.
