7.4.2.4 Check-back (4.3.4)
When the motor is started the Check-back status is expected within 300 ms, otherwise a fault is
detected.
Selectable by parameter Check-back: Motor current or Auxiliary contact signal can serve as check-
back status.
Remark:
Check-back = Simulation is recommended only to be set via Control Panel during commissioning.
The control system is only allowed to set Auxiliary contacts or Motor current to guarantee that the
check-back operates correctly after next power up.
7.4.2.5 Fault behaviour
All kinds of detected external and internal faults set the internal fault bit. Result:
 Contact DO0 or DO1 for the contactor coil opens,
 the monitoring signal FAULT is sent to the fi eldbus,
 the red LED lights on and
 the FAULT signal on the Control Panel display fl ashes.
 If parameterized the output DO2 switches on.
If a motor overload is the cause of the fault signal, the cooling time is started additionally .
The Cooling time is a parameter and can be adjusted. The running cooling time is shown on the Cont-
rol Panel with „°C“.
All faults (except communication fault) must be acknowledged via fi eldbus (4.2.1), via Control Panel (8.1.3)
or if parameterized via multi-function inputs (4.3.4) to allow to start the motor.
Additional the cooling time (4.3.4) must have elapsed to allow to restart the motor with a 01 transition
of the RUN command (4.2.1).
More detailed information are monitored in the diagnosis telegram (4.2.1) and on the Control Panel (8.2.1).
7.4.2.5 Addressing (3.3.1)
The slave address of the UMC22-FieldBusPlug combination is not a parameter but can be set with
Control Panel (8.2.2) or with separate Addressing Set.
