22 Control and controller functions
3.2.11 Troubles
The control device controls
- the mains voltage (phase sequence, - outage)
- the speed
- the heat sink temperature
- the encoder signals
- the motor start-up
- the motor direction
- the motor temperature.
The run program will be stopped if the controller
identifies troubles. The controller blocks the
power semi-conductors. The output relay
"mechanical brake - MB" and "Fault - ST" are
switching off immediately.
The main control system must close the spring-
loaded safety brake and open the main
contactor "K0".
If an error occurs during running, the drive is
delayed because of the braking torque of the
spring-loaded safety brake.
In order to acknowledge the error, the triggering
of the controller release "RF" has to be stopped.
After switching the controller release "RF" on
again, the fault relay "ST" picks up again.

Figure 3.12 Consequence of the trouble and acknowledgement
Exception:
After mains phase outage, excess temperature of the heat sink or of the motor the output relay
automatically picks up after the trouble has been eliminated when parameter /INTERFACES/QUIT is
switched on (factory setting is OFF).
Specific control device monitorings can be switched off in /ZA_INTERN/MASK1 to MASK3
(described in 4.3.11).
