10.1.2 Dimension reference system:
–
Linear drive system: end position facing the motor, retracted
–
Rotary drive system: left
–
Parameter "End Position Out": maximum possible value of the relevant mechanics
10.2.5 Switch-on behaviour
The switch-on behaviour of the EMCS-ST depends on the following conditions:
– Commissioning
– Restart (error acknowledgement)
– Logic voltage failure [Logic]
–
Load voltage failure [Power]
–
Power failure [Logic], [Power]
The logic voltage [Logic] L must be switched on 50 ms after the load voltage [Power] when switching
on the power supplies.
If the logic voltage is switched on before the load voltage, the EMCS-ST starts with an error that must
be acknowledged.
Timing: switch-on behaviour
The diagram shows the switch-on behaviour of the EMCS-ST from switching on the power supplies to
reaching the "Ready for operation (system not referenced)" status.
