Fig. 13−32 Signal flow: motor control ˘ PLC
The motor control is provided with different monitoring functions, protecting the drive
against impermissible operating conditions.
If a monitoring function is activated,
ƒ the corresponding response for device protection is initiated.
ƒ the fault indication is entered on the first position in the history buffer ( 237).
ƒ a corresponding variable is set to TRUE as long as the trigger condition is fulfilled.
The variables of the monitoring function can be processed in the application program
of the PLC.
The current error number is also displayed in the variable DCTRL_wFaultNumber after the
PLC has been started.
In the fault history buffer (C0168/x), fault messages are saved in codes as 4−digit numbers.
The first digit describes the type of fault response. The last three digits correspond to the
fault number.
