Buffer for faults and alarms
Note
A fault buffer and alarm buffer are provided for each drive.
The drive and device-specific
messages are entered in these buffers.
The contents of the fault buffer are saved to the non
-volatile memory when the Control Unit
is powered down, i.e.
the fault buffer history is still available when the unit is powered up
a
gain.
Note
The entry in the fault/alarm buffer is made after a delay. For this reason, the fault/alarm
buffer should not be read until a change in the buffer is also recognized (r0944, r2121) after
"
Fault active"/"Alarm active" is output.
