Bit 12
All conditions are fulfilled. The release of the drive can be given via the
Enable input.
Enable active Bit 0 Displays that the drive is in the state Enable.
Ready to start Bit 1
This output signal indicates that the controller can accept a "Start" com-
mand or that the old command has been processed.
In operation Bit 13 The rotary indexing table carries out a rotating movement.
Indexer in
position
Bit 2
This output signal indicates that the rotary indexing table is in a locked
position. A position cam is mounted on the rotary indexing table for this
purpose. The signal from the position cam is sent to this output without
being changed (1:1).
If this output signal is HIGH again after the end of the cycle, then proces-
sing can be started because the rotary indexing table is no longer
moving. The motor of the rotary indexing table will however continue to
move as long as specified by the stop delay or stop ramp that was set, in
order to reach an optimal starting position for the next cycle.
If, however, this output signal is LOW, then processing
must be stopped immediately because the rotary indexing table has left
its position.
Stop selected Bit 3 Direct feedback from the Stop input.
Alarm timeout Bit 4
The rotary indexing table did not reach the next locking position within the
specified time.
Alarm position
run over
Bit 5
This output signal indicates that the position cam of the rotary indexing
table was overrun.
If this error message is received, then processing must
be stopped immediately because the rotary indexing table has left its
position.
Alarm safety Bit 6 Internal safety function has detected a fault.
Sum error Bit 7 This output indicates the presence of a warning.
Sum warning Bit 8 This output indicates the presence of an error.
