Continuation takes place dependent on:
– The continuation condition set for the c urrent positioning record,
– The logical status of the digital inputs with the assignment NEXT1 or NEXT2.
Starting the process
The start is made through:
– a rising edge at the digital input “travel to the START position”
Stopping the process
Record continuation is terminated when
– a positioning record is executed with the option END or
– a stop signal is present at the STOP input.
The Stop signal at the STOP input is not executed if the continuation condition “StopIgn”
has been se t for the current positioning record.

Function
START Set positioning records for the Home or S tart position.
When the START signal is set ( 0
}
1), c onfirmation follows via the ACK signal
(1
}
0). The MC signal (Motion Complete) is reset (1
}
0),; the drive carries out the
homing run. When the START signal is reset (1
}
0), c onfirmation follows via the ACK
signal (0
}
1). After completion of the positioning job, the MC signal is set again
(0
}
1).
HOME
NEXT1/2 Subsequent positions of a positioning record for record continuation through
positioning record number and digital inputs.
Execution (travel t o the subsequent position) co rresponds to the logic operation of
the digital inputs NEXT1 and NEXT2 through the step enabling condition of the
positioning record.
The digital inputs N EXT1 and N EXT2 are evaluated only through the step enabling
conditions GoImm, IgnUTP, GoA TP.
STOP Sto p record continuation
0
}
1: Record continuation is stopped. The ongoing positioning is still ended in any
case.
Note: If the positio ning record has the setting “StopIgn”, despite the set STOP input
the positioning record of the subsequent position is started.
The MC signal (Motion Complete) is set (0
}
1), the R EADY signal is reset (1
}
0).
Combined
START/STOP
0
}
1: START position of the record continuation is approached.
1

0: activates Stop function of record continuation
