Target recognition (Motion complete/MC)
A force record is considered complete when the following two conditions are fulfilled:
– The sum of the difference between the target force and the actual force calculated from the current
is less than or equal to the specified maximum value (identical for all records, FCT, “Messages”
page).
– The first condition has at least been fulfilled over the specified time period (“MC damping time”,
identical for all records, FCT, “Messages” page).
Behaviour after target recognition:
As long as no other drive function is executed, the drive will continue to run or press in a controlled
manner with the setpoint force. The speed is limited to the maximum value specified in the force
record. Stroke limitation remains active.
Digital output no. 15 MOV as well as the force and position comparators are of particular interest in this
regard (see section 5.9).
Stroke limitation (type “FSL”)
Upon reaching the stroke limit the drive is braked via the quick stop ramp ( FCT, “Axis”: “Quick Stop”
panel). As long as no other drive function is executed, the drive will stop at the limit stroke in a position-
controlled manner. Standstill monitoring is activated.
Stroke = sum of the difference between the actual position and the position at the start of the record.
5.7 Record switching by PLC (binary profile)
This section explains how the record switching function operates in the binary profile.
Another record can be switched to at any time in the valve profile by setting a different
input.
Record switching in the binary profile enables a PLC to switch flexibly between records. A specification
can be made here for each record regarding how the drive should behave when this record is to be
started while another record is being executed at the same time.
The following behaviour (start conditions) can be parameterised:
– Ignore: The START command is ignored. The current record is completed. A new record can only be
started if the MC is active (new START signal required). This is the default setting.
– Delay: The current record is completed. The subsequent record addressed by the START signal is
started after the current record has ended (immediately after the MC signal).
– Interrupt: The current record is interrupted immediately and the newly addressed record is
executed directly.
