Reference movement, variant 1
1. Travel with preset speed and direction (speed and direction for reference
movement) until the corresponding limit switch is active. If counting upwards
during the reference movement, END+ must be reached. Otherwise END-.
2. Inversion of the direction of movement. Leave the limit switch slowly. Continue
until zero impulse (TRACK N).
3. Deletion of the counter and switch off outputs DIR+ and DIR- or TRAVERSE.
Conclusion of a successful reference movement is reported to the PLC.
The signal is deleted when the operating mode changes.
If the “other” limit switch is active during the reference movement, the outputs
DIR+ and DIR- or TRAVERSE are switched off. The outputs can only be reactivated
when the operating mode OFF has been set.
Reference movement, variant 2
1. Travel with preset speed and direction (speed and direction for reference
movement) until the corresponding limit switch is active. If counting upwards
during the reference movement, END+ must be reached. Otherwise END-.
2. Inversion of the direction of movement. Leave the limit switch slowly.
3. Deletion of the counter and switch off outputs DIR+ and DIR- or TRAVERSE.
Conclusion of a successful reference movement is reported to the PLC.
The signal is deleted when the operating mode changes.
If the “other” limit switch becomes active during the reference movement, the
outputs DIR+ and DIR- or TRAVERSE are switched off. The outputs can only be
reactivated when the operating mode OFF has been set.
Reference movement, variant 3
1. Travel with preset speed and direction (speed and direction for reference
movement) until END+ = 1 (24 V) (alternative use of this limit switch).
2. Proceed in the same direction slowly until zero impulse (TRACK N).
3. Deletion of the counter and switch off outputs DIR+ and DIR- or TRAVERSE.
Conclusion of a successful reference movement is reported to the PLC.
The signal is deleted when the operating mode changes.
END- is not evaluated during the reference movement.
