High-end and Low-end limits
This function releases an Emergency command to the drive if any of the end limits
are active. Two separate end limits,
LOWEND PTR
can be configured to be used in the forward (up) and reverse (down) direction,
respectively. The two limits are independent of each other, and thus, they get
activated only if configured properly. The HIGHEND input (active when DI = 0 if the
pointer value is used after inverting the bit value) should be wired to the forward (up)
limit switch, while the LOWEND input (active when DI = 0 if the pointer value is used
after inverting the bit value) should be used for the reverse (down) limit switches.
The function releases an Emergency command (OFF3) if the HIGHEND input gets
activated while the drive is running in the forward (up) direction. The drive then
decelerates according to the EM STOP RAMP TIME
. The HIGHEND input
should be inactive for the drive to release a new start sequence in the forward
direction. However, the drive can be run in the reverse (down) direction when the
HIGHEND input is active. The drive generates a HIGHEND LIMIT warning on the
activation of the HIGHEND command.
Similarly, an Emergency command (OFF3) is released if the LOWEND input gets
activated while the drive is running in the reverse (down) direction. The drive then
decelerates according to the EM STOP RAMP TIME
. The LOWEND input
should be inactive for the drive to release a new start sequence in the reverse
direction. However, the drive can be run in the forward (up) direction when the
LOWEND input is active. The drive generates a LOWEND LIMIT warning on the
activation of the LOWEND command. If the warnings do not need to be shown in the
control panel or fault logger, they can be blocked. See
on page
If the drives are in a Master/Follower configuration and in EXT2 control, all the drives
will stop when a HIGHEND or LOWEND command comes from any of the drives.
