If reference travel is started with the IPOS

to the falling edge of the reference cam or to the zero pulse after the falling edge of the
reference cam, depending on whether the argument "ZP" or "CAM" is set.
6.6.3 Type 2: CW end of the reference cam
The reference position is the right end of the reference cam or the first zero pulse to the
right after the end of the reference cam.
One of the binary inputs P600 ... 606 must be set to "REFERENCE CAM".
The reference travel starts in a CW direction; P901 Reference speed 1 is used up to the
first positive edge of the reference cam, then P902 Reference speed 2 is used.
If reference travel is started via the positive edge on the "REF.TRAVEL START" input,
the drive is either referenced to the falling edge of the reference cam or to the zero pulse
after the falling edge of the reference cam, depending on the setting in P904 Referenc-
ing to zero pulse.
If reference travel is started with the IPOS
plus®
command Go0, the drive is referenced
to the falling edge of the reference cam or to the zero pulse after the falling edge of the
reference cam, depending on whether the argument "ZP" or "CAM" is set.
