The two reference markers belong to the block (index) that defines a positioning step. (For the description of
the positioning indexes see chapter 7.12.4.8 "Sequential positioning"). In connection with the reference marker,
it is useful to define index blocks even for single positionings.
Example:
Start
PS.47 = 1000
1000
Reference marker 1
From a starting position, an undercarriage shall drive to 4 different positions . The positions of target 1...4 are
always approached from the left, the start always from the right. For the targets, therefore, reference markers

PS.46 = 3500
PS.46 = 2500
PS.46 = 1750
PS.46 = 1000
2000 3000 4000
Reference marker 2
PS.00 / bit 6...7 = 0: Stop
Reference marker recognised during the decele-
ration phase of the target approach.
Adjustment of the position is executed, but po-
sitioning to the target position is not possible
anymore.
(S-curve time too small or adjustment factor for
ramps in PS.44 set too small).
With the beginning of the lower S-curve, the
drive signals "position inaccessible"via a digital
output.
Only with deactivation of the positioning module,
the output "target inaccessible" is reset.
PS.00 / bit 6...7 = 64: Stop + new attempt
Reference marker recognised during the decele-
ration phase of the target approach.
Adjustment of the position is executed, but po-
sitioning to the target position is not possible
anymore.
With the beginning of the lower S-curve, the
drive signals "position inaccessible"via a digital
output
After reaching standstill, the drive automatically
starts a new positioning to the target position.
The output "target inaccessible" is reset automa-
tically
