Positioning type = ABSOLUTE
Example 1 (PSW.12 = "0"):
P81:4 = 315
P82:4 = –100
––> Traverse with 100 % to 315° negative
Example 2 (PSW.12 = "0"):
P81:4 = 315
P82:4 = 100
––> Traverse with 100 % to 315° positive

The following should be observed for the signaling position:
S
Before SW 1.3 the following applies:
– The drive has precisely one zero position (refer to Chapter
5.5.1). The signal position is viewed, referred to this position.
– A modulo evaluation is not made.
S
From SW 1.3, the following applies:
– The signal position is saved, evaluated as modulo value
The software limit switches act the same as for a linear axis.
S
P6 Software limit switch, start (refer to Chapter 5.6.2)
S
P7 Software limit switch, end
The software limit switches are de–activated with P6 = P7.
