Byte 2: Distance To Go; Byte 3: Distance To Go - Siemens SIMATIC S5 Manual

Addressing and Programming
Since exactly the same number of pulses are output in the deceleration phase as
in the acceleration phase, the IP 267 outputs a maximum of 112.5% (3 x 37.5%) of
the specified pulses. The distance to go has a negative sign in this case and the
"DGS" bit is set. You can interrupt your program at this point, if necessary, and
take suitable measures, e.g. start a reference point approach.
