IP 240 Positioning
If the channel was structured for backlash compensation and the actual position is above the
target position (RICH=1), output D2 is automatically set if the IP outputs have been enabled.
When the BEE2 range is exited, the IP output must be reset via the S5 CPU by transferring control
bit FREI=0 to the IP 240.
The following table shows you how the IP 240 uses the various combinations of status bits BEE1 to
BEE3 to set the IP outputs and generate interrupts. Note the differences produced by backlash
compensation/no backlash compensation.

With backlash compensation
E.g.: Start in zone BEE2=0/BEE3=1 The drive is between cut-off point and target range.
RICH=1 The drive is above the target position.
Interrupt BE1 The drive must traverse at creep speed .
DA2=1 The drive switched on to ”overrun the position” via D2.
