Absolute offsetlimits via ADS

Absolute offsetlimits

Additional to the relative offset limits of teh axis parameter list or by CNC-program, the offset limits also can be specified in absolute manner.

The absolute offset limits are given in [0.1 um] after activation of manual mode and can be modified by ADS-writeacces. The offset limits are valid for the operation modes:

handwheel
incremetal jog (JOG)
continuous jog (TIPP)

If during setting of new limits the axis are outside of the limit range, they just can be moved in direction of valid range.

Notice
Additionally for writing new limits via ADS, there exists an ADS-interface for reading the active limits. After each command of new offset limits via ADS, the correct activation of the new offsets shall be verified be reading the active limits.

Reading by PLC, active limits

fbRead : ADSREAD;
fbRead( NetID := '',
        Port := 551,
        IdxGrp := 16#00021301 +ChannelIdx,
        IdxOffs := 16#0001001E +  16#00010000*AxisIdx,
        LEN := 4,
        DestAddr := pDest,
        READ := fStarted, TMOUT := T#1s);

Writing by PLC, command limits

writeOffsetMin1 : ADSWRITE;
writeOffsetMax1 : ADSWRITE;
writeOffsetMin1( NetID := '',
                 Port := 551,
                 IdxGrp := 16#00021301,
                 IdxOffs := 16#00010019,
                 LEN := 4,
                 SrcAddr := ADR(NewOffsetMin1),
                 WRITE := fWrite1, TMOUT := T#1s);
writeOffsetMax1( NetID := '',
                 Port :=551,
                 IdxGrp := 16#00021301,
                 IdxOffs := 16#0001001A,
                 LEN := 4,
                 SrcAddr := ADR(NewOffsetMax1),
                 WRITE := fWrite1, TMOUT := T#1s);
