7.7.2.2 Rotary coding switch
The data of the rotary coding switch (Override) is gray-coded on HT 2. The following table
shows the values in the input data for each switch position:
Switch setting Input data EB m + 5, Bit 5 - Bit 1
E D C B A (gray-coded)
0 0 0 0 0 1
1 0 0 0 1 1
2 0 0 0 1 0
3 0 0 1 1 0
4 0 0 1 1 1
5 0 0 1 0 1

The position of the switch positions on HT 2
Note
The relevant machine data is to be set to the TRUE value on using the rotary coding switch:
• MD12000 $MN_OVR_AX_IS_GRAY_CODE
• MD12020 $MN_OVR_FEED_IS_GRAY_CODE
• MD12040 $MN_OVR_RAPID_IS_GRAY_CODE
• MD12060 $MN_OVR_SPIND_IS_GRAY_CODE
The effective override value comes from the parameterized values in the machine data:
• MD12010 $MN_OVR_FACTOR_AX_SPEED
• MD12030 $MN_OVR_FACTOR_FEEDRATE
• MD12050 $MN_OVR_FACTOR_RAPID_TRA
• MD12070 $MN_OVR_FACTOR_SPIND_SPEED
