Automatic control function programming manual ladder language

- Select spindle b control: COMBRb = 1
- Read the miscellaneous function for the
group (M3 or M4) defining spindle
rotation direction:
. M04_g = 1: counterclockwise
. M03_g = 1: clockwise
- Add the sign bit depending on the
spindle rotation direction to the spindle
speed:
Sign
In the programme
VITBRb
- Load the value obtained in the spindle
speed setting: C_VITBRb
Programming of
a spindle assigned to
axis group g
In the programme
- read the spindle number (b) assigned
to group g:
. M61_g = 1: no spindle assigned
. M64_g = 1: spindle 1
. M65_g = 1: spindle 2
. M62_g = 1: spindle 3
. M63_g = 1: spindle 4
Requirements:
- Spindle parameterised (see
Parameter Manual)
- Spindle address wired (see
Installation Manual)
. @24: spindle 1 @25: spindle 2
. @26: spindle 3 @27: spindle 4

Variables
Unmeasured spindle controlled
by DAC of the machine processor, of
an 8I/8O analogue card or of the UCSII
- Read the group miscellaneous function
(M3 or M4) defining the spindle rotation
direction:
. M04_g = 1: counterclockwise
. M03_g = 1: clockwise
- Read VITBRb and encode the speed
according to the DAC
- Send the DAC the sign corresponding
to the rotation direction and the
encoded speed
