2. If the home switch signal is equal to 1 and on the right hand side of the reference mark (due to the
gap: refer to §12.9
for more information), the motor moves in the negative direction until the
reference mark is found.
3. If the home switch signal is equal to 0, the motor moves in the negative direction until the
reference mark is found.
Remark: If K58≠2 when K40=35, the HOME NOT POSSIBLE error (M64=69) will appear instead of the
SING IDX SEARCH error (M64=62).
K40 = 36:
Same as K40 = 2 except for case 3 which is different.
The motor is on the right of the home switch at the beginning of the homing. It moves up to the mechanical end
stop and then comes back the distance given by parameter K46. If the index is not found during the return, the
SING IDX SEARCH error (M64=62) appears. If the home switch is found (in the wrong direction), the motor
moves the distance given by parameter K48 in the opposite direction of the homing to leave the home switch
(parameter K48 must be bigger than the home switch length). Then, it comes back towards the home switch
in the right direction.
Remark: When a DSCDM is used with K40 = 36 and 37, the HOME NOT POSSIBLE error (M64=69) will
appear if bits# 2 and 3 of parameter K58 are equal to 0.
