NOTE
●
When initiating spindle indexing during spindle reverse, ensure that
the SINV input is ON while the spindle indexing request input
is ON.
“ When the input is turned ON to perform incremental spindle
indexing with the SINV input turned ON, the input pro-
vides incrementing in reverse direction.
“ Spindle indexing operations are not performed during interpolation
pulse output generation.
Be sure that the pulse count resulting from the increment command
does not exceed 1024.
Spindle indexing is performed with the phase C pulse (1 pulse/rev)
edge regarded as the reference pulse. Therefore, if the phase C
pulse has a certain width, the index position obtained from
direction spindle indexing differs by the phase C pulse width from that
obtained from reverse-direction spindle indexing.
