Spindle positioning is done at the rapid traverse rate specified by
parameter No. 1420, to which linear acceleration deceleration are applied.
Overrides of 100%, 50%, 25% and F0 (parameter No. 1421) are also
applied.
A specific M code (parameter no. 4961) must be set when the mode is
changed from spindle positioning to normal spindle rotation.
[Classification] Input signal
[Function] When this signal is 1, the CNC orients and positions the spindle.
[Classification] Output signal
[Function] This signal specifies that spindle mechanical clamping be released in a
spindle positioning sequence.
When this signal is output, unclamp the spindle on the machine (release
the brakes or extract the pin).
[Output condition] Refer to the sequence (time chart) in this section.
[Classification] Input signal
[Function] This signal indicates that unclamping the spindle is complete in response
to the spindle unclamp signal SUCLP.
