402
[Classification] Output signal
[Function] This signal specifies that the spindle be clamped mechanically in a spindle
positioning sequence.
When this signal turns to 1, clamp the spindle on the machine (apply the
brakes or insert the pin).
[Output condition] Refer to the sequence (time chart) in this section.
[Classification] Input signal
[Function] This signal indicates that clamping the spindle is complete in response to
the spindle clamp signal SCLP.
Refer to 9.3 “Spindle Speed Control.”
