●
The spindle stop verification timer counting after verifying that the spindle rotating
speed for stop verification (# 1225) is reached. If the spindle rotating speed deviates from
the stop verification rotating speed during timer counting, the count is reset. Counting
restarts when the stop verification rotating speed prevails again, That is, the rotating
speed must not be higher than that specified during stop verification timer operation.
