# 1 CTLSTP The method to stop spindle motor at safety speed over alarm is:
0: free-running stop.
1: controlled stop. (After SSTA=1, excitation is off.)
Set the method to stop spindle motor at safety speed over alarm(SP757, SP9069).
In case that this parameter is set to “0”, safety speed over alarm causes the spindle
motor to free-running stop.
In case that this paremeter is set to “1”, safety speed over alarm causes the spindle
motor to controlled stop. And then, the excitation of the spindle motor becomes off
after SSTA(speed zero detection signal) becomes “1”.
NOTE
1 Even if controlled stop is selected (CTLSTP=1), the excitation of
the spindle motor becomes off and the spindle motor rotates
freely in case that another SPM alarm occurs during deceleration.

- Page 21. Outline Conventionally, when safety speed over alarm (exceeding Dual Check Safety limiting spindle speed) occurs, the excitation of the spindle motor becomes off immediately and the spindle rotates freely. It may take much time for the spindle to come to a stop by friction. In order to avoid such
