SPB4 =0: When SAGT is at low level (disconnect with +24V), the protection door is closed;
=1: When SAGT is at high level (connected with +24V), the protection door is closed;
SGSP =0: Spindle is disabled when the protection door is open;
=1: Spindle is not disabled when the protection door is open;

Function description (defined by standard PLC program)
① When PB4 ＝ 1, SPB4 ＝ 0, CNC confirms that the safety door is closed as SAGT is connected
to 0V;
② When PB4 ＝ 1, SPB4 ＝ 1, CNC confirms that the safety door is closed as SAGT is connected
to +24V;
③ In Auto mode, if CNC detects the safety door is open, alarm is issued as cycle starts;
④
In auto running, if CNC detects the safety door is open, the axis feed is held, and alarm is
issued by CNC;
⑤
The safety door detection function is only active in Auto mode;
