PB3 =0: the hydraulic control function is disabled.
=1: the hydraulic control function is enabled.
z Function description
①
When the hydraulic control function is enabled, pressing can control HPST output to
start the hydraulic motor.
② In non-run, the spindle stop with the speed 0, pressing can disable HPST output.
③
When the hydraulic control function enables and the hydraulic motor is started, the system
alarm, at the time, the spindle cannot rotate.

z Function description (defined by standard PLC program)
When PB4 ① ＝ 1, SPB4 ＝ 0, CNC confirms that the safety door is closed as SAGT is connected
to 0V;
When PB4 ② ＝ 1, SPB4 ＝ 1, CNC confirms that the safety door is closed as SAGT is connected
to +24V;
In Auto mode, if CNC detects the safety door is open, alarm
③
is issued as cycle starts;
