Check whether this subroutine complies with the relevant safety requirements or not.
Subroutine 33 handles emergency stop. Pressing down the Emergency Stop button produces an emergency stop alarm and
disables the drive enable signal (DB380x.DBX2.1). If you want to clear the emergency stop alarm, you must first release the
Emergency Stop button and then press the
key on the MCP.
This subroutine activates the alarm below:
Alarm 700016: DRIVE NOT READY
Local variable definition
Inputs
E_KEY BOOL Emergency stop key (NC)
Any one of the hardware limit switches is active (NO)

This input can come from signal OVlmt of subroutine 40, and triggers emergency stop when the hardware limit appears.
Before the drive system disables the control enable signal, the PLC detects the spindle stop signal from NCK to ensure
that the spindle has stopped.
NC being in the cyclic state and able to enable the drive
