IntLock
Dedicated input, protection signal input. If the machine needs
to be protected in a specific state (such as cover open), the
alarm signal is input to this port. This port can be enabled
and disabled. When this port is disabled, this signal is
neglected by the controller. If this port is enabled, the
machine is protected when the input is in high voltage or the
port is float. Once the alarm triggered, motion will be stopped
and the laser is switched off synchronously.
5
Ex-Run
Dedicated input. Extern start input. Usually for foot control
switch start the machine. Low level is valid.
When system is idle, if a low level signal is sent to this port,
machine will be start. If the machine is working, a low level
signal is sent to this port, machine will be stopped. Send
again, machine will go on working.
