Safety door issue
« on: September 18, 2011, 06:30:21 PM »
Good night,

In a totaly closed lathe, with a sliding door with a solenoid, during a cycle run, the user cannot open the door as it is closed by the solenoid.
With the machine stoped (non cycle), the user is able to open the door and the following should happen:

1) Not possible to jog the machine. I do not want to disable the servo drives as in Mach the axis values would change, I want that Mach disables movement until door is closed - it is possible? this is, there is a why that jog and outputs (water pump for example) are not enable while the door is opened?
2) Not be able to start a cycle. This is ok to implement.

Thank you and greatings.

MACH has a door safety input. As long as the door remains open MACH will not move. BUT that is a software solution and MAY not meet  some safety requirements.

Mach will still jog, it is code that will not run with that input actiive.
It could be done in a macropump or brain by watching that input (input 1)  and turning off the Jog control as well.

Agree on safety side of things though, fine for someone to do for themselves but for employees may not be so good.
