Retract electrode after error

Save current system data for later electrode retraction

Description

When a die-sinking system is used, it is difficult for the user to extract an electrode out of the workpiece manually without damaging it after a power failure.

This control unit offers the option of signalling the CNC to save the current system data for later reuse with automatic retraction. This control unit should therefore be activated as soon as a power failure is detected and the CNC is shut down.
The data is saved on a positive edge and the control unit must be placed on hold until the status has been updated.
