Zero Energy State

In this state, all axes are completely disabled, and energy to all axes is blocked or stopped.

CNC benders designed by SMT Industries enter a true ZERO ENGERY STATE when an operator steps on the safety mat. We refer to this as the Safe Mode Cycle Hold state. It is only enabled using the safety mat or safety scanners.

With the exception of the chuck close output, no axis or valve can move when in this state.

Many benders in the industry do not enter a zero energy state in this condition. This means that that the dies and axes are being held in position by the servo controller. While this may be convenient for the control developers, it is, in our opinion, not a safe practice for operators.
