In this state, all motion-controlled axes are completely disabled, and energy to all axes is blocked or stopped. CNC benders designed by SMT Industries enter a true ZERO ENERGY 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.
In fact, the only actuator that can be changed in this state by the operator is the CHUCK CLOSE/OPEN valve.
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.
