• Back to CNC Bender Software Updates

This new feature allows selected COMDEFs to run in the processlist without pausing during CYCLE HOLD. The reason for this new capability is that some customers require that their benders be equipped with palm buttons that must be held during any part of the bending with pinch-point motion.

For example, the Allen Bradley 800Z Zero Force Touch Buttons can be installed on the left and right side of control.

There are points in the cycle where it is necessary to grasp the part and open the dies to remove the part from the bender. However, removing hands from the touch buttons to remove the part puts the part into cycle hold. The commands that examine the RELEASE button and open the dies can be programmed to ignore CYCLE HOLD in order to open the dies in CYCLE HOLD.
<br Another benefit of this capability is that many commands that wait, illuminate, or set outputs without moving actuators can be working even during CYCLE HOLD. This speeds the process by letting the non-motion commands to continue to run.

The bend arm will always home before the carriage moves to the start position and the clamp closes for bending. This behavior ensures that the bend arm is returned to zero in case it has drifted outward slightly after the operator steps on the safety mat for loading the part.

This feature helps in push bending precision, and in reducing clamp bending.
