The M1200 DPS monitors input sensors to ensure that proper conditions are established (as far as material progression is concerned) before the die makes a hit. Up to 12 sensor inputs are monitored within user-programmed position dwells.

The position information comes from an Autotech resolver, such as the RL100. Each input can be monitored for a variety of events, such as rising edge, falling edge, position high, position low, or pulse events on input, within the programmed dwell. Absence of an event triggers a fault.
