Counter Reset Control
Reset Mode (bits 5,6,7) allows you to select the Accumulated Counter
reset conditions. If the pulse counter is reset, the rate calculation is not
affected. Bit 5 enables the Z reset, Bit 6 enables the limit switch reset,
and bit 7 enables the Soft Reset. The counter can be reset from any
combination of the Z input, LS input, or Soft Reset bit (M0:e.1/4).
In the Sequencer Mode, you can reset the sequencer to the Initial
Output pattern (M0:e.3/8-15) using the Sequencer Reset bit (M0:e.1/0).
The three bits can be set as follows:
Reset Mode - bits 5, 6, 7
