6-28 Application Examples
The following is a brief description of the application.
•
The Initial Outputs (M0:e.3/8-15) are reset to 0. Therefore, the
brake is enabled (the clutch is disengaged) and the cutter is
retracted.
•
The user program starts the motor. The encoder begins to send
pulses to the module.
•
After 100 counts, the module releases the brake (O:1/2), which
engages the clutch.
•
At count 150, the high-speed motor output (O:1/1) is energized.
•
At count 14000, the high-speed motor output (O:1/1) is
de-energized.
•
At count 18000, the brake is enabled (which disables the clutch)
and the cutter is energized.
•
At count 19000, the cutter is de-energized and the sequencer
rolls over. The process repeats, as indicated below by the repeat
point.
