Pulse Output Function (CPM1A Only) Section 1-4
1-4 Pulse Output Function (CPM1A Only)
The CPM1A PCs with transistor outputs have a pulse output function capable
of outputting a pulse of 20 Hz to 2 kHz (single-phase). Either IR 01000 or
IR 01001 can be selected for pulse output, and the pulse output can be set to
either the continuous mode, under which the output can be stopped by an
instruction, or the independent mode, under which the output is stopped after
a preset number of pulses (1 to 16,777,215).
Refer to the CPM1A Operation Manual for details on hardware connections to
output points and ports.
Note 1. The CPM1A uses a single-phase pulse output. The control signal for the
direction of rotation (CW/CCW) for the motor driver must be written in the
program.
2. Be sure to use a CPU Unit with transistor outputs.

Pulses are output at the specified frequency until stopped.
Pulse output is stopped automatically when the specified
number of pulses has been output.
