CPM1A Pulse Output Functions

Pulse output
(single-phase output)
IR 01000 or IR 01001
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 (W317) for details on hardware connec-
tions to output points and ports.
Continuous mode
Independent mode
Stepping motor
CW/CCW control output
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.
