Pulse Output Function (CQM1 Only) Section 1-3
The following diagram shows the frequency of pulse outputs from port 1 as
the program is executed.
!Caution Be sure that the pulse frequency is within the motor’s self-starting frequency
range when starting and stopping the motor.
Example 3: PLS2(– –) The following example shows PLS2(––) used to output 100,000 CW pulses
from port 1. The frequency is accelerated to 10 kHz at approximately 500 Hz/
4 ms and decelerated at the same rate.
Five seconds after the CW pulses have been output, another PLS2(––)
instruction outputs 100,000 CCW pulses with the same settings.
The following diagram shows the frequency of pulse outputs from port 1 as
the program is executed.
