High-speed Counter/Pulse Output Instructions
Section 3-21
Example
When CIO 000000 turns ON in the following programming example,
ORG(889) starts an origin return operation for pulse output 0 by outputting
pulses using the CW/CCW method. According to the PLC Setup, the initial
speed is 100 pps, the target speed is 200 pps, and the acceleration and
deceleration rates are 50 Hz/4 ms.
The PLC Setup parameters are as follows:
3-21-10 PULSE WITH VARIABLE DUTY FACTOR: PWM(891) (CJ1M-CPU21/
22/23 Only)
Purpose
PWM(891) is used to output pulses with the specified duty factor from the
specified port.
This instruction is supported by CJ1M-CPU21/22/23 CPU Units only.
