Hi,
I am in the process of setting up a plc to output a 20khz with a duty cycle of 20%. I set up the ladder and setup the hardware for pwm. The duty cycle was setup as a MI and I set it to 200 for 20 Percent. My problem is figuring out the proper way to set up the frequency? I tried different MI for the frequency but cant get the signal to output at 20000hz. I am able to turn the pwm on and off but having difficulty acheiving higher frequencys.
I have V570 with V200-18-E3xb snap in I/O. I set up the dip switches for NPN. Can I get a diagram or just the proper steps for setting this up. Ive checked the manual and the help topics but none of them show clearly how to set this up. I am new to this software, but fluent in ladderlogic.
Thanks,
Ken
