CPU 1217C example output speed configurations
Note
The CPU 1217C can generate pulse outputs up to 1 MHz, using the onboard differential
outputs.
The examples below show four possible output speed combinations:
● Example 1: 4 - 1 MHz PTOs, no direction output
● Example 2: 1 - 1 MHz, 2 - 100 KHz, and 1 - 20 KHz PTOs, all with direction output
● Example 3: 4 - 200 KHz PTOs, no direction output
● Example 4: 2 - 100 KHz PTOs and 2 - 200 KHz PTOs, all with direction output
