The FX5-20PG-D is a 2-axis pulse train positioning module that lives in an FX5 rack. It runs on 24 V DC supply from the backplane and draws 165 mA, so it won't starve the bus if you're already loaded with I/O. The ON current threshold is 3 mA or more; the OFF current must be 1.7 mA or less — that's the signal window your stepper drive's opto-input needs to see. If you're getting missed steps, check the cable length and termination before blaming the module.

Frequently asked questions
What are the key electrical ratings of the FX5-20PG-D?
It operates on 24 V DC supply (+20%, -15%) and draws 165 mA from the backplane. The pulse outputs have a minimum ON current of 3 mA and a maximum OFF current of 1.7 mA.
Can the FX5-20PG-D be used as a drop-in replacement for the FX3S-20MR/ES?
No. The FX3S-20MR/ES is a compact PLC with relay outputs, not a positioning module. They serve completely different functions, form factors, and power supply requirements.
