Frequently Asked Questions (FAQ)

• Q: Does FX1N-40MT-001 require a backup battery for program retention?
  A: No. The program stores in built-in EEPROM. No battery needed.
• Q: What is the maximum expansion I/O for this PLC?
  A: Up to 128 total I/O points when combining with expansion units.
• Q: Can I use this unit for stepper motor control?
  A: Yes. The built-in 100kHz pulse output supports stepper drives directly.
• Q: What software programs this PLC?
  A: Use Mitsubishi GX Works2 or GX Developer (ladder logic).
• Q: How long does the capacitor keep data last?
  A: After 30 minutes of power-on, the capacitor holds data for 10 days.
