FAQ – Frequently Asked Questions
Q: What is the difference between FX1S-20MT-001 and FX1S-20MR-001?
A: MT means transistor output (sink type), suitable for high-speed switching and positioning. MR indicates relay output, better for pure AC loads but slower response. For motion control, always choose MT.
Q: Can I control a stepper motor directly with this PLC?
A: Yes. The MT model provides two 100 kHz pulse outputs (Y0, Y1). Use positioning instructions like PLSY, PLSV, or ZRN to drive stepper drivers without additional modules.
Q: Does the PLC support analog input without expansion?
A: No built-in analog channels. You can add an FX1N-2AD-BD or FX0N-3A analog expansion board/module for mixed analog I/O.
Q: What software do I need to program it?
A: MITSUBISHI GX Works2 (or GX Developer). Both support FX1S series. A USB-RS422 programming cable (SC-09) is required for PC connection.
Q: Is the power supply AC100-240V or DC24V?
A: For FX1S-20MT-001 the correct supply is 24V DC. Some FX1S variants come with AC power, but this specific model uses DC input. Check the rating label.
Q: How do I ensure long-term reliability in dusty environments?
A: Install in an IP54 or higher enclosure. The PLC itself is rated for industrial pollution degree 2. Regular inspection of terminal tightness is recommended every 6 months.
Q: Selection guide – which FX1S model fits my needs?
A: Choose FX1S-20MT-001 if you need 12 inputs/8 transistor outputs, high-speed positioning, compact size. For more I/O (up to 30), pick FX1S-30MT. For AC loads, relay type (MR) is better. Always confirm supply voltage: DC24V for MT-001.
Buying Guidance – Why FX1S-20MT-001?
- ✔ Cost-optimized for small machinery without sacrificing performance.
- ✔ Two independent 100kHz pulse outputs – built-in positioning eliminates extra modules.
- ✔ EEPROM memory – battery-free, program safe even after power loss.
- ✔ Ultra-compact footprint (75×75mm) fits in tight control cabinets.
- ✔ Global certifications (CE, UL) simplify export compliance.
