Battery Parameters: The clock data can be maintained with a 3V lithium battery, or run dynamically without a battery.
Delivery information typically includes delivery times, shipping methods, packaging, etc., which may vary depending on the seller and the location of purchase.
A: The FX5UJ CPU module has options with 24, 40, or 60 points, and the total control points can scale up to 256 points including both physical I/O and remote I/O points.
A: Yes. Transistor output models support positioning control for up to 3 axes, with a maximum output frequency pulse train of 200kpps.
A: Mitsubishi recommends using GX Works3 (version 1.080 or later) which supports structured programming using Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), and Sequential Function Chart (SFC) formats.
A: No, the program is retained in non-volatile memory and does not require a backup battery. A 3V lithium battery is optional for retaining clock data.
A: It is ideal for small to medium-scale automation equipment and production environments, such as packaging systems, textile machinery, and conveying systems.
