FAQ – Small Indexing System Integration

What is a typical application for this small indexer drive?

It's ideal for compact machines like small CNC lathe tool changers, light-duty rotary index tables for assembly, or any device that needs to rotate to fixed, repeatable positions accurately.

How do I choose between single-phase and three-phase power?

Use three-phase if available for smoother input power. Single-phase is acceptable for this low power level and offers easier connection in facilities without three-phase at the machine.

Is programming the index positions complicated?

No. Using the RS-422 port with Mitsubishi setup software, you can easily define the number of positions (e.g., 4, 6, 8, 12) and the index angle for each, simplifying machine logic.

Does natural cooling require any special mounting?

Yes. For effective heat dissipation, mount it vertically on a flat metal panel as specified in the manual. Ensure adequate clearance around the unit and avoid mounting it above other heat-producing components.

Can I use the CC-Link network for more than just motion commands?

Yes. Over CC-Link, you can send index commands, monitor status (like "Position Reached"), and also read/write other drive parameters, centralizing control in your main PLC.
