Frequently Asked Questions
What's the advantage of CJ1M series?
Built-in pulse I/O for positioning (2-axis 100kHz), compact size, cost-effective for small machines. Ideal for applications requiring simple motion control without additional modules.
What motion control capabilities does this CPU have?
Built-in 2-axis 100kHz pulse output for stepper/servo control. Supports independent positioning, speed control. For interpolation or more axes, add CJ1W-NC position control units.
How many expansion units can I add?
Maximum 10 expansion units (I/O, analog, communication). Limited by CPU's I/O capacity (256 points max) and power budget.
Is CJ1M series still available?
CJ1M is approaching end-of-life. For new designs, consider CP2E or NX1P2 series. For existing CJ1M systems, contact Omron for migration path.
