FAQ for CJ2M-CPU11
What's the difference between CJ2M-CPU11, CPU12, CPU13?
Program capacity: CPU11=5K, CPU12=10K, CPU13=20K steps. All have same I/O capacity (2560 points) and features. Choose based on program size requirements.
Can this CPU communicate over Ethernet?
CJ2M-CPU11 has USB only. For Ethernet, add CJ1W-ETN21 Ethernet unit or CJ1W-EIP21 EtherNet/IP unit to the CPU rack.
What motion control capabilities does this CPU have?
Built-in 2-axis 100kHz pulse output for stepper/servo control. For more axes or advanced motion, add CJ1W-NC position control units.
Is CJ2M series still available?
CJ2M is approaching end-of-life (some models). For new designs, consider NX1P2 series. For existing CJ2M systems, contact Omron for migration path.
