Product Overview
The Omron CK3M-CPU111 is a programmable multi-axis motion controller CPU from the CK3M series, manufactured by Omron Corporation. Hengyixin Automation stocks this controller in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The CPU ships with 1 GB of RAM and 1 GB of built-in flash on a dual-core 1 GHz processor. Two Ethernet sockets expose one EtherCAT port for up to 4 servo axes and one EtherNet/IP port for upstream controllers and HMIs. Up to four CK3W-AX axis interface units chain on the right side for analog or pulse encoder feedback.
Servo cycle runs down to 25 microseconds across 5 axes for high-precision machining and nano-scale control. Programming is in Power PMAC IDE using PMAC motion language and standard IEC 61131-3 languages. The CK3M-CPU101 sibling drops EtherCAT for sequence-only use; the CK3M-CPU121 extends to 8 servo axes for larger machines.
Key Features
- CK3M multi-axis motion controller CPU, 1 GB RAM / 1 GB flash, dual-core 1 GHz processor
- 1 EtherCAT port (RJ45) for up to 4 servo axes + 1 EtherNet/IP port (RJ45) for upstream PLC / HMI
- Up to 4 CK3W-AX axis interface units chain on the right for analog / pulse encoder feedback
- 25 us / 5 axes servo cycle, Power PMAC IDE programming, IEC 61131-3 compatible
- SKU: CK3M-CPU111
- Series: Omron CK3M-series programmable multi-axis motion controller
- Voltage: 24 VDC
Best-Fit Applications
- High-precision CNC milling retrofit where 4 EtherCAT servos drive X / Y / Z and spindle axes with 25 us servo cycle for surface finish control
- Multi-axis packaging machine where the CK3M runs synchronized cutting, sealing and film-feed motion alongside a host NJ/NX PLC over EtherNet/IP
- Spare replacement on a wire-bonding or pick-and-place tool where the existing CK3M-CPU101 must be upgraded to add EtherCAT servo axes
Buying Checklist
- Pick the CK3M-CPU111 for a CK3M motion controller with 4 EtherCAT servo axes and built-in EtherCAT + EtherNet/IP on one body.
- Pick the CK3M-CPU101 instead when the cell needs sequence control only and no EtherCAT servo motion.
- Pick the CK3M-CPU121 instead when the machine needs 8 or more servo axes for a larger press or converting line.

FAQ for CK3M-CPU111
What is the Omron CK3M-CPU111 used for?
It is a multi-axis motion controller CPU for high-precision machines like CNC, packaging, and converting equipment. Four EtherCAT servo axes run on a 25 us / 5 axes cycle, with Power PMAC IDE for motion programming.
Does the CK3M-CPU111 have EtherNet/IP?
Yes. One EtherNet/IP port sits alongside the EtherCAT port for upstream NJ / NX PLCs, NA HMIs, and SCADA. EtherNet/IP and EtherCAT are two separate RJ45 sockets on the front.
CK3M-CPU111 vs CK3M-CPU101 - what is the difference?
The CK3M-CPU111 adds an EtherCAT port for up to 4 servo axes. The CK3M-CPU101 has no EtherCAT and is for I/O and sequence control only. Memory, processor, and EtherNet/IP port are identical between the two.
How many CK3W-AX axis interface units can the CK3M-CPU111 hold?
Up to 2 CK3W-AX[] units chain on the right side, ending with a CK3W-TER11 cover. The CK3W-AX1515N adds 4 analog inputs, the CK3W-AX1515P adds 4 pulse encoder inputs.
What software programs the CK3M-CPU111?
Power PMAC IDE, Omron's PMAC-based motion development environment. It supports the PMAC motion scripting language plus standard IEC 61131-3 languages (ladder, structured text, function block) for sequence logic.
