Product Overview
The Omron CK3W-AX1515N is a 4-axis interface unit for the CK3M and CK5M Programmable Multi-Axis Controllers, manufactured by Omron Corporation. Hengyixin Automation stocks this controller option board in Xiamen and ships within 3-5 business days to most Asian, European, and North American ports.
The unit provides four independent motion channels with True DAC analogue voltage output for commanding analogue-input servo drives. Each channel outputs two analogue points (DACA and DACB) plus a line-driver pulse stream up to 10 MHz. Encoder inputs accept 5 V differential line-receiver signals from quadrature, pulse, or serial encoders up to 10 MHz, with a 5 VDC 500 mA per-channel encoder power supply.
The unit carries 16 general-purpose NPN digital inputs and 16 NPN outputs for flags, limits, and amp enable, plus 4 dedicated flag inputs per channel (HOME, PLIM, NLIM, USER). Power consumption is 4.5 W on 5 VDC and 12.5 W on 24 VDC. The CK3W-AX1515P sibling swaps NPN for PNP digital I/O on the same True DAC stage. The CK3M-CPU111 is the matching controller.
Key Features
- CK3W 4-axis interface unit for CK3M / CK5M Programmable Multi-Axis Controllers, True DAC analogue voltage output
- 4 channels per unit, dual DAC outputs per channel (DACA + DACB), 10 MHz line-driver pulse stream for stepper drives
- 5 V differential line-receiver encoder inputs up to 10 MHz for quadrature, pulse, or serial encoders, 5 VDC 500 mA per channel
- 16 general-purpose NPN digital inputs, 16 NPN outputs, 4 dedicated flag inputs per channel (HOME, PLIM, NLIM, USER)
- SKU: CK3W-AX1515N
- Series: Omron CK3W axis interface unit on the CK3M / CK5M Programmable Multi-Axis Controller platform
- I/O: 16 I/O
Best-Fit Applications
- Multi-axis contouring on a CNC milling machine where True DAC analogue output drives analogue-input servo drives and avoids pulse-train quantisation noise
- High-speed web synchronisation on a slitter where the 4-axis module locks 3 slitting axes to the master encoder and reads NPN flags at 10 MHz
- Spare replacement on a CK3M motion rack where the existing axis module has failed and the existing CK3M-CPU111 must keep driving the same 4 servos
Buying Checklist
- Pick the CK3W-AX1515N for a 4-axis CK3W interface with True DAC analogue output and NPN flags on a CK3M / CK5M rack.
- Pick the CK3W-AX1515P instead when the cabinet needs PNP digital flags on the same 4-axis True DAC analogue stage.
- Pick the CK3W-PD048 instead when the rack needs an extra 48 W DIN-rail power supply to feed additional CK3W modules.

FAQ for CK3W-AX1515N
What is the Omron CK3W-AX1515N used for?
It is the CK3W 4-axis interface unit for the CK3M and CK5M Programmable Multi-Axis Controllers. It drives up to 4 servo or stepper axes with True DAC analogue or 10 MHz pulse commands and reads 5 V line-receiver encoders at 10 MHz on the same module.
CK3W-AX1515N vs CK3W-AX1515P - what is the difference?
Both are 4-axis interface units with True DAC analogue output. The N suffix is NPN digital I/O; the P suffix is PNP digital I/O. Pick the N for Japanese-style NPN flags and the P for European-style PNP flags. The analogue output stage is identical.
How many axes can the CK3W-AX1515N control?
Up to 4 axes per unit. Multiple CK3W-AX1515N modules chain on the same backplane to control more axes - the actual axis count depends on the CK3M or CK5M CPU's motion-cycle budget. The CK3M-CPU111 is the most common host for this unit.
Does the CK3W-AX1515N need a CK3M controller?
Yes. The CK3W-AX1515N is an axis interface module only and must live on the same backplane as a CK3M-CPU1_1 or CK5M-CPU1_1 controller. The controller runs the Power PMAC motion engine; the CK3W-AX1515N handles the analogue and pulse I/O to the drives.
