4. Product Introduction
The Yaskawa CPS-150F is the control power supply unit used in Motoman NX100 and XRC series robot controllers. It converts 200–230 V AC incoming power into the regulated 5 V and 24 V DC rails required by the I/O contactor unit and the programming pendant.
Maintenance teams replace this unit when control power is lost, the pendant fails to power up, or internal DC rails become unstable. The module also provides the control power on/off input function. As a discontinued part, available units are New Surplus or fully tested residual stock.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No control power / pendant dead | CPS-150F failure or input power missing | ✅ High | Measure 200–230 V AC at input terminals; check output 5 V / 24 V rails | Verify incoming AC first, then test DC outputs |
| Intermittent power loss | Loose connectors or internal component degradation | ✅ High | Inspect all cable connections; monitor voltage under load | Reseat connectors and check for heat damage |
| Control power will not turn on | On/off input circuit or external switch fault | ✅ Medium | Check control power enable signal wiring | Verify external enable circuit before replacing PSU |
| Overheating or burning smell | Overload or failed internal components | ✅ High | Check load on 5 V / 24 V rails; inspect for swollen capacitors | Replace unit; do not continue operation |
| Robot controller boots but I/O unresponsive | 24 V rail problem | ✅ High | Measure 24 V at JZNC-XIU01 connector | Confirm 24 V delivery to contactor unit |
If the problem remains unresolved, record input/output voltages and LED status before contacting support.

6. Frequently Asked Questions (FAQ)
Q: Which robot controllers use the CPS-150F?
A: It is used primarily in Yaskawa Motoman NX100 and XRC series controllers. Confirm the exact controller model and revision before ordering.
Q: What voltages does the CPS-150F supply?
A: It converts 200–230 V AC into regulated DC 5 V and 24 V for the I/O contactor unit (JZNC-XIU01) and the programming pendant.
Q: Is this unit still in production?
A: No. The CPS-150F is a discontinued part. Current stock consists of New Surplus or carefully tested residual units.
Q: Can I substitute a generic 24 V power supply?
A: Not recommended. The provides both 5 V and 24 V rails plus the specific control power on/off interface required by the Motoman controller architecture. A generic supply will not provide full compatibility.
Q: How is the unit mounted?
A: It is designed for rack mounting inside the controller cabinet. Removal requires disconnecting cables and removing the retaining screws on the upper and lower sides.
Q: Why is the price lower than a new Yaskawa power supply?
A: This is a discontinued product sold as New Surplus or tested residual stock. Pricing reflects remaining inventory rather than current production cost. All units are functionally verified before shipment. Standard warranty is typically 12 months.
Q: What should I check before replacing the ?
A: Verify incoming 200–230 V AC is present and stable, inspect all output cables for damage, and confirm the control power enable signal is correct. Many “power supply” faults are actually external wiring or enable circuit issues.
