Robot Controller Backup Power Solution – Yaskawa JZNC-YPS21-E CPS-520F2 | DX200 / MP300 / MP350 Series
Where This Product Is Used
The Yaskawa JZNC-YPS21-E (CPS-520F2, P/N 50999-2922R08) is the OEM backup battery unit designed for Yaskawa’s DX200 robot controller platform and the MP300 / MP350 machine controller series. It is deployed across high-demand industrial environments where uninterrupted memory retention is mission-critical:
- Automotive body-shop welding lines – protects teach-pendant programs and weld schedules during planned shutdowns or power faults.
- Semiconductor & electronics assembly – preserves motion profiles and I/O mapping in cleanroom robot cells.
- Food & beverage packaging lines – maintains recipe data and conveyor synchronisation parameters across shift changes.
- Palletising & material-handling systems – retains coordinate offsets and payload settings for multi-axis gantry robots.
- Machine tool & CNC integration – backs up MP300/MP350 motion programs and axis calibration data.

Why Engineers Specify This Model
- OEM-exact replacement – drop-in fit with no firmware changes or parameter re-entry required.
- Memory retention on power loss – safeguards SRAM-stored programs, encoder absolute positions, and system parameters.
- Proven service life – Yaskawa recommends periodic replacement as part of DX200 preventive maintenance schedules, making this a planned-maintenance consumable.
- Broad controller compatibility – a single SKU covers DX200, MP300, and MP350 platforms, simplifying spare-parts inventory.
- Reduces unplanned downtime – a failed backup battery is one of the most common causes of “memory lost” alarms on DX200 systems; proactive replacement eliminates this failure mode.

Application-Specific FAQ
Q: How do I know my DX200 battery needs replacement?
A: The DX200 controller will display alarm code 4107 – Battery Voltage Low or 4108 – Battery Voltage Fault. Yaskawa also recommends proactive replacement every 3–5 years regardless of alarm status.
Q: Will I lose my robot programs when replacing the battery?
A: Yes, if the controller is powered off during replacement. Always back up programs to a USB or PC via the DX200 teach pendant before swapping the battery.
Q: Is JZNC-YPS21-E compatible with DX100 controllers?
A: No. The JZNC-YPS21-E is specific to DX200, MP300, and MP350. For DX100, a different battery unit is required – contact us for the correct part number.
Q: Can I order a refurbished unit to reduce cost?
A: Yes. Refurbished units are available at a reduced price and carry a 6-month warranty. Specify “refurbished” in your inquiry.
Q: What is the lead time for out-of-stock units?
A: Typical lead time from Yaskawa or authorised distributors is 4–8 weeks. We maintain safety stock to minimise this – contact us for current availability.
