Compatible Replacement & Equivalent Models
If the UDX5114-G3-2 is discontinued, out of stock, or cost-prohibitive, the following models offer functional equivalence or drop-in compatibility. Always verify motor wiring and step resolution settings before substitution.
- VEXTA UDX5128-G3-2 — Higher current rating variant in the same G3 series; pin-compatible, suitable for larger 5-phase motors
- VEXTA UDX5107-G3-2 — Lower current variant; suitable for lighter-load applications with the same AC100V input
- Oriental Motor CVD514-K — Next-generation 5-phase driver with enhanced microstepping; requires firmware/parameter reconfiguration
- Oriental Motor CVD528-K — Higher-output successor; compatible with most 5-phase motor wiring harnesses
- Leadshine 5-Phase Driver M542 — Third-party equivalent for cost-sensitive replacements; verify step pulse timing compatibility
Note: Cross-reference motor current ratings and connector pinouts before installation. Contact Konmask.com for verified compatibility confirmation.
Why Choose the Original VEXTA UDX5114-G3-2
- Proven OEM reliability — Used in production lines across Asia, Europe, and North America for 10+ years

Typical Applications
- Semiconductor wafer handling and inspection equipment
- PCB drilling and pick-and-place machines
- Medical imaging and laboratory automation
- Textile and packaging machinery
- Precision XY positioning stages
- Laser engraving and cutting systems
System Compatibility
The UDX5114-G3-2 accepts standard pulse/direction (PLS/DIR) signals and is compatible with the following control systems:
- Mitsubishi MELSEC PLC series (FX, Q, iQ-R) via pulse output modules
- Omron CJ/CS/NJ series with motion control units
- Siemens S7-1200 / S7-1500 with TO_PositioningAxis
- Keyence KV series with high-speed pulse output
- Standalone motion controllers (e.g., Galil, Parker)
- PC-based control via NI or Advantech motion cards
Selection Guide
Use the following criteria to confirm the UDX5114-G3-2 is the right driver for your application, or to select an appropriate alternative:
- Motor phase: Must be 5-phase — not compatible with 2-phase stepper motors
- Supply voltage: Confirm AC100V availability at the control cabinet; for AC200V systems, select the UDX5114-G3 (without -2 suffix)
- Motor current: UDX5114 supports up to 1.4 A/phase — match to your motor’s rated current
- Step resolution: Select microstepping ratio (full, half, 1/5, 1/10) based on required positioning accuracy
- Enclosure: Open-frame design — install in a sealed control panel (IP54 or higher recommended)
- Replacement scenario: If replacing a failed unit, photograph the existing wiring before removal and match connector types

Replacement & Compatibility FAQ
Q: Is the UDX5114-G3-2 the same as the UDX5114-G3?
A: No. The “-2” suffix denotes the AC100V input version. The UDX5114-G3 (without -2) is rated for AC200V. Using the wrong voltage version will damage the driver.
Q: Can I use a 2-phase driver as a replacement?
A: No. 5-phase motors require 5-phase drivers. A 2-phase driver cannot energize the 5-phase winding sequence correctly.
Q: What do the reference numbers TYPE 1651, 1651C2S, and CFL01.1-TP mean?
A: These are OEM-assigned part numbers used by machine builders to reference the UDX5114-G3-2 in their BOM. They are functionally identical to the VEXTA catalog number.
Q: Is the CVD514-K a direct drop-in replacement?
A: Electrically compatible, but the CVD514-K uses a different connector and parameter setup. Wiring adapter and parameter reconfiguration are required. Contact us for a migration guide.
Q: Do you offer testing before shipment?
A: Yes. Functional test reports are available for refurbished units upon request at no additional charge.
