We have developed a custom solution for model UCM-AC005-0013-E14W-ARW, based on a compact multiturn absolute encoder platform with SSI communication, a 58 mm clamping flange, and a Ø14 mm blind hollow shaft. This configuration is intended for installations that require reliable multiturn absolute position feedback with a hollow-shaft mounting structure, while keeping the electrical interface simple and stable. The platform provides 13-bit singleturn + 12-bit multiturn resolution with Gray-code output, suitable for direct controller-side SSI acquisition without moving to a fieldbus architecture. Typical production lead time: 15 working days.

Wiring and Installation Notes
This model uses an SSI interface with RS485 output driver, so signal stability depends more on wiring quality than on the encoder itself. In practice, unstable data transmission is more often caused by shielding discontinuity, improper cable routing, or grounding issues than by encoder failure. The clock and data pairs should be routed separately from inverter output cables and motor power lines, with shielding kept continuous along the full cable path.
The encoder supports typical SSI clock ranges, but higher clock rates are not always beneficial. In longer cable runs or noisy environments, reducing the clock frequency often improves signal reliability more effectively than additional filtering. The SET and direction control inputs should be tied to a defined logic level when unused, since floating control signals can lead to unstable counting direction or unexpected position shifts.
Mechanically, the Ø14 mm blind hollow shaft requires controlled installation to avoid radial stress and excessive clamping force. Hollow-shaft designs simplify mounting but are more sensitive to alignment and shaft condition than solid-shaft versions. In practical installations, shaft misalignment or uneven clamping is usually a more common source of long-term instability than electrical mismatch.
Application and Integration Notes
This configuration is typically used in compact automation systems, shaft-mounted drive assemblies, and positioning units where multiturn absolute feedback is required but space is limited and hollow-shaft mounting is preferred. Its practical value lies in combining SSI-based absolute position feedback with a direct shaft installation structure, reducing the need for couplings and mechanical adaptation.
Compared with fieldbus encoders, this model simplifies integration at the control level while maintaining stable position feedback, provided that wiring and grounding are properly managed. In practice, it is selected when a simple and deterministic SSI interface is sufficient, and when introducing fieldbus communication would add unnecessary system complexity.
