OCD-PPA1B-0013-B100-CAW Parallel Encoder with 13-Bit Binary Output

OCD-PPA1B-0013-B100-CAW should be handled as a 13-bit binary parallel singleturn replacement, where EncoderWorks can configure a custom compatible solution only if the Bit 1–13 wiring, latch timing, DIR input state, push-pull signal level, axial cable shielding, and ø10 mm blind-hollow shaft fit remain aligned with the existing controller. The main failure boundary is not a complete signal loss, but a clean parallel input set decoded with the wrong bit order, code type, or sampling timing. Typical production lead time: 15 working days.

This configuration is used where a controller reads absolute singleturn position directly through parallel inputs instead of SSI, Profibus, PROFINET, EtherNet/IP, or incremental A/B/Z signals. The encoder combines 13-bit singleturn resolution, binary output code, push-pull driver behavior, a ø58 mm blind-hollow flange, ø10 mm blind-hollow shaft, and a 1 m axial PVC cable. Replacement work should focus on Bit 1–13 assignment, binary value interpretation, controller input threshold, latch response, DIR logic, cable-core identification, shaft insertion depth, clamp force, and shield continuity.

System Limits

The first system limit is 13-bit binary mapping. Bit 1 through Bit 13 must remain connected to the same controller inputs as the original encoder. If one bit is shifted, inverted, or assigned to the wrong input, the PLC may receive a stable but incorrect absolute position value.

The second limit is sampling and code interpretation. This model uses binary code, not Gray code. If the controller expects Gray-code conversion, or if the latch input does not match the controller scan window, the position value can jump during motion, startup, or reference checks.

The mechanical limit is the ø10 mm blind-hollow shaft with axial cable exit. Shaft insertion depth, clamp force, static misalignment, dynamic misalignment, cable bend radius, and cable strain must be controlled. A forced bore fit or poor cable routing can create bearing load, repeatability drift, or intermittent feedback faults under vibration.

Wiring & Installation

Before replacement, record the axial cable wiring for Bit 1–13, Latch, DIR, power supply, GND, and shield. Confirm that the controller reads binary code directly, and verify whether the latch input is fixed, pulsed, or synchronized with the controller scan cycle.

During installation, confirm the ø10 mm blind-hollow fit without forcing the shaft. Keep the encoder body square to the mounting face, control clamp preload, route the axial cable away from inverter and motor power wiring, maintain shield continuity into the cabinet, and avoid ground loops between the encoder housing, machine frame, and controller earth. After startup, verify zero/reference value, counting direction, bit transition stability, latch response, and repeatability over several machine cycles.

Custom Compatible Solution

EncoderWorks can configure the replacement around the installed controller and mechanical interface:

• Match 13-bit singleturn parallel binary position output and push-pull driver behavior
• Preserve Bit 1–13 mapping, latch input timing, DIR logic, supply range, and controller input compatibility
• Adapt the ø58 mm blind-hollow flange, ø10 mm blind-hollow shaft, clamp interface, and axial 1 m cable layout
• Review cable shielding, grounding, EMC routing, binary decoding, input threshold, shaft fit, clamp preload, and cable bend radius
