EncoderWorks can supply PSS58N-F2AAGR0BN-0013 as a custom compatible replacement solution where the PROFIBUS terminal wiring and 13-bit singleturn scaling must remain aligned with the installed controller. The failure boundary is defined by 8192 steps per revolution, address setting, bus termination, Bus In / Bus Out continuity, preset behavior, rotation direction, and the Ø12 mm recessed hollow-shaft fit. Typical production lead time: 15 working days.
This model is used as a singleturn absolute rotary encoder in PROFIBUS position systems where one revolution must be converted into a stable angular value. A compatible replacement must preserve the terminal-side bus path, binary position format, scaling relationship, and anti-rotation mounting method so the machine does not restart with a bus fault, angular offset, or bearing load problem.
System Limits
The first system boundary is the 13-bit singleturn scaling and PROFIBUS terminal relationship. PSS58N-F2AAGR0BN-0013 uses binary position data with 8192 angular steps per revolution, so the controller expects the same scaling value, rotation direction, preset behavior, address, device-class configuration, and diagnostic response. If the replacement is configured as a 16-bit unit, uses the wrong parameter length, has a duplicated address, reversed A/B data lines, incorrect termination, or mismatched preset handling, the result can be wrong angular position, proportional angle error, direction reversal, configuration error, communication loss, or data timeout. Terminal-side Bus In and Bus Out continuity are also part of the same boundary because an outgoing segment can be affected by the termination switch or field wiring error.
The second boundary is the Ø12 mm recessed hollow-shaft and terminal-cover installation. This version mounts directly onto the machine shaft and uses a removable terminal compartment, so bore fit, insertion depth, shaft concentricity, torque-rest position, radial cable exit, shield landing, cable strain relief, and cover sealing must be controlled together. Excessive shaft offset, rigid torque-rest preload, poor shield termination, terminal strain, or water and dust exposure at the cover can cause bearing stress, unstable bus exchange, signal dropout, ingress failure, or early mechanical damage even when the electronic configuration is correct.
Wiring & Installation
Before replacement, confirm the full installed model code, PROFIBUS address, terminal assignment, Bus In and Bus Out routing, controller device class, 13-bit singleturn scaling, preset use, rotation direction, diagnostic settings, and termination position in the bus segment. The “00” position in this singleturn code should not be treated as a multiturn value; the replacement boundary is the angular resolution and terminal-side bus behavior expected by the controller.
During installation, the Ø12 mm recessed hollow shaft should slide onto the machine shaft without forcing the encoder body into alignment. The torque rest should stop housing rotation while avoiding side load on the bearings. Keep PROFIBUS shield continuity through the terminal compartment, route bus wiring away from motor and brake cables, avoid sharp bending at the radial exit, and close the terminal cover so sealing, grounding, and cable strain relief remain stable during machine motion.
