AMG11S25H1024 SSI Encoder with HTL 1024 Pulse Output

For AMG11S25H1024, EncoderWorks can provide a custom compatible replacement solution for SSI absolute multiturn feedback systems where the key checks are 25-bit SSI position reading, HTL 1024-pulse incremental output, K1/K2 phase relationship, and ø11 mm solid-shaft alignment. This version must not be mixed with the H2048 variant, because the absolute SSI position may match while the drive or controller still fails on speed feedback, pulse scaling, or direction supervision. Typical production lead time: 15 working days.

This model belongs to the AMG 11 absolute encoder series with EURO flange B10 and ø11 mm solid shaft. In the AMG11S25H1024 configuration, the main interface is SSI, the absolute share is 13-bit singleturn plus 12-bit multiturn, and the additional output is HTL level with 1024 pulses. Replacement work must verify both feedback paths together: SSI clock/data timing, Gray-code interpretation, multiturn scaling, HTL voltage level, K1/K2 phase, pulse count, cable shielding, and coupling load.

System Limits

The main system limit is dual-feedback matching. The controller may use SSI for absolute position recovery while using HTL pulses for speed feedback, direction monitoring, or motion supervision. If the replacement matches the SSI data but outputs the wrong pulse count, the machine may home correctly but report speed or following-error faults during motion.

The second limit is SSI frame and scaling. This model combines 8192 steps per revolution with 4096 revolutions, so the controller must read the correct SSI word structure, clock timing, and wait period. Wrong timing or Gray-code interpretation can create shifted or offset absolute position data.

The mechanical limit is the ø11 mm solid shaft and EURO flange B10 mounting. Coupling misalignment, axial preload, or radial force can shorten bearing life. Shield grounding and cable routing should also be checked because SSI clock/data pairs and HTL pulse channels can both be affected by inverter or motor noise.

Wiring & Installation

Before removing the existing encoder, record the SSI clock/data wiring, controller word length, HTL pulse input wiring, K1/K2 direction logic, supply voltage, shield connection, and mechanical zero position. The replacement should be checked against both the absolute SSI input and the incremental HTL input configuration.

After installation, confirm stable SSI position reading first. Then rotate the shaft and verify HTL 1024-pulse scaling, K1/K2 90° phase relationship, direction trend, and speed feedback under real machine conditions.

Custom Compatible Solution

EncoderWorks can configure the replacement around the installed SSI and HTL feedback system:

• Match SSI clock/data behavior, 25-bit absolute word structure, Gray-code reading, and controller-side sampling
• Verify HTL 1024-pulse output, K1/K2 phase relationship, direction trend, and incremental input compatibility
• Adapt the EURO flange B10, ø11 mm solid shaft, connection format, and mechanical mounting requirement
• Review shielding, cable routing, SSI receiver margin, HTL input threshold, and shaft coupling load
