I. Component-by-component disassembly of the model (Key points: SE, EN1 + EN2, NN safety, no FW)

CSH01.1C: CSH high-end series, hardware V1, C = scalable single-axis control card.

SE: SERCOS II master station communication (old model SERCOS, not S3 = SERCOS III).

EN1: Main encoder = EnDat 2.1 (high-precision digital encoder).

EN2: Second encoder = EnDat 2.1 (dual encoder, motor + external feedback).

NNN: No expansion module (no analog quantity, memory card, etc.).

NN: No safety function (neither S1 basic safety nor S2 STO/SIL3).

S: Single-line LED + 4-key standard local operation panel.

NN: No additional optional items.

(SFW): The model does not contain FW, the firmware is not pre-installed at the factory, and it must be ordered separately for burning to run.

II. Core parameters (Dual EnDat + Bare Board Basic Version)

Basic parameters

Number of controlled axes: single-axis high-performance servo.

Control cycle: current loop 62.5μs; speed loop 125μs; position loop 250μs.

Power supply: DC24V ± 10%, power consumption approximately 7.5–10W.

Board I/O: 7DI/3DI/O/1 relay; 1AI/2AO (basic).

Communication: SERCOS II, RS232, service Ethernet.

Safety: NN = no safety function (no STO, no SIL level).

Size/Weight: 241×103×49.5mm, approximately 0.85kg.

Adapter power unit: HCS02/HCS03/HCS04.

Encoder interface

EN1 + EN2 (Dual EnDat 2.1): dual high-precision digital encoders, supporting motor + external optical encoder full closed-loop.

III. Configuration highlights (Dual encoders + no safety + no firmware)

EN1 + EN2 = Dual EnDat full closed-loop

High positioning accuracy, suitable for scenarios requiring dual feedback such as precision machine tools, semiconductor equipment, etc.

SE = SERCOS II (compatible with old systems)

Used to replace old SERCOS II devices, does not support µs-level multi-axis synchronization of SERCOS III.

NN = no safety function

No STO, no SIL certification, only for ordinary safety-level equipment, the cost is the lowest.

No FW = must purchase firmware separately

The model does not contain FW, power-on without program, cannot run, it must be ordered separately for the FWA-INDRV-xxx firmware package.

IV. Application scenarios

High-precision single-axis full closed-loop: precision positioning table, CNC machine tools (dual EnDat feedback).

Upgrade of old equipment SERCOS II: Replace the old CSH/CSB control card, retain the original bus.

Budget-sensitive, no safety requirements: ordinary automation equipment, no STO/SIL3 required.

Requires custom firmware: scenarios where users need to burn a specific version of firmware.
