I. Component-by-component disassembly of the model (key differences in EN2)

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

S3: SERCOS III master station communication, high-speed real-time bus (multi-axis synchronization at µs level).

EN2: First encoder interface = EnDat 2.1/1Vpp/TTL universal type (different from the Rockwell-specific type in EN1).

NNN: No second encoder interface (EN2 is empty).

NNN: No expansion module (analog output, encoder output, etc.).

S2: Safety function STO (Safe Torque Off), SIL3/Cat.3/PLe level.

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

NN: No other additional options.

FW: Factory pre-installed complete firmware, ready for debugging and operation upon power-on.

II. Core parameters (CSH01.1C common + EN2 exclusive)

Basic parameters

Number of control 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.

Onboard I/O: 7DI/3DI/O/1 relay; 1AI/2AO.

Communication: SERCOS III, RS232, service Ethernet.

EN2 exclusive encoder

Signal type: EnDat 2.1 (digital), 1Vpp (analog), TTL (square wave).

Compatibility: universal encoder (not Rockwell-specific), compatible with most mainstream servo motors.

Power supply: DC11.6V/300mA.

III. Key configuration points (core differences between EN2 and EN1)

EN2 = universal encoder interface

Supports EnDat 2.1/1Vpp/TTL, compatible with Siemens, Fanuc, etc. universal encoder motors;

EN1 = Rockwell-specific (HSF/RSF), only compatible with Rockwell self-produced motors.

S3 (SERCOS III)

High multi-axis synchronization accuracy, suitable for machine tools, packaging, printing, etc. high-speed linkage equipment.

S2 (STO safety)

Standard safety torque off, meets mechanical safety standards, no additional safety module required.

FW (pre-installed firmware)

Factory pre-programmed firmware, ready for use upon power-on, saving engineering time.

IV. Application scenarios
