I. Detailed Explanation of Model Numbers

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).

EN1: First encoder interface (HSF/RSF Rockwell-specific), compatible with its servo motors.

NNN: No second encoder (EN2).

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, no additional ordering / flashing required.

II. Core Parameters (Common for CSH01.1C)

Number of control axes: Single-axis high-performance servo.

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

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

On-board I/O: 7DI / 3DI/O / 1 relay; 1AI / 2AO.

Communication: SERCOS III, RS232, service Ethernet.

Encoder: EN1 (HSF/RSF); non-general Hiperface/1Vpp/TTL.

Safety: S2 = STO (SIL3).

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

Compatible power unit: HCS02 / HCS03 / HCS04.

III. Key Configuration Points (Compared with FW-less Version)

S3 (SERCOS III)

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

EN1 Encoder

Only applicable to Rockwell HSF/RSF dedicated encoders; general encoders require the ENS model.

S2 (STO Safety)

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

FW (Pre-installed Firmware)

Different from the models without FW at the end: Factory pre-programmed firmware, can be debugged and operated upon power-on, saving engineering time.

IV. Application Scenarios

Multi-axis联动 CNC machine tools (SERCOS III bus synchronization).

Packaging / Printing / Textile high-speed synchronization + basic safety equipment.

Complementary Rockwell HSF/RSF encoder servo motors.
