I. Model Explanation in Detail

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

S3: SERCOS III master station communication interface, high-speed real-time bus, used for multi-axis synchronous control

EN1: First encoder interface (HSF/RSF dedicated), compatible with specific incremental / absolute value encoders

NNN: No second encoder interface (EN2 is vacant)

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

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

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

NN: No other additional options

(No firmware at the end): Factory does not pre-install firmware, needs to be ordered separately / rewritten

II. Core Parameters (Common to the same series)

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

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

Communication: SERCOS III, RS232 debugging port, service Ethernet

Encoder: EN1 (HSF/RSF); compatible with Hiperface/1Vpp/TTL (requires ENS)

Safety: S2 = STO (SIL3)

Size/Weight: 241×103×49.5mm, approximately 0.6–0.85kg

Compatible power units: HCS02, HCS03, HCS04

III. Configuration Points

S3 (SERCOS III)

Industrial real-time bus, high multi-axis synchronization accuracy (µs level), often used in multi-axis linkage equipment such as machine tools, packaging, and printing.

EN1 encoder

Exclusive interface, compatible with HSF/RSF series encoders (commonly used in Rexroth motors); if a general encoder (Hiperface/1Vpp/TTL) is needed, select ENS instead of EN1.

S2 safety (STO)

Standardly equipped with safety torque shutdown, meets mechanical safety standards, no additional safety module required.

No expansion, no FW

Pure basic configuration, simple functions, stable and reliable; firmware needs to be ordered separately (such as IndraWorks engineering package).

IV. Application Scenarios

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

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

Rexroth HSF/RSF encoder motor control

Automation production lines requiring STO safety function
