I. Component-by-component disassembly of the model (Key points: SE, EN1+EN2, MEM)

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

SE: SERCOS II master station communication (old model SERCOS, compare S3 = SERCOS III).

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

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

MEM: Multimedia memory card module (MMC), used for firmware storage, parameter backup, and data recording.

S1: Basic safety function (no STO), not SIL3, no safety torque shutdown.

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

NN: No other additional options.

FW: Factory pre-installed complete firmware, ready to use upon power-on.

II. Core parameters (Dual Encoder + MEM version)

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.

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

Communication: SERCOS II, RS232, service Ethernet.

Safety: S1 = basic safety (no STO, not SIL3).

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

Adapter power unit: HCS02/HCS03/HCS04.

Key features

Dual EnDat encoders (EN1+EN2): Support dual feedback of motor encoder + external position encoder, higher positioning accuracy, suitable for closed-loop control scenarios.

MEM storage card: Can store firmware, parameters, and running data, supports quick backup/restore, facilitating equipment maintenance and troubleshooting.

SERCOS II communication: Old high-speed bus, suitable for legacy device compatibility (compare S3 = SERCOS III, does not support µs-level multi-axis synchronization).

III. Configuration highlights (Dual Encoder + MEM value)

EN1+EN2 = Dual encoder feedback

Access both the built-in motor encoder + external optical encoder / encoder for full closed-loop control, with positioning accuracy up to ±1 pulse, suitable for high-precision machine tools, precision positioning tables.

MEM = Local data storage

Can independently store parameters and data without an upper computer, supports one-click backup/restore, quickly restores configuration when replacing the control card, reducing maintenance costs.

SE = SERCOS II (compatible with old system)

Used for upgrading or replacing existing SERCOS II devices, compatible with old Schaeffler drives and controllers, no need to modify the bus architecture.

S1 = Basic safety (no STO)

Suitable for ordinary equipment without high safety requirements, costs lower than S2 (STO/SIL3) version.

IV. Application scenarios

High-precision single-axis positioning: such as precision machine tools, semiconductor equipment, electronic manufacturing equipment (dual encoder full closed-loop).

Requires data retention/backup: local storage of equipment parameters and running data, facilitating maintenance and traceability.

Upgrade replacement of legacy systems: compatible with SERCOS II bus legacy systems, no need to modify communication architecture.

Standard motor + external feedback: motor encoder + external optical encoder, achieve high-precision closed-loop control.
