I. Model Field Interpretation

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

SE: SERCOS II real-time bus, compatible with outdated SERCOS II network system

EN1: Encoder interface, supports EnDat 2.1 high-precision digital encoder

EN2: Second encoder interface, same specification as EnDat 2.1, supports dual feedback, full closed-loop control

NNN: No additional expansion modules such as analog, digital, or memory card

S1: Basic safety configuration, equipped with conventional safety logic, without STO safety torque shutdown, without SIL certification

S: Standard local operation panel with one row of LEDs and 4 buttons

NN: No additional optional accessories

No FW: Factory does not pre-install firmware, needs to be ordered separately and burned in for use

Size and weight: 241×103×49.5mm, approximately 0.85kg

Compatible power units: HCS02, HCS03, HCS04

III. Configuration description

Dual encoders full closed-loop

EN1 connects the motor's built-in encoder, EN2 connects an external optical encoder or an external encoder to counteract mechanical transmission errors and ensure high-precision positioning and repeat positioning accuracy.

SERCOS II bus

For retrofitting of existing legacy equipment and spare parts replacement, compatible with the original SERCOS II control system, no need to modify the entire line communication architecture.

S1 basic safety

Only basic safety circuits are equipped, not meeting high-level mechanical safety standards, suitable for conventional industrial equipment.

No expansion, no firmware

Hardware is streamlined, focusing on core motion control; corresponding firmware must be separately purchased for the device to operate normally.

IV. Application scenarios

Maintenance and spare parts replacement of old SERCOS II bus precision equipment

CNC machines, precision inspection equipment, using dual encoder full closed-loop process

Conventional automated production lines, with basic safety protection requirements and no STO function needed

The project requires manually flashing the specified version of firmware for the operation of the equipment
