I. Model Breakdown

CSB01.1C-SE-ENS-EN1-NN-S-NN-FW

CSB01.1C: CSB01 series, version 01.1, C = scalable

SE: Main communication = SERCOS (fiber optic interface, II/III compatible), non-electrical port S3

ENS: Encoder 1 (motor end) = 12V, fully compatible with Hiperface/1Vpp/TTL/IndraDyn

EN1: Encoder 2 (external / load end) = HSF/RSF encoder interface (1Vpp/TTL), second encoder closed-loop

NN: No safety function (not L1/L2)

S: Panel = standard single-line LED + 4 keys

NN: No special function

FW: Pre-installed firmware, plug-and-play

II. Key Differences (SE vs S3; EN1 vs NNN)

1) Communication: SE (fiber optic SERCOS) vs S3 (electrical SERCOS III)

SE: Fiber optic interface, strong anti-interference, long distance, compatible with old SERCOS II/III

S3: Dual RJ45 electrical ports, SERCOS III, simple wiring, low cost

2) Encoder: EN1 (dual encoders) vs NNN (single encoder)

EN1: Dual closed-loop (motor encoder + external encoder), used for high-precision positioning / synchronization (such as machine spindle, sheet tension)

NNN: Only motor single encoder, basic speed / position control

III. Core Technical Specifications

Control axes: Single axis

Power supply: DC24V ±10%, power consumption approximately 8W

Control cycle: Current 125μs / Speed 250μs / Position 500μs

Encoder:

CH1: ENS (motor, fully compatible)

CH2: EN1 (external, HSF/RSF)

Communication: Fiber optic SERCOS + RS232 + Ethernet service port

I/O: 5DI / 3DI/O / 1 relay output

Safety: None (NN)

Panel: Single-line LED + 4 keys

Size / Weight: 350×80×220mm / approximately 1.2kg
