I. Model Breakdown

CSB01.1C-SE-ENS-NNN-L2-S-NN-FW

CSB01 series, version 01.1, C = scalable

SE: Main communication = SERCOS optical fiber (II/III)

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

NNN: No second encoder interface

L2: Safety = STO (SIL3 / Cat.4 PLe)

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

NN: No special options

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

II. L2 Safety Functions (Key Points)

L2 = STO (Safe Torque Off), highest level:

EN 62061: SIL3

EN ISO 13849-1: Cat.4 / PLe

Function: Dual-channel hardware cuts off motor torque to prevent accidental startup

Comparison:

L2: STO, SIL3/PLe (highest)

L10S: STO + SS1, PLd/SIL2 (medium)

III. Core Technical Specifications

Control axes: single axis

Power supply: DC24V ±10%, approximately 8W

Control cycle: current 125μs / speed 250μs / position 500μs

Encoder: only CH1 = ENS (fully compatible with motor), no CH2

Communication: optical SERCOS + RS232 + Ethernet service port

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

Safety: L2 (STO SIL3/PLe)

Panel: standard LED + 4 keys

Size / Weight: approximately 241×49.5×103mm / approximately 1.2kg

IV. Application Scenarios

Fiber SERCOS bus: strong interference, long distance, multi-axis synchronization

Single motor encoder: no external encoder required

Highest safety level requirement: machine tools, robots, packaging / printing, automotive equipment (requires SIL3/PLe)

Fast debugging: standard panel + pre-installed firmware, plug-and-play
