I. Model Breakdown

CSB01.1C-S3-ENS-MA1-NN-S-NN-FW

CSB01.1C: CSB01 series, version 01.1, C = configurable (with expansion slot)

S3: Main communication = SERCOS III (Ethernet hard real-time bus), dual RJ45, 100 Mbps, cycle up to 250 µs

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

MA1: Option 2 = Analog I/O expansion module: 2 analog inputs + 2 analog outputs, ±10V, 12-bit resolution

NN: Safety = No integrated STO safety function

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

NN: Special functions = None

FW: Pre-installed official firmware + authorization, plug-and-play

III. MA1 (Analog I/O) Usage

2AI: Receive external **±10V signal** (such as tension, pressure, speed setpoint)

2AO: Output **±10V signal** (such as speed / torque feedback, tension setting)

Typical scenarios: Tension control, pressure closed-loop, analog spindle synchronization, frequency linkage

IV. S3 (SERCOS III) + MA1 Combination Advantages

High-speed bus + analog closed-loop: Multi-axis synchronization (S3) + process variable analog quantity control (MA1)

Save expansion card: MA1 directly integrated in the control card, no additional analog module required

Fully compatible motor: ENS interface compatible with all IndraDyn MSK/MHD series

V. Application Scenarios

Machine tools + analog auxiliary drive: Machining center spindle (S3) + analog feed / frequency linkage

Tension control equipment: Printing, papermaking, textile, tension sensor AI + tension output AO

Process control servo: Extrusion machines, injection molding machines, pressure / flow closed-loop

SERCOS III bus system: Schaeffler IndraMotion, third-party SERCOS III master station
