I. Model Segmentation (Full Configuration)

CSB01.1C-ET-ENS-EN2-L2-S-NN-FW

CSB01.1C: IndraDrive CSB, Version 01, Design 1, C = Configurable (with expansion slot)

ET: Main Communication = Multi-Ethernet (multiple Ethernet master stations), supports Profinet IO/Ethernet/IP/EtherCAT (optional)

ENS: Encoder 1 = IndraDyn/Hiperface/1Vpp/TTL fully compatible

EN2: Encoder 2 = SSI absolute value encoder interface (second encoder)

L2: Safety = STO (Safe Torque Off), SIL3 / PLd Cat.4, with start interlock

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

NN: Special Function = None

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

II. Key Differences from EN1 Version (EN1 vs EN2)

EN1: Second Encoder = HSF/RSF (incremental, square wave / sine wave)

EN2: Second Encoder = SSI (serial synchronous interface, absolute value)

→ Can directly connect to absolute value encoder for full closed-loop, no need for battery to maintain position

Encoder Interface:

Channel 1 (ENS): 1 Vpp, TTL, Hiperface, IndraDyn dedicated

Channel 2 (EN2): SSI absolute value encoder (like external grating ruler)

Ethernet: 2×RJ45, Profinet IO RT/IRT, Ethernet/IP, TCP/IP

Safety Function: STO SIL3 (EN 62061), PLd Cat.4 (EN 13849-1)

Motor end (ENS) + external absolute value (SSI) full closed-loop, higher positioning accuracy

Suitable for machine tools, gantries, synchronous shafts, tension control

Multiple Ethernet One Network Multiple Protocols:

Directly connect to mainstream PLCs such as Siemens (Profinet), Rockwell (Ethernet/IP)

Highest Safety Level STO SIL3:

Meet safety standards for machine tools, automotive, and new energy equipment

C-type Expandable: With expansion slot, can add communication / encoder / safety module

Firmware Pre-installed FW: Factory authorization, no additional activation required, plug-and-play

V. Typical Combinations (Control Card + Power Unit + Motor)

Control Card: CSB01.1C-ET-ENS-EN2-L2-S-NN-FW

Power Unit: HCS02.1E-W0028-A-07-00 (28A, compatible with 7.5–15 kW motors) Motor: IndraDyn MSK/MHD series (synchronous servo, with Hiperface/1Vpp encoder)

External feedback: SSI absolute optical encoder (such as Heidenhain)

Six. Application scenarios

Machine tools: machining centers, lathes, grinding machines - full closed-loop positioning, dual feedback

Automobile: welding, assembly, stamping safety STO + high precision

Packaging / Printing: high-speed synchronization, tension control with dual encoder feedback
