I. Model Breakdown

CSB01.1C-ET-ENS-NNN-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 = Fully compatible with IndraDyn/Hiperface/1Vpp/TTL

NNN: Encoder 2 = None (No second encoder interface)

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/EN2 Versions

NNN: Only single encoder (ENS), no second encoder interface → Lower cost, simpler wiring

EN1: Dual Encoder (ENS + HSF/RSF Incremental)

EN2: Dual Encoder (ENS + SSI Absolute)

III. Core Technical Specifications (Control Unit)

Control Voltage: DC 24 V ±10%, Power Consumption: Approximately 8 W

Control Axes: Single Axis (1 Servo Closed Loop)

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

Encoder Interface: Only Channel 1 (ENS): 1 Vpp, TTL, Hiperface, IndraDyn Specific

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

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

I/O: 5DI / 3DI/O / 1 Relay Output

Panel: Single-line LED + 4 Keys (Local Debugging, Address, Parameters)

Size (mm): 350 × 80 × 220 (Standard Card Specification)

Weight: Approximately 1.2 kg

Protection: IP20 (Inside the Control Cabinet)

IV. Functional Highlights (Compared to Ordinary CSB)

Multi-Ethernet One Network for Multiple Protocols: Direct connection to mainstream PLCs such as Siemens (Profinet), Rockwell (Ethernet/IP)

Highest Safety Level STO SIL3: Meeting safety standards for machine tools, automotive, and new energy equipment

C-Type Expandable: With expansion slot, can be later added with a second encoder / communication / safety module

Firmware Pre-installed FW: Factory Authorization, No Additional Activation Required, Plug-and-Play

Economical Configuration for Single Encoder: NNN eliminates the cost of the second encoder, suitable for ordinary single-loop positioning

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

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

Power Unit: HCS02.1E-W0028-A-07-00 (28A, Suitable for 7.5–15 kW Motors)

Motor: IndraDyn MSK/MHD Series (Synchronous Servo, with Hiperface/1Vpp Encoder)

VI. Application Scenarios

General Automation: Single-axis positioning, conveyor lines, simple robotic arms

Machine Tools: Ordinary Lathes, Milling Machines, Machining Centers (Single Loop) Packaging / Printing: Single-axis synchronization, feed control

Automobile: Assembly line, conveying equipment (requires STO safety)

New Energy: Lithium battery / Photovoltaic equipment (basic movement + safety)
