I. Model Breakdown (Corrected Writing: CSB01.1C, not 01-1C)

CSB01.1C: CSB01 Series V01.1; C = Configurable Type, with Expansion Slot (Different from N-Type Fixed and Non-Extensible)

PB: PROFIBUS-DP Field Bus (X60 Interface, Maximum 12Mbps)

ENS: Main Encoder Port (12V/500mA), Compatible with Hiperface, 1Vpp, TTL, IndraDyn Encoder

NNN: No Second Encoder, Analog Input, Encoder Simulation Expansion

L1: STO Safety Torque Off, SIL2/PLd (Basic Safety Level)

S: Single-line LED + 4-Key Standard Local Panel

NN: No Additional Special Functions

FW: Factory Pre-installed Firmware, Ready to Use upon Power On

II. Core Parameters (C-Type + PB + L1 Common)

Number of Control Axes: Single Axis

Control Power Supply: DC24V ±10%, Approximately 8W

Control Cycle: Current Loop 125μs, Speed Loop 250μs, Position Loop 500μs

I/O: 5DI / 3DI/O / 1 Relay Output (24V/1A)

Communication: PROFIBUS-DP, RS232 (Debugging), Ethernet (Service)

Safety: STO SIL2/PLd (X41 Terminal)

Protection: IP20 (Inside the Cabinet); Dimensions: 103×241×103mm; Weight ≈ 0.8kg

Compatible Power Units: HCS01/HCS02/HCS03

Compatible Motors: MSK, MHD, MKE, etc. IndraDyn Series

III. Key Differences between C-Type (Extensible) and N-Type (Fixed) Table

Model Expansion Slot Communication / Security Expansion Applicable Scenarios

CSB01.1C ✅ Yes Encoders / Communication / Security modules can be added Requires later expansion, multi-protocol compatibility

CSB01.1N ❌ No Fixed configuration, no expansion Standardized, low cost, no expansion required

IV. Comparison with PB (PROFIBUS) series safety models

CSB01.1C-PB-ENS-NNN-NN-S-NN-FW: PROFIBUS, no safety, economy model

CSB01.1C-PB-ENS-NNN-L1-S-NN-FW (this model): PROFIBUS, STO SIL2/PLd, basic safety model

CSB01.1C-PB-ENS-NNN-L2-S-NN-FW: PROFIBUS, STO SIL3/PLe, highest safety model

V. Functions and Applications

PROFIBUS-DP bus: Compatible with mainstream architecture of Siemens PLC, suitable for factory automation, assembly lines, machine tools, etc. with PROFIBUS as the main protocol.

SIL2/PLd basic safety: STO safety stop, meets general mechanical safety requirements, suitable for packaging, printing, ordinary automation equipment.

C-type expandable: Later can add a second encoder, analog quantity, EtherCAT, etc. modules, flexible, suitable for project renovation or multi-scenario adaptation.

Typical scenarios: PROFIBUS + basic safety + single-axis servo system that needs expansion, such as automotive welding lines, machine tools, packaging machinery, automated production lines.
