III. Comparison with Key Models of the Same Series (PB) Table

Model Communication Encoder 2 Safety Core Function

CSB01.1C-PB-ENS-EN2-NN-…-FW PROFIBUS SSI Absolute Value (5V) No Full Closed Loop + Absolute Value, Machine / High-end Positioning

CSB01.1C-PB-ENS-EN1-NN-…-FW PROFIBUS HSF/RSF Incremental (8V) No Dual Incremental, Synchronous / Tension Control

CSB01.1C-PB-ENS-NNN-NN-…-FW PROFIBUS No No Single Encoder, Economical General

Four, Key Features

Native PROFIBUS compatibility with Siemens: Connects to S7-300/400/1200/1500, stable and efficient, with the shortest cycle of 250 μs

Motor Incremental + External SSI Absolute Value Dual Feedback:

Motor end (ENS) closed loop + External SSI Absolute Value full closed loop

Power-on does not require zeroing, higher positioning accuracy, suitable for machining centers, high-precision platforms

C-type expandable: With expansion slots, can be later installed with safety modules (L1/L2), communication modules

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

No safety cost optimization: NN eliminates safety circuit cost, suitable for scenarios without safety requirements

Five, Typical Combinations (Control Card + Power Unit + Motor)

Control Card: CSB01.1C-PB-ENS-EN2-NN-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 Value Encoder (such as machine grating scale, rotary absolute value encoder)

Six, Application Scenarios

High-end Machine Tools: Machining Centers, Grinding Machines, Full Closed Loop + Absolute Value Positioning

Automation Equipment: High-precision Positioning Platforms, Gantry Frames, Power-on without zeroing

Renovation of Old Equipment: Replace old Indramat drives, retain PROFIBUS + Absolute Value architecture

Packaging / Printing: High-precision Synchronization, Tension Control + Absolute Value Position Memory
