III. Comparison of PB Series Safety Configuration Table

Model Communication Encoder 2 Security Level Key Differences

CSB01.1C-PB-ENS-NNN-L1-… PROFIBUS No STO SIL2/PLd Basic safety, moderate cost

CSB01.1C-PB-ENS-NNN-L2-… PROFIBUS No STO/SS1 SIL3/PLe Advanced safety, for automotive/robotics

CSB01.1C-PB-ENS-NNN-NN-… PROFIBUS No No safety Economical general-purpose, no safety requirements

Four. Functional Highlights

无缝对接 PROFIBUS + Siemens PLC： Stable and efficient， cycle time 250 μs

Single encoder + STO safety (L1)：

Only ENS feedback at motor end， cost optimization

Integrated STO SIL2/PLd， meets conventional safety standards， no additional safety module required

C-type expandable： With expansion slot， can add safety module (L2)， communication module later

Firmware pre-installed FW： Factory authorized， plug-and-play

Single encoder architecture： Suitable for scenarios without external feedback but requiring safety shutdown

Five. Typical Combinations

Control card： CSB01.1C-PB-ENS-NNN-L1-S-NN-FW

Power unit： HCS01.1E-W0018-A-07-00 (18A， compatible with 3–7.5 kW motors)

Motor： IndraDyn MSK/MHD series (synchronous servo， with Hiperface/1Vpp encoder)

Six. Application Scenarios

Factory automation： Siemens PLC + PROFIBUS， single-axis positioning with safety shutdown required

Machine tools： Ordinary lathes， milling machines， single encoder + basic safety

Packaging / Printing： High-speed synchronization， tension control， safety priority

Material handling： Conveyor lines， sorting equipment， STO emergency shutdown

Renovation of old equipment： Replace old Indramat drives， retain PROFIBUS + add safety
