• Standard S7‑400 plug‑in signal‑module dimension
• Front‑panel LED indicators for axis status and fault alarm
• Front‑mount terminal block for encoder, limit‑switch and drive‑command wiring
• Rear edge connector connects S7‑400 rack back‑plane bus Working Principle: Motion‑task parameters downloaded from S7‑400 CPU store in module local memory. On‑board processor calculate motion profile and generate drive setpoint signal. Actual axis position read from incremental encoder input. Local hardware execute closed‑loop position regulation. Limit‑switch signal realize hardware over‑travel protection. Status and fault information exchange with main CPU over back‑plane bus. Installation Requirements:
• Insert into any free slot of S7‑400 UR‑series rack
• Use shielded twisted‑pair cable for encoder feedback wiring
• Separate power cable and signal cable to satisfy EMC requirement
• Tighten front‑panel terminal‑block screws to specified torque
• Control cabinet ambient temperature keep within 0 °C‑60 °C Usage Precautions:
• Complete axis mechanical‑parameter configuration in STEP 7 before commissioning
• Verify encoder phase‑sequence wiring before enable axis motion
• Hardware limit‑switch must be wired for anti‑over‑travel safety protection
• Do not exceed maximum encoder input frequency rating
• Execute ESD protection procedure when handle module out of rack
