Description

Hardware and Performance Specifications Auxiliary supply: 24 V DC, 18‑30 V DC wide‑range input Power consumption: ≤13 W Feedback interface: Incremental encoder differential signal input; support HTL/TTL encoder signal Control function: Position loop closed‑loop calculation, position‑following, positioning, jog control Mounting mode: Plug‑in expansion board for DCS500/DCS800 DC drive cabinet Protection class: IP20 Operating temperature: ‑25 ℃ ~ +70 ℃ Storage temperature: ‑40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial electromagnetic‑compatibility standards Dimension & weight: approx. 365 × 190 × 40 mm, weight approx. 0.75 kg Certifications: CE approval

Main Functions Collect incremental encoder pulse feedback signal to obtain real‑time motor position and speed value. Execute high‑precision position‑loop algorithm, output speed set‑point to DC drive main controller. Support multiple working modes: fixed‑position positioning, position following, jog operation, angle‑position control. Realize position‑limit protection, over‑speed monitoring and position‑deviation fault judgment. Front‑panel LED indicators display power‑on status, encoder signal status and hardware‑fault alarm codes for on‑site inspection. Hardware self‑diagnosis detects encoder signal loss, signal abnormality and internal circuit faults, upload fault‑alarm information to DC drive main unit. Parameter configuration, position‑loop gain setting and fault diagnosis are completed by ABB DriveWindow engineering software.

Installation Requirement Plug‑in installation inside DCS500 / DCS800 DC drive cabinet. Strictly separate power cables and encoder differential signal wiring, encoder cable adopt shielded twisted‑pair cable. Ensure reliable cabinet protective grounding. After board replacement, confirm full part‑number DAPC100 / 3ASC25H209 matches original project configuration, download complete drive parameter file. Perform encoder wiring check, position‑loop parameter tuning and positioning‑action test. Different hardware revisions cannot be directly interchanged without parameter adaptation. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Position‑control‑board spare‑part for ABB DCS500/DCS800 DC drive systems; widely used for metallurgy, papermaking, printing and winding‑equipment DC‑motor precise‑position control system maintenance and spare‑part replacement.

Key Features

1. Dedicated position‑control expansion board for ABB DC drives, independent position‑loop calculation, reduce main‑controller computing load.
2. Support differential encoder input, strong anti‑interference performance for harsh industrial‑site environment.
3. Multiple position‑control modes, adapt to various process‑position‑control requirements.
4. Complete self‑diagnosis function for encoder and position‑deviation fault, convenient for on‑site fault‑location.
5. Strict full‑part‑number matching shall be observed during spare‑part replacement; cannot be substituted by other DAPC‑series boards without parameter re‑tuning.
