B&R 8LSA75.E1022D200-0

Product Introduction:

The B&R 8LSA75.E1022D200-0 is a high-power servo drive from the ACOPOS 8L series, designed for demanding multi-axis and high-torque applications. With a rated current of 75A and peak current of 225A, it supports servo motors up to 45 kW. The model features integrated safe motion functions, multi-turn absolute encoder support, and full protocol compatibility for integration into complex automation systems.

Technical Specifications:

Functional Features:

• Safe Motion Functions: SS1 (Safe Stop 1), SLS (Safely Limited Speed), SLP (Safely Limited Position), SBC (Safe Brake Control)
• Electronic camming with up to 64 cam profiles
• Cross-coupling control for gantry and synchronized multi-axis systems
• Load-adaptive feedforward — compensates for varying mechanical loads in real-time
• Energy management — regenerative braking with grid feedback capability (optional AFE module)
• Dual-core processor — separates motion control from communication tasks

Performance Parameters:

Structural Features:

• Large chassis design — accommodates high-power IGBT modules and braking chopper
• Integrated AFE (Active Front End) compatibility — for regenerative energy feedback to grid
• Dual redundant EtherCAT ports — for hot-standby network configuration
• Pluggable power terminals: L1/L2/L3 (3-phase DC), PE, U/V/W (motor)
• Service port (USB/Ethernet) — for parameter backup and firmware update without opening the cabinet

Working Principle:

The 8LSA75.E1022D200-0 uses a dual-core DSP architecture: one core handles real-time motion control (FOC at 3.5 kHz), the other manages communication and diagnostics. The drive receives setpoints via EtherCAT with distributed clock synchronization (jitter < 100 ns). The multi-turn absolute encoder (EnDat 2.2) provides 17-bit single-turn / 16-bit multi-turn resolution, enabling absolute position tracking across power cycles. The safe motion functions are implemented in hardware (SIL 3), ensuring that safety-related stop commands are executed independently of the main processor within < 20 ms.

Key Advantages:

• 75A continuous / 225A peak — handles the highest dynamic loads in the ACOPOS 8L family
• SIL 3 / PL e safe motion — eliminates need for external safety controllers
• Cross-coupling control — perfect for gantry and multi-axis synchronization
• AFE-ready — recovers braking energy, reducing operating costs by up to 30%
• Dual-core architecture — ensures deterministic motion control even under heavy network traffic

Installation Requirements:

• Mounting: Vertical cabinet mounting — minimum 200mm clearance on all sides
• Power Connection: 3-phase 360–750 V DC — cable cross-section min. 25 mm² Cu, max length 5m
• Motor Cable: Shielded servo cable, max 50m (use B&R active extender for > 30m)
• Grounding: PE resistance < 0.05 ohm, use dedicated grounding bus bar
• Cooling: Forced air cooling mandatory — min. 3 m/s airflow, filter cleaned every 3 months
• Braking Resistor / AFE: Required for deceleration energy > 1,000J per cycle

Usage Precautions:

• AFE module installation requires licensed electrician — incorrect wiring causes permanent damage
• Multi-turn encoder battery life: 5 years — schedule replacement during planned maintenance
• Do not operate with cooling fan failure — thermal shutdown occurs at 85°C IGBT junction temperature
• EtherCAT DC (Distributed Clock) must be enabled for cycle times < 1 ms
• Safe motion test must be performed every 6 months per IEC 61508 / ISO 13849
