• Continuous Output Current (AC-3): 31.0 A
• Supply Voltage: 380–480 V AC, 3-phase, 50/60 Hz
• Frame Size: R4 (the typical next frame up from R3 for higher current series)
• Enclosure Rating: IP20 (standard)

Safety & Built-In Features

• Safe Torque Off (STO) for safe operation (SIL 3 level)
• Built-in C3 EMC Filter, ensuring compliance with EMI standards
• Integrated Brake Chopper to handle dynamic braking needs
• Configuration Tools:
• FlashDrop — setup drive without live power
• DriveWindow Light — PC software for setup, tuning, and diagnostics
• Embedded Logic Functionality: Includes macros, sequence programming, and panel-specific assistant tools

Mechanical & Environmental Specifications

• Approximate Dimensions (W × H × D):
• Width: ~169 mm
• Height: ~300–350 mm (higher than R3, reflecting R4 frame design)
• Depth: ~195 mm
• Estimated Weight: ~4.5 kg
• Operating Ambient Temperature: –10 °C to +40 °C (with possible derating above that range)
• Ventilation Requirements: 75 mm clearance top and bottom; 0 mm clearance between units for side-by-side mounting
• Estimated Thermal Loss: ~400–450 W at full load
