Product Description

Model Number Interpretation

• 3RA: HR2000/BLA‑08 high‑performance servo controller platform

• 2: 208/230 VAC three‑phase input

• 02: 2 HP rated power

Technical Specifications

• Input: 3‑phase 208/230 VAC ±10%, 50/60 Hz

• Rated Power: 2 HP (1.5 kW)

• Output: For brushless AC servo motors; base speed 3000 RPM

• Control: Single‑board hybrid regulator; precise speed control down to zero speed

• Protection: Line‑to‑line and line‑to‑ground short‑circuit protection

• Feedback: Resolver‑based (compatible with HR2000 motors)

• Enclosure: Chassis (open frame)

• Cooling: Forced‑air

• Weight: ~15 lbs (6.8 kg)

• Ambient: 0–40°C, clean/dry environment

Interface & Communication

• Power Terminals: L1/L2/L3 (input), U/V/W (motor output)

• Control I/O: 24 VDC aux power, start/stop, forward/reverse, analog speed reference (±10 VDC / 4–20 mA), fault relay output

• Communication: No built‑in serial; uses resolver for motor feedback

Core Functions

• High‑Precision Motion: Zero‑speed stable control; fast dynamic response

• Compact Design: Single‑board construction for space‑saving integration

• Remote Monitoring: Fault contact for system‑level diagnostics

• Motor Compatibility: Matches HR2000 series NEMA brushless servo motors

Applications

• Precision automation: CNC machines, pick‑and‑place, assembly stations

• High‑speed positioning: Robotics, packaging, material handling

• Legacy Reliance HR2000 system replacements

Usage & Maintenance

• Mount in a ventilated cabinet with 100 mm clearance for airflow

• Separate power/control cables to avoid EMI; torque terminals to spec

• Before power‑on: Verify input voltage, motor wiring, and resolver connections

• Quarterly: Clean fan/heat sink; inspect terminals and fault contacts

• Safety: Disconnect all power; wait 5 minutes for capacitor discharge before service
