Mitsubishi MR-JE-300A 3000W 3kW AC Servo Drive High Precision Industrial

Description

The Mitsubishi MR-JE-300A 3000W AC Servo Drive is an industrial-grade AC motion control amplifier engineered by Mitsubishi Electric. Belonging to the renowned MELSERVO-JE series, this 3.0kW general-purpose drive converts command signals into ultra-precise electrical currents to govern motor speed, positioning, and output torque.

Engineered for machine builders, panel integrators, and industrial maintenance technicians across Bangladesh, the MR-JE-300A provides high dynamic response and operational stability. With its built-in positioning functionality, Advanced One-Touch Auto-Tuning, and real-time vibration suppression filters, this drive allows easy setup while handling heavy workloads in packaging lines, textile machinery, CNC axes, and automated material handling equipment.

Key Features

Installation & Maintenance Guide

Installation Requirements:

• Mount the drive unit vertically inside a clean, well-ventilated metal control cabinet to allow proper convective heat flow.
• Maintain standard clearance margins above, below, and on both sides of the amplifier unit as specified by Mitsubishi guidelines.
• Connect 3-phase 200V AC power lines using recommended circuit breakers and bond the Protective Earth (PE) terminal securely.
• Use shielded twisted-pair cables for pulse input, analog signals, and encoder communication to mitigate electrical noise.

Maintenance Tips:

• Periodically clean drive heat sinks and cabinet intake filters to prevent dust buildup from impairing cooling efficiency.
• Routinely check screw terminal blocks and quick-connect plugs for firm physical contact.
• Verify cabinet exhaust fans operate properly to keep ambient enclosure temperatures below 55 °C.

Safety Instructions:

• Always disconnect main line AC power before conducting wiring, inspection, or terminal maintenance.
• Wait a minimum of 15 minutes post power-off to ensure internal high-voltage storage capacitors have fully discharged before handling terminals.
• Never connect main AC power directly to motor output terminals U, V, and W, as this will permanently damage internal power modules.
