Product Description
The Mitsubishi MR-J4-350B4-RJ amplifier, designed for high-performance industrial applications, offers precise positioning (0.01 arc-min) via absolute encoder feedback, operates between 0C and 55C, and incorporates safety features like STO and Safe Stop 1. It delivers 3.5 kW output power at 16.0 A, requiring a 200-230 V (10%) 3-phase AC supply and maintaining a 200-230 V output voltage. Featuring forced air cooling, it supports vector and position control, communicates via RS-422/485 and SSCNET III, and can achieve speeds up to 3000 RPM depending on the motor.
Is Your Device Showing These Signs?
The Mitsubishi MR-J4-350B4-RJ servo drive commonly exhibits issues such as overcurrent faults, often stemming from shorted motor windings or incorrect wiring. Parameter corruption within the drive's memory leads to erratic motor behavior and positioning errors, necessitating parameter resets and configuration. Communication failures via the RJ45 connector and associated network protocols are frequent, requiring inspection of cable integrity and network settings. Overheating due to inadequate cooling or excessive load causes thermal trips, addressable through improved ventilation and load reduction. Finally, encoder feedback problems result in velocity fluctuations and positioning inaccuracies, demanding encoder cable checks and encoder replacement if faulty.
