Product Description
The MR-J2S-20CL1 is a lightweight (0.7 kg) AC servo amplifier from the MELSERVO MR-J2 series, designed for precise motion control with a 200W rated output. Operating on a single-phase 100V power supply (85-127 VAC tolerance), it supports motion programming for advanced automation. It functions between 0-55C and can be stored between -20-65C, but its IP00 rating means it lacks dust and moisture protection.
Is Your Device Showing These Signs?
The Mitsubishi MR-J2S-20CL1 servo amplifier commonly experiences issues related to encoder feedback malfunction, resulting in positioning errors and drive instability. Overcurrent faults are frequent, stemming from motor winding shorts or excessive load demands. Communication errors on the SSCNET III network disrupt coordinated motion control. Power supply failures within the drive module lead to complete system shutdown. Parameter corruption necessitates reprogramming to restore proper functionality.
