The Mitsubishi MR-J3-20T is a Cable CC-Link CC-Link Version 1 for industrial control and automation applications.
The Mitsubishi MR-J3-20T is a turret indexer AC servo amplifier from the MELSERVO MR-J3 series. It operates on a supply voltage rating of 200 to 230 Volts AC and provides a rated output voltage of 170 Volts AC for high-performance indexing tasks.
How does the MR-J3-20T address unstable turret positioning?
Turret indexing demands exact stopping and repeatable motion, yet fluctuating supply conditions or inadequate braking can cause position drift. This unit counters this with sine wave pulse width modulation (PWM) control and current control, which together maintain stable torque delivery. A built-in dynamic brake enables quick stops, reducing overshoot during index transitions. Rated current is 1.5 Amperes, and input current consumption matches at 1.5 Amperes, so the amplifier draws consistent current from the supply.
Which electrical parameters ensure precise turret indexing?
The amplifier accepts a 3-phase or 1-phase input, giving installers flexibility across industrial power systems. Rated active power is 200 Watts, while power consumption is 30 Watts, indicating efficient operation during indexing cycles. Natural cooling removes the need for auxiliary fans, which simplifies cabinet design and reduces maintenance points. The enclosure rating is IP00 (open enclosure), so the unit must be mounted inside a protected control panel. Weighing 1.75 lbs (0.79 kg), it adds minimal load to panel mounting structures.
How does CC-Link integration reduce commissioning time?
Communication with This unit uses RS-422 and CC-Link protocols, and the unit is applicable to CC-Link Version 1.10. This allows direct connection to a CC-Link network for command and feedback exchange. Integration Note: wiring into a CC-Link network may require an external gateway or connection module; confirm cable and gateway compatibility with AutoDCSTech before installation. Because the amplifier supports both RS-422 and CC-Link, engineers can select the interface that matches the existing control architecture.
What installation practices support long-term reliability?
Mount the amplifier in a vertical orientation within an enclosure that respects the IP00 rating. Maintain clearance for natural convection, since cooling relies on ambient airflow rather than forced ventilation. Verify that the supply voltage stays within the 200 to 230 Volts AC range and that input current does not exceed 1.5 Amperes. For maintenance, inspect connections and clean airflow paths periodically; the dynamic brake is internal and requires no user adjustment. Following these practices supports consistent turret indexing over time.
