The Mitsubishi MR-J3-100T4 is classified as an AC motion servo drive, commanding performance tailored for industrial applications. This unit has a rated power output of 1000W, equivalent to 1kW, facilitated by a rated current of 2.8A. The drive requires a supply voltage within the scope of 380Vac to 480Vac, categorizing it under the 400V class.
Designed for 3-phase input configuration, the MR-J3-100T4 integrates sophisticated communication capabilities, utilizing CC-Link and RS-422 protocols for efficient data transfer. This enhances its adaptability in automated control systems. A built-in dynamic brake adds to its functionality, along with a regenerative resistor that contributes to energy efficiency by recovering energy during deceleration.
Operating effectively in ambient temperatures between 0°C and +55°C, this servo drive benefits from natural cooling for efficient thermal management. To protect system integrity, it features a suite of safety measures, including automatic shut-offs for overcurrent conditions, regeneration overvoltage, and electronic thermal overloads, guaranteeing stability and reliability in demanding operational conditions. The control mechanisms utilize both sine wave PWM control and current control methods to deliver precise motion control essential for complex automation tasks.
