Mitsubishi developed the MDS-DH-SP-80, an advanced spindle drive unit designed to operate under various industrial conditions. At 4.5 kg, this unit is built with user efficiency in mind. The drive reaches a peak current capacity of 80 A, while its regular output current stands at 19 A, allowing for substantial operational power.

Control of this spindle drive is available through a voltage range of 380 to 440 AC at 50 Hz or 380 to 480 AC at 60 Hz. The adjustable output voltage rests at 340 AC.

This device employs the sine wave PWM regulation method during operation, which maximizes efficiency and minimizes electrical noise. A regenerative braking system is integrated for efficient energy recovery and control. Additionally, the device utilizes forced air for cooling, which helps manage heat generation and maintain performance.

Surge conditions are accommodated with a surge current rating of 18 A and a surge conduction duration of 12 ms to protect against transient voltage spikes. The maximum control current is noted at 0.1 A, and the leakage current to ground reflects a safe rating of 6 mA, allowing for quick grounding with a maximum allowable limit of 15 mA.

Under typical rated operation, the thermal dissipation measures at 291 W, ensuring it stays within operational thresholds during its usage in demanding scenarios.
