MDS-B-SPJ2-075

The Mitsubishi MDS-B-SPJ2-075 unit is an AC spindle drive designed specifically for use with the SJ-P0.75A spindle motor. Weighing only 1.0 kg, it is compact and integrates easily into numerous systems. The dimensions measure 168 mm in height, 70 mm in width, and 135 mm in depth. This drive utilizes sinusoidal PWM control in combination with current control using vector techniques, ensuring smooth and efficient operation. For braking, it features a regenerative method combined with electrical-discharge resistance.

This spindle drive functions within a 3-phase power supply voltage range of 200V to 230VAC and is capable of operating at both 50Hz and 60Hz. Under voltage variations, it can handle a range of 170V to 253V and maintains a frequency variation within ± 5%. The power facility rating is set to 2.

Speed control is effective across a broad spectrum, allowing speed adjustments from 35 to 10,000 RPM to meet diverse application requirements. It can also manage significant load inertia, catering to loads of up to 10 times the motor's moment of inertia.

For connection, the unit employs an HDLC high-speed serial bus interface. In operation, it functions effectively in ambient temperatures ranging from 0°C to 55°C while being stored under conditions of -20°C to 65°C. The humidity tolerance is good, with operational capabilities up to 90% relative humidity, and there should be no condensation present.
