The MDS-B-SPJ2-75 model from Mitsubishi serves as a versatile AC spindle drive system, optimized for performance with the corresponding SJ-PF7.5-01 spindle motor. This system operates on a 3-phase input power supply, accepting voltages from 200 to 230 VAC with input power frequency options of 50 or 60 Hz. It is capable of tolerating voltage fluctuations within a range of 170V to 253V, alongside frequency variations of ± 5%.
This drive is equipped with a regenerative braking system that leverages electrical resistance, enhancing its efficiency in various applications. The control method employs sinusoidal PWM along with vector control technology, ensuring precise operational capabilities. The motor can reach speeds between 35 rpm and 10,000 rpm, which allows for a broad scope of applications.
In terms of mechanical capability, the MDS-B-SPJ2-75 can manage load inertia up to ten times that of the motor itself, indicating its robust design and suitability for demanding tasks. It utilizes HDLC high-speed serial communication as its controller interface, ensuring quick and efficient data transfer between devices.
This spindle drive system is designed to operate effectively within a temperature spectrum of 0°C to 55°C. For storage, it supports a broader temperature range from -20°C to 65°C. Withstanding humidity levels up to 90% relative humidity without condensation, this system is well-calibrated for various environmental conditions. Additionally, it features a vibration tolerance of 5.9 m/s² (0.6G) maximum, making it resilient in dynamic operational settings.
