The UM Series Low-Voltage Servo Integrated Drive is a new-generation high-performance, high-reliability low-voltage servo motor drive unit developed by HollySys Motor Company, Beijing. It adopts advanced full-digital motor control algorithms to achieve precise control of servo motor position, speed, and torque. This series of drives is based on the third-generation DSP platform, leveraging the powerful performance of TMU, FPU, and FDIV to realize motor control with fast floating-point computing capabilities.

Power Supply Voltage		24~60VDC
Control Characteristics	Control Method	SVPWM modulation, closed-loop vector control, CLA current loop acceleration
	Speed Control Accuracy	± 1rpm
	Position Control Accuracy	±1 pulse
	Braking Method	External auxiliary module enhanced discharge (SC-RSDC-B)
	Overload Capacity	Overload multiple calculated based on actual maximum current, with 10s continuous overload duration; Ensure proper heat dissipation and thermal management to guarantee normal operation; Monitor drive heatsink temperature below 85°C; suspend operation if this temperature is exceeded.
