The UM Series Low-Voltage Servo Integrated Drive is a new-generation high-performance, high-reliability servo motor-drive integrated product launched by Beijing Hollysys Motor Technology Co., Ltd. It adopts an innovative full-digital motor control algorithm, enabling precise control of the servo motor's position, speed, and torque. The drive part of this series is based on the 3rd-generation DSP platform, and leverages the powerful performance of TMU, FPU, and FDIV to implement motor control with high-speed floating-point operations.

Supply Voltage		24~60VDC
Control Characteristics	Control Method	SVPWM modulation, closed-loop vector control, CLA current loop acceleration
	Speed Control Accuracy	±1 rpm
	Position Control Accuracy	±1 pulse
	Braking Method	External auxiliary module for enhanced discharge (SC-RSDC-B)
	Overload Capacity	Overload ratio is calculated based on actual maximum current, with an overload duration of 10s; Users must ensure proper heat dissipation and heat conduction to guarantee normal operation of the drive; Please keep the drive heat sink temperature below 85℃; suspend operation if the temperature exceeds this limit.
