380V Robot Universal Servo VFD Variable Frequency Drive

ZF900-E Series Robot specific universal servo variable frequency drive

Robot specific universal servo frequency drive is a drive control device designed for robot systems, which combines high-precision control of servo motors with the speed regulation function of frequency converters. It is suitable for robot application scenarios that require flexible movement, precise positioning, and high dynamic response.

The ZF900E series developed and produced by our company adopts synchronous motor mode, and synchronous motors have core advantages such as constant speed, high power factor, and high efficiency, which are suitable for various industrial occasions that require stable operation, energy saving and consumption reduction.

Core functions and features

• high precision control: Using vector control or direct torque control technology to achieve precise closed-loop control of position, speed, and torque. The position control accuracy can reach ± 1 pulse, and the speed fluctuation rate is less than 0.1%, meeting the high-precision requirements of robot joint motion.
• Wide speed range and high dynamic response: Speed ratio ≥ 1:5000, speed range covering 0-6000 RPM, supporting rapid acceleration and deceleration (such as 0-3000 RPM/s). The response time of the current loop is ≤ 50 μ s, and the response time of the speed loop is ≤ 1ms, ensuring the agility of the robot's movements.
• High power density and compact design: The power density is increased by 30% compared to traditional frequency converters, and the volume is reduced by 40%, which is suitable for the compact space requirements of robot joints.
  Supports IP65 protection level, suitable for complex working conditions of industrial robots.
• Safety and reliability: Built in STO (Safe Torque Off) safety function, compliant with ISO 13849-1 PLd safety standard.
  Mean Time Between Failures (MTBF)>50000 hours, with redundant design for critical components.

The robot specific universal servo frequency converter has become the core component of robot motion control through high-precision control, high dynamic response, and compact design. With the advancement of technology, our company will develop towards integration, intelligence, and standardization, promoting the evolution of the robotics industry towards greater efficiency, safety, and flexibility.
