Introduction to West Drive EH640A 

 1. The application of precision engraving machine 

 Industry application requirements: control mode with multi VF curve. 

 Maximum speed of about 24000r/min, equivalent to 400Hz (2-class high-speed motor) 

 West EH600M series of maximum output frequency of 1500Hz, EH600A series of maximum output frequency is 650Hz (non-standard frequency-specific models can output 1500Hz), can satisfy their requirements 

 Because users are equipment for engraving machine manufacturers, so the need to provide copies of the keyboard to quickly set the parameters to achieve. 

 EMC requirements of high jamming equipment to prevent the industrial computer. 

 2. There is tension inspection machine 

 Difference between the two drive through the speed to achieve constant tension cloth 

 EH600 series stacking function of the frequency of a fixed speed difference can be achieved, accurate tension control 

 3. Constant pressure water supply on the application 

 West converter built-in intelligence PID function, sleep wake-up function, PID preset frequency function; 

 Pressure setting can be directly used keyboard UP / DW button to set the pressure setting and feedback can gauge the range to display, easy and intuitive. 

 4. Musical fountain on the application (cooperation project with the Beijing University professor) 

 a, high starting torque 

 b, strong overload 

 c, excellent acceleration and deceleration characteristics 

 d, a standard MODBUS interface, pulse input, analog input interface to set the frequency 

 600W (A) series inverter in the dual-frequency applications on the drawing machine 

 Features: 

 The use of a large number of cases have proved EH600W (A) series inverter to achieve drawing machine tension control, not only can save PID board, in stability, ease of debugging also have greatly improved 

 EH600W (A) in the drawing machine industry, the core requirements: 

 A: speed (2500 meters has been achieved / min) 

 B: diameter (minimum 0.040mm) are among the best in the domestic inverter. 

 600W (B) series inverter in power retractable Line 

 Industry Requirements: 

 speed in taking a lead, put the lead taken along line speed speed speed speed; 

 b In the lead to take the speed reducer, the release also followed the lead taken speed slowed down; 

 c When the stable operation at a speed, off frame to stabilize the pendulum rod; 

 d When the thread and break when required to automatically reverse reel; 

 e taken in the quoted rate is 0, the pay-off the motor to enter the shutdown state, does not appear repeatedly swing; 

 I EH600W (B) to achieve all of these features, and can be restored by FD.10 = 5 to the power retractable cable factory default values, the user can be used as long as the correct wiring. 

 7. Xilin drive straight into the wire-drawing machine in the application 

 System solutions: Each pass can be used between the feed-forward PID control, the main rate of flow from the former level metal seconds calculated, PID tuning speed as the system volume, speed, the internal implementation of the inverter operation, fast response, low cost, Debugging
