- The latest version of PC online software, real-time monitoring of drive status and parameter setting
- Injection molding machine
- Die casting machine
- Hydraulic machinery
Technical Specifications
- after the servo driver obtains the pressure and flow commands from the injection molding machine controller, it performs PID Calculus with the actual pressure and rotation speed feedback to calculate the most suitable control amount to drive the servo motor and oil pump, so the control system has fast response and high repetition accuracy.
- Voltage: 220V / 460V
- Power range (kW):11~37 (230V)/11~75 (460V)
- Carrier frequency (Hz): adjustable
- Operating voltage range: plus or minus 10%(VJ-C -15 ~ 10%)
- power frequency variation range: plus or minus 5%
- Cooling method: air cooling/oil cooling (VJ-C oil cooling power range: 460V 30 ~ 75kW)
- pressure feedback input: voltage type DC 0~10V and current type 4 ~ 20mA
- Communication protocol support: Modbus and CANopen
Plain language sourcing guide for Delta VFD-VJ series frequency inverters
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
