Product Overview

W505 is a sensorless vector control controller for AC motor drive applications. It provides stable frequency output, flexible control sources and complete motor protection for industrial equipment.

The series is suitable for customers who need a compact controller with SVC, V/F and torque control, built-in PID and configurable I/O.

Key Selling Points

Supports SVC, V/F and torque control.
Output frequency range: 0Hz to 600Hz.
Built-in PID control and up to 16-step simple PLC speed control.
Non-stop function during instantaneous power cut and speed trace start for rotating motors.
Automatic voltage regulation keeps output voltage stable under input fluctuation.
Protection functions include over-current, over-voltage, under-voltage, overheat, phase failure and overload.

FAQs

What is the W505 used for? ▶

W505 adjusts motor speed to suit the work being done. It can be used with suitable motor-driven equipment, including pumps, where changing speed is useful.

How should I select a W505 controller? ▶

Choose a model using the motor nameplate and the power supply available on site. The controller and motor ratings must match; have the chosen combination checked before installation.

Can W505 work with an existing pump motor? ▶

W505 is intended for ordinary three-phase motors. Whether an existing pump is suitable depends on its motor data, power supply, pump load, and the selected W505 model.

Is W505 available for different supply arrangements? ▶

The series includes 220 V and 380 V versions. Only specified lower-power 220 V models are listed with single-phase input, so do not assume that any model or motor will suit a domestic supply.

Can W505 use preset operating speeds? ▶

Yes. You can save different running speeds and switch between them as needed. This is useful when the same equipment does different jobs.

Where do I start or adjust a W505? ▶

The controller has a local keypad for normal setup and use. External controls can also be set up for an installation; have electrical connections and settings completed by a trained installer.

Will running slowly affect the motor? ▶

It can. A standard motor may receive less cooling at low speed, so the intended speed range and cooling conditions should be checked when selecting the system.

What should I do when W505 reports a fault? ▶

Do not repeatedly reset the controller without finding the cause. Use the fault information to check the power supply, motor, pump load, and wiring, then seek service help when needed.
