VFD For Pump Control

The VFD For Pump Control is an electronic device that can control the operating frequency of motors and other equipment. It usually works through AC-DC-AC conversion circuits and changes the power supply frequency according to a specific formula to control the motor speed.

It has speed regulation, energy saving, soft start and multiple protection functions. It can smoothly adjust the motor speed, adjust the power as needed, reduce the start-up impact and ensure the safety of the equipment.

It has a wide range of applications, covering industrial equipment, HVAC, transportation vehicles, household appliances and other fields, which can improve efficiency, save energy and improve performance.The PDM30 model VFD For Pump Control is more suitable for installation on a horizontal multistage centrifugal pump to form a horizontal variable frequency pump.

• Operation and display mode

1. Status display mode:

When power on the SPD, it enters the status display mode. When it stops, it displays pressure setting. Press "+" or "-"to modify pressure setting. When it is running,it displays current pressure, operating frequency, and setting pressure. Press the "+" or "-" to switch the display; press "MENU" for two seconds to enter the parameter setting mode.

• Parameter setting mode:

To view or set the parameters, as starting from status display mode, press the "MENU" for 2 seconds to enter the parameter setting mode, and then press the "RUN / STOP" starts to set parameters. After you set the parameter press twice "MENU" to exit parameter setting mode, and return to the status display mode.

• The alarm display mode:

Automatically enter this mode when a drive fault or warning arises; press the "RUN / STOP" to reset, or it can automatically restored the previous mode after the alarm is eliminated.

• Menu Operation

Three-class menus are:

1. Function group (first class)
2. Function code setting(second class)
3. Function code setting(third class)

Instruction of vfd for pump control: In the third class menu, pressing "MENU" or "RUN/STOP" can return to the second class menu. The difference is that pressing "RUN/STOP" first saves parameters to control board, and then returns to the second class menu and shifts to next function code automatically; pressing "MENU" returns to the second class menu directly without saving parameters and keeps staying at current function code.

Under the third class menu, only flicker bit can be modified. Revisable bit will shift automatically after 5 seconds.

Note: For parameters marked with "●", please modify them in stopped state. Parameters marked with "◎" are actual detected and recorded values which can't be modified.
