Section 1: Understanding VFD & Start up Parameters
Understanding VFD- Variable Freq. Drive
Selecting the source of VFD
Selecting the source of Operation in VFD
Section 2: Auxiliary Parameters in VFD

This video explains how we can alter the acceleration & deceleration time in the VFD. This is mandatory & time varies as per the application.


Jog Mode is also known as "Inch", In this mode, we can assign Customize Freq. (Jog Freq) to run the motor by Push button. This mode is required many a times in Maintenance operation for adjustment of motor position or to run motor temporarily at slow speed


This video explains How to select second source of frequency. In VFD, you can assign two sources & can toggle between these two source on your favorable condition. Check out this video to know more..


Here, We have shown how to disable reverse operation of the motor by using special parameter.


This video explains "How to Secure the Parameter" from unauthorized access.


This video explain Multiple Frequency options in the VFD. In an application where you want to change the speed by actuation of Sensor, Limit switch or any other condition. We can have 3 or more step speed in VFD

Section 3: Internal PLC Mode Operation in VFD

Do you know, some VFD's has an Internal PLC. Check out its functionality in this video. It explains how you can have 7 Steps of Frequency with respective time frame.

Internal PLC Mode- II & III
Internal PLC Mode- Direction Control
Section 4: Other Special Parameters in VFD

This video is about changing the Acc./Dec. time to another range.


This video explains how to limit the frequency of VFD under certain bounded frequencies


This videos show's how to Reset the External fault using external input.


Delta VFD has internal counter, which can be used to count the events & take action once the count is complete.


This video explains how we can change the external control of VFD (Keypad, 0 ~ 10 VDC, 4 to 20 mA, Comm.)

Section 5: VFD Feedback Signals
