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
