Delta Electronics VFD-E manual AVR function disabled for stop

Chapter 4 Parameters

This parameter should be used in conjunction with Pr.08.15.

For example: If Pr.08.15 is set to 10 and Pr.08.16 is set to 600s (10 min), and if there is no fault for over 600 seconds from the restart for the previous fault, the auto reset times for restart after fault will be reset to 10.

70%

During auto-energy saving operation is the output voltage lowered as much as possible to keep the load. The output voltage is maximally lowered to 70% of the normal output voltage

08.18Automatic Voltage Regulation (AVR)

Factory Setting: 0

Settings	0	AVR function enabled
	1	AVR function disabled
	2	AVR function disabled for deceleration
	3	AVR function disabled for stop

The rated voltage of the motor is usually 230V/200VAC 50Hz/60Hz and the input voltage of the AC motor drive may vary between 180V to 264 VAC 50Hz/60Hz. Therefore, when the AC motor drive is used without AVR function, the output voltage will be the same as the input voltage. When the motor runs at voltages exceeding the rated voltage with 12% - 20%, its lifetime will be shorter and it can be damaged due to higher temperature, failing insulation and unstable torque output.
