Delta Electronics VFD-EL manual internal, setting frequency, 08.16

Chapter 4 Parameters

These parameters set the Skip Frequencies. It will cause the AC motor drive never to remain within these frequency ranges with continuous frequency output.

These six parameters should be set as follows Pr.08.09 ≥ Pr.08.10 ≥ Pr.08.11 ≥ Pr.08.12 ≥ Pr.08.13 ≥ Pr.08.14.

The frequency ranges may be overlapping.

	command	08.09

08.15 Auto Restart After Fault			Unit: 1
Settings	0 to 10		Factory Setting: 0
	0	Disable

Only after an over-current OC or over-voltage OV fault occurs, the AC motor drive can be reset/restarted automatically up to 10 times.

Setting this parameter to 0 will disable automatic reset/restart operation after any fault has occurred.

When enabled, the AC motor drive will restart with speed search, which starts at the frequency before the fault. To set the waiting time before restart after a fault, please set Pr. 08.07 Base Block Time for Speed Search.

08.16	Auto Reset Time at Restart after Fault		Unit: 0.1
	Settings	0.1 to 6000 sec	Factory Setting: 60.0

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.
