Delta Electronics VFD-E manual 08.12, 08.13, 08.14, 08.16

			Chapter 4 Parameters
08.12	Skip Frequency 2 Lower Limit		Unit: 0.01
08.13	Skip Frequency 3 Upper Limit		Unit: 0.01
08.14	Skip Frequency 3 Lower Limit		Unit: 0.01
	Settings	0.00 to 600.0Hz	Factory Setting: 0.00

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.

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
