Delta Electronics AC Motor Drive VFD-EL - Manual (Page 124)

Chapter 4 Parameters|
Revision August 2008, 2ELE, V1.02 4-81
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
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.
