Defines the number of automatic fault resets at '31.11' (Automatic reset item 2)

31.15 Earth Fault

0: Disabled

Range: 0.0 ~ 100.0 % in 0.1 %

Initial value: 0.0 %
Program to enable the Ground fault detection and its fault level as a percentage of rated
current

31.16 Supply phase loss

0: Disabled

Range: 0 ~ 30 Sec in 1 Sec

Initial value: 10 Sec
Enables & sets the time period to determine if an Input Phase Loss occurs. The VFD
monitors the ripple on the DC bus voltage and if it occurs for the programmed magnitude
and time period an Input Phase Loss fault will occur. The ripple on the DC bus will cause
heating to the DC Bus capacitors which will shorten their life.

31.17 Stall function

0: No Operation

1: VFD overload

2: Over voltage

3: VFD overload and Over voltage ----- Initial value
Select a overload or overvoltage restriction modes

Set 0: No Operation
Overload Restriction Mode=Off, Overvoltage Restriction Mode=Off

Set 1: VFD overload
Overload Restriction Mode=On, Overvoltage Restriction Mode=Off

Set 2: Over voltage
Overload Restriction Mode=Off, Overvoltage Restriction Mode=On

Set 3: VFD overload and Over voltage
Overload Restriction Mode=On, Overvoltage Restriction Mode=On

31.18 Stall current limit

Range: 20.0 ~ 200.0 % in 0.1 %

Initial value: 150.0 % (HD), 120.0 % (ND)
Program the level for overload restriction of the VFD rated current
