LX - Special Function Parameters
This parameter sets the amount that the rotor learn value can differ from the
average value. If the difference between the learned position and the average
is greater than this setting a Rotor Learn Deviation Error will be triggered.
This function is only active when Encoder Deviation Enable LX23 = On
With Error and Rotor Detection Mode LE07 = NOP.
When LE07 Rotor Detection Mode = NOP this parameter controls if each rotor
learn value will be compared with the average after each rotor learn.
Setting: Description: NUM
OFF No Function 0
On with Error When LE07 = NOP (1) this function
will keep track of the running average
of the learned pole position values
and compare that to the new pole
position. If the average and the new
pole position differ by greater than
LX22 then Rotor Learn Deviation Error
will be triggered.
If the Rotor Learn Deviation Error is
triggered 10 times a Rotor Learn COM
Error will be triggered.

Default = Off (0)
This parameter works in conjunction with LX21 and is used to set the distance
threshold at which the Unintended Movement event will occur. Refer to section
12.2 for function testing.
Min. value - 1.96 in. / 50mm
Max. value - 19.6 in. / 500mm
Default value - 7.875 in. / 200mm
This parameter activates advanced phase detection to prevent the drive from
continuing to modulate in the event that the DC bus voltage ripple is less than
200Hz. The drive will trigger a phase failure error.
This parameter allows the LS01 Leveling Speed upper limit to be increased
from 25FPM to 59FPM.
