ADV SETUP
[PLL Max Error] — P.071
Maximum allowable change in line period per
AC line cycle. This input should only be
increased when drive power is supplied by a
source that cannot maintain a suitable fixed
frequency output (such as an alternator) to
prevent line synchronization-related faults.

[Spd LeadLag Freq] — P.072
If Lead/Lag is selected in [Spd Leadlag
Type], this parameter represents the low lead
frequency. If [Spd Leadlag Type] is set to
Bypass, this parameter has no effect. If
Lag/Lead is selected, it represents the low lag
frequency.

[Spd LeadLag Rato] — P.073
Sets the ratio of low to high break frequencies
for the lead/lag block. For example, if this
parameter is set to 10, the high break
frequency will be 10 times the low break
frequency — specified by [Spd Leadlag
Freq]. If [Spd Leadlag Type] is set to
Bypass, this parameter has no effect.

[Spd LeadLag Type] — P.074
Determines if the lead/lag block will act upon
the speed loop feedback signal. If On, the
lead/lag block is bypassed and the feedback
signal is used directly by the speed loop
summing junction.
