Parameter ID Unit Default Min Max Description
Single phasing 7010 Submenu Access the single phasing protection pa‐
rameters. See Table Single Phasing Menu
(7010).
Undervoltage
prop gain 7060 0.0 0.0 10.0 Under voltage PI regulator proportional
gain term.
Undervoltage
integ gain 7070 0.001 0.0 1.0 Undervoltage PI regulator integral gain
term.
UV Flux Reduc‐
tion gain 7075 0.05 0.0 0.5 Undervoltage Flux Reduction Integrator
regulator gain term. Rolls back flux de‐
mand on synchronous motors when up
against the modulation index clamp limit.
UV Flux Recov‐
ery gain 7076 0.01 0.0 0.5 Undervoltage Flux Recovery Integrator
regulator gain term.
MI Lim Spd Re‐
duce gain 7077 0.01 0.0 0.5 Overmodulation Speed Reduction Integra‐
tor regulator gain term. Rolls back speed
demand on PMM motors when up against
the modulation index clamp limit.
MI Lim Spd Re‐
cover gain 7078 0.01 0.0 0.5 Overmodulation Speed Recovery Integra‐
tor regulator gain term.
1 Cyc Protect in‐
teg gain 7080 0.0025 0.0 1.0 Gain of integral regulator for detecting ex‐
cessive input reactive current. Output of
this regulator is used to fault the drive in
case high reactive currents flow in the in‐
put, other than when MV is applied to the
drive. Adjust the gain to change the re‐
sponse to high reactive currents.
1 Cycle Protect
Limit 7081 % 50.0 0.0 100.0 Set the integrator output level at which
the drive issues a 1 Cycle Protect fault.
Excess Loss Idle 7084 % 5.0 1.0 5.0 Set the excessive drive power loss level
when the drive is idle, in particular when
cell is fast bypassing. The default is 5 % of
input power, which is the hard-coded val‐
ue of previous releases.
Excess Loss Run‐
ning 7086 % 7.0 3.0 12.0 Set the excessive drive power loss level
when the drive is running. The default is
7% of input power, which is the hard-co‐
ded value of previous releases.
Xformer tap set‐
ting 7050 % 1 Choose from settings -5%, 0%, +5%, +10%
to match transformer tap setting.
Xformer ther‐
mal gain 7090 0.0133 0.0 1.0 Gain of integral regulator to limit input
current to 105% of its rated value.
Xformer protec‐
tion const 7100 0.5 0.0 10.0 Gain to adjust model of input transformer.
Use the default value of 0.5.
Phase Imbal‐
ance Limit 7105 % 40.0 0.0 100.0 Set the input current level, as a percent‐
age of rated input current, above which
input phase imbalance alarm is issued.
