parameters. See Table
3-57.
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.
1 Cyc Protect integ gain 7080 0.0025 0.0 1.0
Gain of integral regulator for
detecting excessive input
reactive current. Output of this
regulator is used to fault the
drive in case high reactive
currents flow in the input (other
than the instant when MV is
applied to the drive). Adjust the
gain to change the response to
high reactive currents.
1 Cycle Protect Limit 7081 % 50.0 0.0 100.0
Integrator output level at which
drive issues a 1 Cycle Protect
Fault.
Xformer tap setting 7050 % 0
Choose from the {-5,0,+5%}
settings to match transformer tap
setting.
Xformer thermal gain 7090 0.0133 0.0 1.0
Gain of integral regulator to
limit input current to 105% of its
rated value.
Xformer protection const 7100 0.5 0.0 10.0
Gain to adjust model of input
transformer. Use the default
value of 0.375.
Phase Imbalance Limit 7105 % 40.0 0.0 100.0
Input current level (as a percent
of Rated Input Current) above
which Input Phase Imbalance
Alarm is issued.
Ground Fault Limit 7106 % 40.0 0.0 100.0
Level above which drive issues
an Input Ground Fault Alarm.
Ground Fault Time Const 7107 sec 0.2 0.001 2.0
Time constant of filter used for
averaging input neutral voltage.
