20. Access the “Utility” file.
21. Press Enter.
22. Access the “Alarms” group.
23. Configure the following parameters:
❏ Par 481 [UnderVolt Thresh] - Enter the value at which an AC under
voltage condition will be detected by the drive (default = 200V on a
240V AC line and 400V on a 480V AC line). Typically, this value is
approximately 85% of the nominal AC line voltage.
❏ Par 584 [OverCurrent Thr] - Enter the value at which a drive over
current condition will be detected (default = 175%). Set the
threshold level at least 10% above the selected operating current
limit (Par 7 [Current Limit]).
❏ Par 585 [OverSpeed Val] - Enter a value that is 10% above the
maximum speed that the motor will achieve. Typically 10% above
Par 162 [Max Feedback Spd].
24. Access the “Input & Output” file.
25. Press Enter.
26. Access the “Analog Inputs” group.
27. Configure the following:
❏ If you have connected a potentiometer to analog input 1 for a speed
reference:
• Verify that Par 70 [Anlg In1 Sel] is set to 1 “Speed Ref A”
(default).
• Verify that switch S9 and Par 71 [Anlg In1 Config] are
configured to match (voltage versus a current signal). See DIP
Switch and Jumper Settings on page 75
.
• Set Par 72 [Anlg In1 Scale] and Par 74 [Anlg In1 Offset]
appropriately.
❏ If you are using the HIM on the drive cover (Port 1) for the speed
reference, set Par 70 [Anlg In1 Sel] to 0 “Off ”.
