12. Access the “Utility” file and press Enter.
13. Access the “Alarms” group and configure the following parameters:
❏
Par 481 [UnderVolt Thresh] - Enter the value at which a drive
under voltage condition will be detected (default = 230V).
❏
Par 584 [OverCurrent Thr] - Enter the value at which a drive
over current condition will be detected (default = 175%). The
threshold level should be at least 10% above the selected
operating current limit (Par 7 [Current Limit]).
14. Access the “Input & Output” file and press Enter.
15. Access the “Analog Inputs” group and 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). Refer
to
DIP Switch and Jumper Settings on page 1-32
❍
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”.
16. Access the “Digital Inputs” group and configure the following
parameters:
❏
Par 1391 [ContactorControl] - Select the type of contactor(s)
used with the drive: 1 “Contactor” (default, AC input or DC
output contactor), 2 “CoDB” (AC input or DC output
contactor and dynamic brake contactor), or 0 “None”.
Note: If you select 0 “None” for Par 1391 [ContactorControl], a
“CntactrCflct” alarm will display. The alarm will be resolved
and automatically clear when you complete the Digital Output
configuration below.
Note: If Par 1391 [ContactorControl] is set to 1 or 2, an
Auxiliary Status contactor must be wired to a digital input
(default for digital input 8).
❏
Par 140 [Digital In8 Sel] - If a contactor is NOT used, set to
other than 31 “Contactor” (e.g., 0 “Not Used”).
❏
If an auxiliary status contactor is wired to a digital input, set the
appropriate [Digital Inx Sel] parameter to 31 “Contactor”.
