ALARMS

Alarms are advisory in nature. These indicate a problem
has been detected by the VFD's diagnostics but this prob-
lem will not require that the VFD and its motor be shut
down. Typical fault condition on the 2-Speed Indoor Fan
Motor System application might be loose connections at the
VFD terminal board or damaged conductors between the
Fan Speed Board connector J2 and the VFD terminal strip.
See Table 38 for a full list.

CLEAR THE ALARM LED

Shut off power to the VFD for five minutes. Restore power
and recheck the GREEN LED. If this LED is still flashing,
then connect the accessory remote display keypad kit. Use
Table 38 to determine if the alarm requires any corrective
action (action is not always required) and address the root
cause of the problem.
If diagnostics troubleshooting has determined that the drive
is defective during the warranty period, contact us.

The change in direction being attempted is not allowed. Do not attempt to change the direction of motor
rotation, or Change parameter 1003 DIRECTION to allow direction change (if reverse operation is safe).
Field bus communication has timed out. Check fault setup (3018 COMM FAULT FUNC and 3019 COMM
FAULT TIME). Check communication settings (Group 51 or 53 as appropriate). Check for poor connections
and/or noise on line.
Analog input 1 is lost, or value is less than the minimum setting. Check input source and connections. Check
the parameter that sets the minimum (3021) and the parameter that sets the Alarm/Fault operation (3001).
Analog input 2 is lost, or value is less than the minimum setting. Check input source and connections. Check
parameter that sets the minimum (3022) and the parameter that sets the Alarm/Fault operation (3001).
Panel communication is lost and either the VFD is in local control mode (the control panel displays HAND),
or the VFD is in remote control mode (AUTO) and is parameterized to accept start/stop, direction or
reference from the control panel. To correct, check the communication lines and connections, Parameter
3002 PANEL LOSS, and parameters in groups 10 COMMAND INPUTS and 11 REFERENCE SELECT (if
drive operation is REM).
Reserved
Motor is hot, based on either the VFD estimate or on temperature feedback. This alarm warns that a Motor
Overload fault trip may be near. Check for overloaded motor. Adjust the parameters used for the estimate
(3005 - 3009). Check the temperature sensors and Group 35 parameters.
Motor load is lower than expected. This alarm warns that a Motor Underload fault trip may be near. Check
that the motor and drive ratings match (motor is NOT undersized for the drive). Check the settings on
parameters 3013 to 3015.
Motor is operating in the stall region. This alarm warns that a Motor Stall fault trip may be near.
This alarm warns that the drive is about to perform an automatic fault reset, which may start the motor. To
control automatic reset, use parameter group 31 (AUTOMATIC RESET).
This alarm warns that the PFA autochange function is active. To control PFA, use parameter group 81 (PFA)
and the Pump Alternation macro.
Specifications subject to change without notice.

FAULTS

A fault is a significant internal situation for the VFD or its mo-
tor. If the motor was running when the fault was detected, it
was shutdown. See Table 39 for a full list of faults, display
codes, and recommended actions.
Clear the Fault LED
The recommended corrective action for faults is shown in
Table 39. The VFD can also be reset to remove the fault. If
an external source for a start command is selected and is
active, the VFD may start immediately after fault reset.
Connect the accessory remote display keypad kit. To reset
a fault indicated by a flashing red LED, turn off the power for
5 minutes. To reset a fault indicated by a red LED (not flash-
ing), press RESET from the control panel or turn off the
power for 5 minutes. Depending on the value of parameter
1604 (FAULT RESET SELECT), digital input or serial com-
munication could also be used to reset the drive. When the
fault has been corrected, the motor can be started.
