Alarm Descriptions
Tab le 3 provides a list of alarm messages and descriptions of the cause of the
alarm.
Table 3 - Alarm Descriptions and Actions
Alarm
No.
Type
(1)
Description
Analog in Loss 5 1 An analog input is configured for “Alarm” on signal loss and signal loss has occurred.
Bipolar
Conflict
20 2 Parameter 190 [Direction Mode] is set to “Bipolar” or “Reverse Dis” and one or more of the
following digital input functions is configured:
“Fwd/Reverse”, “Run Forward”, “Run Reverse”, “Jog Forward”, or “Jog Reverse”.
Decel Inhibit 10 1 Drive is being inhibited from decelerating.
Dig In
ConflictA
17 2 Digital input functions are in conflict. Combinations marked with an “X” will cause an alarm.
Dig In
ConflictB
18 2 A digital Start input has been configured without a Stop input or other functions are in
conflict. Combinations that conflict are marked with an “X” and will cause an alarm.
Dig In
ConflictC
19 2 More than one physical input has been configured to the same input function. Multiple
configurations are not allowed for the following input functions.
Drive OL Level
1
8 1 The calculated IGBT temperature requires a reduction in PWM frequency. If [Drive OL Mode] is
disabled and the load is not reduced, an overload fault eventually occur.
Drive OL Level
2
9 1 The calculated IGBT temperature requires a reduction in Current Limit. If [Drive OL Mode] is
disabled and the load is not reduced, an overload fault eventually occur.
FluxAmpsRef
Rang
26 2 The calculated or measured Flux Amps value is not within the expected range. Verify motor
data and rerun motor tests.
Ground Warn 15 1 Ground current has exceeded the level set in [Gnd Warn Level].
In Phase Loss 13 1 The DC bus ripple has exceeded the level in [Phase Loss Level].
IntDBRes
OvrHeat
6 1 The drive has temporarily disabled the DB regulator because the resistor temperature has
exceeded a predetermined value.
