Alarms Table 7.D presents a listing and description of the drive alarms. Alarm
status can be viewed by selecting the [Drive Alarm 1/2] parameter.
An active alarm will be indicated by its corresponding bit being set to
high (1). Any high bit (1) can energize CR1-4 (if programmed).

Alarm Bit Alarm Name Description
[Drive
Alarm 1] 0 Bus Charging Precharge of DC bus capacitors is in progress.
1 Hardware Current Limit An alarm will be issued when 220% of drive rated current is reached.
2 Motoring Current Limit The value programmed for [Current Limit] has been exceeded while in the motoring mode.
3 Regenerating Current Limit An alarm will be issued when the value set for [Current Limit] has been exceeded while the motor is
regenerating.
4 Regenerating Voltage Limit Bus limiting is active.
5 Line Loss In Progress An alarm will be issued when the AC incoming voltage drops below 20% of input or a 150 volt drop
takes place.
6 Mtr Overload At the present value of output amps, a motor overload trip will eventually occur.
7 Motor Stalled Drive output frequency folds to 0 Hz and current limit is still active or voltage limit will not allow decel.
8 Ground Warning Ground current exceeds 2 amperes.
9 Auxiliary Input Input circuit is open.
10 Heatsink Temp Temperature of drive heatsink has exceeded its limit.
11 Sync Loss Synchronous motor not at synchronous speed.
12 Phase Loss The DC bus ripple has exceeded the level in [Phase Loss Level].
13 4-20mA Loss 4-20mA signal lost.
14 Motor OL Trip This bit will be high when the motor overload function has integrated high enough to cause a motor
overload fault. This bit is active regardless of the [Motor Overload] state (enabled/disabled).
15 Auto Reset Drive is attempting to reset a fault using [Reset/Run Tries] & [Reset/Run Time].
