284E Trip Status
Description
Action
1
No
Short Circuit
The circuit breaker (140M) has tripped.
Determine cause of trip. Try to reset the circuit
breaker using the disconnect handle. If the
conditions continue, check power wiring or
replace based module. This cannot be disabled.
2
Drive
Controlled
Overload
(Drive Codes 7 and 64)
An excessive motor load exists
1. Reduce load so drive output current does not
exceed the current set by Parameter 133
(Motor OL Current).
2. Verify Parameter 184 (Boost Select) setting.
3. Drive rating of 150% for 1 minute.
4. Reduce load or extend Accel Time two
hundred percent or when 3 seconds has been
exceeded.
3
Drive
Controlled
Phase Short
(Drive Codes 38…43)
1. Phase U, V, or W to Gnd. A phase to ground
fault has been detected between the drive
and motor in this phase.
2. Phase UV, UW, or VW Short. Excessive
current has been detected between these
two output terminals.
Check the wiring between the drive and motor.
Check motor for grounded phase. Check the
motor and drive output terminal wiring for a
shorted condition. Replace drive if fault cannot
be cleared.
4
Drive
Controlled
Ground Fault
(Drive Code 13)
A current path to earth ground has been
detected at one or more of the drive output
terminals.
Check the motor and external wiring to the drive
output terminals for a grounded condition.
5
Drive
Controlled
Stall
(Drive Code 6)
Drive is unable to accelerate motor.
Increase Parameters 139…167 (Accel Time x) or
reduce load so drive output current does not
exceed the current set by Parameter 189
(Current Limit 1).
6
Parameter 23
(PrFlt Reset
Mode)
Control Pwr Loss
(Switched Power)
The ArmorStart has detected a loss of the
control power voltage.
Check control voltage, wiring, and proper
polarity (A1/A2 terminal). Also, check and
replace the control voltage fuse, if necessary.
This fault can be disabled and is disabled by
default.
7
Parameter 23
(PrFlt Reset
Mode)
Input Fault
This error indicates a shorted sensor, shorted
input device, wiring input mistakes, or a blown
output fuse.
If this fault occurs, the offending problem
should be isolated or removed prior to restarting
the system. This fault can be disabled and is
disabled by default.
8
Parameter 23
(PrFlt Reset
Mode)
Over Temperature
This fault is generated when the operating
temperature has been exceeded. This fault
cannot be disabled.
Check for blocked or dirty heat sink fins. Verify
that ambient temperature has not exceeded
40°C (104°F).
1. Clear the fault or cycle power to the drive.
9
Drive
Controlled
Over Current
(Drive Codes 12 and 63)
The drive output current has exceeded the
hardware current limit.
Check programming. Check for excess load,
improper Parameter 184 (Boost Select) setting.
DC brake volts set too high or other causes of
excess current. Parameter 198 (SW Current Trip)
has been exceeded, check load requirements
and Parameter 198 setting.
10
Parameter 23
(PrFlt Reset
Mode)
Control Power (24V DC)
Lost (Unswitched
Power)
The 24V DC power supply is below tolerance
threshold.
Check the state of the network power supply
(A3/A1 terminal) and look for media problems.
This fault can be disabled and is disabled by
default.
11
No
Internal Comm
(Drive Code 81)
RS485 (DSI) port stopped communicating.
Clear the fault or cycle power to the drive. If the
problem persists replace the unit.
12
Drive
Controlled
DC Bus Fault
(Drive Codes Reference
3, 4 and 5)
Power Loss - DC bus voltage remained below
85% of nominal. UnderVoltage - DC but voltage
fell below the minimum value. OverVoltage - DC
bus voltage exceeded maximum value.
Monitor the incoming AC line for low voltage or
line power interruption. Check the input fuses.
Monitor the AC line for high line voltage or
transient conditions. Bus overvoltage can also
be caused by motor regeneration. Extend the
decel time or install dynamic brake option.
