ArmorStart
Drive Controlled
1
Short (140M)
—
The circuit breaker has tripped. Try to reset the breaker. If the condition continues check the 
power wiring. This fault cannot be disabled.
2
—
Overload Fault
(Drive Error Codes 7 and 64)
An excessive motor load exists. Reduce load so drive output current does not exceed the current 
set by Parameter 133 (Motor OL Current) and verify Parameter 184 (Boost Select) setting. 
Reduce load or extend Accel Time. This fault cannot be disabled.
3
—
Phase Short (Drive Error Codes 
41…43)
The ArmorStart
has detected a phase short. Excessive current has been detected between two
of the output terminals. Check the motor for a shorted condition. Replace starter module if fault 
cannot be cleared. This fault cannot be disabled.
4
—
Ground Fault (Drive Error Codes 
13, 38…40)
A current path to earth has been detected at or more of the drive output terminals or a phase to 
ground fault has been detected between the drive and motor in this phase. Check the motor for 
a grounded condition. Replace starter module if fault cannot be cleared. This fault cannot be 
disabled.
5
—
Motor Stalled
(Drive Error Code 6)
Drive is unable to accelerate motor. Increase Parameter 139 and/or 167 (Accel Time x) or reduce 
load so drive output current does not exceed the current by Parameter 189. This fault cannot be 
disabled.
6
Control 
Power
—
The ArmorStart has detected a loss of the control power voltage. Check control voltage, wiring, 
and proper polarity. Also check and replace control voltage fuse, if necessary. This fault can be 
disabled and is disabled by default.
7
I/O Fault
—
Depending on the types of modules in the configuration this error could be generated by a 
shorted sensor, shorted input device, wiring 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
—
Heatsink Overtemperature 
(Drive Error Code 8)
Heatsink temperature exceeds a predefined value. Verify that ambient temperature has not 
exceeded. This fault cannot be disabled. Replace internal fan.
9
—
Over-Current 
(Drive Error Codes 12 and 63)
The ArmorStart has detected a voltage imbalance. Check the power system and correct if 
necessary. This fault cannot be disabled.
10
DNet Power 
Loss
—
DeviceNet power has been lost or has dropped below the 12V threshold. Check the state of the 
network power supply and look for DeviceNet media problems. This fault can be disabled and is 
disabled by default.
11
Internal 
Comm
—
This fault occurs when communications between the main board the drive is lost. This fault 
cannot be disabled. 
12
—
DC Bus Fault
(Drive Error Codes 3, 4, and 5)
DC bus voltage remained below 85% of nominal. DC bus voltage fell below the minimum value. 
DC bus voltage exceeded maximum value. Monitor the incoming AC line for low voltage or line 
power interruption. Check 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 a starter module with the 
dynamic brake option. This fault cannot be disabled.
13
—
EEPROM Fault/Internal Comm 
Flt 
(Drive Error Codes 81 and 100)
This is a major fault, which renders the ArmorStart inoperable. Possible causes of this fault are 
transients induced during EEprom storage routines. If the fault was initiated by a transient, 
power cycling should clear the problem. Otherwise replacement of the starter module may be 
required. This fault cannot be disabled.
14
—
Hardware Fault
(Drive Error Codes 2, 70, and 
122)
This fault indicates that a serious hardware problem exists. Check for a base/starter module 
mismatch. Auxiliary input interlock is open. Failure has been detected in the drive power 
section. Failure has been detected in the Drive control and I/O section. Cycle power and replace 
drive if fault cannot be cleared. This fault cannot be disabled.
15
—
Auto Restart Tries
(Drive Error Code 33)
Drive unsuccessfully attempted to reset a fault and resume running for the programmed number 
of Parameter 192 (Auto RstrtTries). Correct the cause of the fault. This fault cannot be disabled.
16
—
Miscellaneous Fault
This fault is actually the logical OR of the drive’s Auxiliary Input fault (Fault Code 2), Heatsink 
Overtemperature fault (Fault Code 8), Parameter Defaulted fault (Fault Code 48), and SVC 
Autotune fault (Fault Code 80). This fault cannot be disabled.
