Possible Causes or Remedies
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.
