DriveOvertempFault
(Drive Overtemp)
E72
Inverter temperature limit exceeded.
Firmware I
2
t protection does not generate a fault, rather it dynamically folds back
current when 110% of drive rating is reached. Setting the Drive Thermal fault action
to Status Only or Stop Motion bypasses the foldback behavior and allows the fault to
occur.
N/A
Yes
Drive Thermal
Communicate
(Backplane Comm)
E73
Power rail backplane CAN communication failed.
Decel/Disable
No
DriveOvercurrentFault
(Bus OverCurrent)
E74
The converter has exceeded its converter rating.
Coast/Disable (open
contactor enable relay)
No
DriveOvervoltageFault
(Shunt Time Out)
E75
The IAM/AM module or shunt module has exceeded its shunt resistor continuous
rating. SHUTDOWN for IAM module, DISABLE for AM module. IAM module provides
fault handling for shunt module.
Coast/Disable (open
contactor enable relay)
No
DriveHardFault
(Can Init)
E76
Either DPI or backplane CAN initialization failure.
Coast/Disable (open
contactor enable relay)
No
DriveHardFault
(Module Mismatch)
E77
Generated by IAM module if the power rating of an AM module on the same power
rail does not match with IAM module input power rating.
Coast/Disable (open
contactor enable relay)
No
DriveHardFault
Sercos Init
E78
Control hardware fault detected.
Coast/Disable (open
contactor enable relay)
No
DriveOvervoltageFault
(Shunt Module Flt)
E79
Power rail mounted shunt module fault. Displayed on IAM module seven-segment
fault status indicator.
Coast/Disable (open
contactor enable relay)
No
HardwareFault
(CPLD Flt)
E80
Control hardware fault detected.
Coast/Disable (open
contactor enable relay)
No
HardwareFault
(Common Bus Flt)
E81
Common-bus follower IAM module detected AC input power being applied.
Coast/Disable (open
contactor enable relay)
No
HardwareFault
(Pre-charge Timeout Flt)
E90
Pre-charge resistor power exceeds the resistor rating.
Coast/Disable (open
contactor enable relay)
No
IPIMFault
(IPIM Module Flt)
E95
A fault has occurred in one or more IPIM modules on the power rail.
Coast/Disable (open
contactor enable relay)
No
(1) The Logix5000 Motor Thermal Fault Action is tied to the motor thermostat fault. If this is set to Shutdown or Disable (in controller), the drive folds back the current when the I
2
T calculation indicates that
the motor temperature has exceeded 10% of its rated temperature. If it is set to Stop Motion or Status Only, the drive does not fold back the current. The I
2
T calculation never generates a fault.
(2) The Logix5000 Drive Thermal Fault Action is tied to the drive thermostat fault. The drive always folds back the current when the I
2
T calculation indicates that the drive has exceeded 110% of its rating. The
I

T calculation never generates a fault.
