Chapter 7 Troubleshooting the Kinetix 6000 Drive System
DriveHardFault
(Memory Init)
E71 RAM or flash memory validation failure. SHUTDOWN No
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.
SHUTDOWN
Drive Thermal
Yes
Communicate
(Backplane Comm)
E73 Power rail backplane CAN communication failed. STOP MOTION No
DriveOvercurrentFault
(Bus OverCurrent)
E74 The converter has exceeded its converter rating. SHUTDOWN 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.
SHUTDOWN No
DriveHardFault
(Can Init)
E76 Either DPI or backplane CAN initialization failure. SHUTDOWN 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.
SHUTDOWN No
DriveHardFault
SERCOS Init
E78 Control hardware fault detected. SHUTDOWN No
DriveOvervoltageFault
(Shunt Module Flt)
E79
Power rail mounted shunt module fault. Displayed on IAM module
seven-segment fault status indicator.
SHUTDOWN No
HardwareFault
(CPLD Flt)
E80 Control hardware fault detected. SHUTDOWN No
HardwareFault
(Common Bus Flt)
E81
Common-bus follower IAM module detected AC input power being
applied.
SHUTDOWN No
HardwareFault
(Pre-charge Timeout Flt)
E90 Pre-charge resistor power exceeds the resistor rating. SHUTDOWN No
(1) The Logix Motor Thermal Fault Action is tied to the motor thermostat fault. If this is set to Shutdown or Disable (in Logix), the drive will fold 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 will not fold back the
current. The I
2
T calculation never generates a fault.
(2) The Logix Drive Thermal Fault Action is tied to the drive thermostat fault. The drive will always fold back the current when the I
2
T calculation indicates that the drive has
exceeded 110% of its rating. The I
2
T calculation never generates a fault.
