E70 DriveHardFault (NV
Mem Init)
Non-volatile memory is corrupt due to control board
software error. Load default parameters, save
to non-volatile memory, and
recycle power or reset the
drive.
E71 DriveHardFault (Mem-
ory Init)
RAM or Flash memory validation failure •
Cycle power.
• If fault persists, replace module.
E72 DriveOvertemp Fault
(Drive Overtemp)
Inverter thermal switch
tripped The fan on the IAM or an
AM failed. Replace the failed module.
The cabinet ambient
temperature is above rat-
ing. Check the cabinet tempera-
ture.
The machine duty cycle
requires an RMS current
exceeding the continu-
ous rating of the control-
ler. Change the command profile
to reduce speed or increase
time.
The airflow access to the
Kinetix 2000 system is
limited or blocked. Check airflow and re-route
cables away from the Kinetix
2000 system.
E73 Communicate (Back-
plane Comm)
Power rail CAN communications failed. Check module for proper
mount.
Power rail connection shorted or open. Check power rail and module
for foreign objects.
E74 DriveOvercurrent
Fault
(Bus OverCur-
rent)
DC link current exceeds
rating Motor or transmission
malfunction. •
Check for proper motor sizing.
• Check/replace transmission
device.
• Check/replace motor.
IAM not properly sized. •
Check for proper IAM sizing.
• Install larger kW rated IAM.
E75 DriveOvervoltage
Fault
(Shunt Time Out)
The IAM, AM, or SM has exceeded its shunt resis-
tor continuous rating. •
Use a properly sized shunt or
modify duty cycle of the applica-
tion.
• System uses internal shunt and
requires external shunt for addi-
tional capacity.
E76 DriveHardFault (CAN
Init)
DPI hardware initializa-
tion fault detected Control board hardware
failure. • Reset System.
• If fault persists, replace sys-
tem module.
E78 DriveHardFault (SER-
COS Init)
Control hardware fault detected. •
Cycle power.
• If fault persists, replace module.
E79 DriveOvervoltage
Fault
(Shunt Module
Flt)
Shunt module temperature fault LED indicator is
steady red. Refer to Temperature Fault
LED Indicator on page 141.
Shunt module shunt fault LED indicator is steady
red. Refer to Shunt Fault LED Indi-
cator on page 141.
Module missing from power rail. • Install missing module on
power rail.
• Fill empty slot with slot filler
module.
E80 DriveHardFault (CPLD
Flt)
Control hardware fault detected. Replace module.
E81 DriveHardFault (Com-
mon Bus Flt)
Follower IAM detected ac input power being
applied. Remove ac input power con-
nections from follower IAM.
