Problem or Symptom
Non-volatile memory is corrupt due to control board
software error.
RAM or Flash memory validation failure
Inverter thermal switch
tripped
Power rail CAN communications failed.
Power rail connection shorted or open.
DC link current exceeds
rating
The IAM, AM, or SM has exceeded its shunt resis-
tor continuous rating.
DPI hardware initializa-
tion fault detected
Control hardware fault detected.
Shunt module temperature fault LED indicator is
steady red.
Shunt module shunt fault LED indicator is steady
red.
Module missing from power rail.
Control hardware fault detected.
Follower IAM detected ac input power being
applied.
Potential Cause
The fan on the IAM or an
AM failed.
The cabinet ambient
temperature is above rat-
ing.
The machine duty cycle
requires an RMS current
exceeding the continu-
ous rating of the control-
ler.
The airflow access to the
Kinetix 2000 system is
limited or blocked.
Motor or transmission
malfunction.
IAM not properly sized.
Control board hardware
failure.
Troubleshooting
Possible Resolution
Load default parameters, save
to non-volatile memory, and
recycle power or reset the
drive.
•
Cycle power.
• If fault persists, replace module.
Replace the failed module.
Check the cabinet tempera-
ture.
Change the command profile
to reduce speed or increase
time.
Check airflow and re-route
cables away from the Kinetix
2000 system.
Check module for proper
mount.
Check power rail and module
for foreign objects.
•
Check for proper motor sizing.
• Check/replace transmission
device.
• Check/replace motor.
•
Check for proper IAM sizing.
• Install larger kW rated IAM.
•
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.
• Reset System.
• If fault persists, replace sys-
tem module.
•
Cycle power.
• If fault persists, replace module.
Refer to Temperature Fault
LED Indicator on page 141.
Refer to Shunt Fault LED Indi-
cator on page 141.
• Install missing module on
power rail.
• Fill empty slot with slot filler
module.
Replace module.
Remove ac input power con-
nections from follower IAM.
