Cause
Drive module temperature is
excessive.
Power unit module
temperature is excessive.
High temperature difference
between the IGBTs of
different phases.
Drive IGBT temperature is
excessive.
Communication errors
detected between the drive
control unit and the power
unit.
Initialization of the drive
hardware.
Drive hardware setup is
initializing.
Initializing HW settings for
the first time.
Safe torque off function is
active, ie safety circuit
signal(s) connected to
connector STO is lost.
Problem with internal
temperature measurement
of the drive.
Power unit power supply
failure.
Communication errors
detected between the drive
control unit and the power
unit.
Measurement circuit fault.
What to do
Check ambient temperature. If it
exceeds 50 °C /122 °F, ensure that load
current does not exceed derated load
capacity of drive. See chapter
Technical data
, section
hardware manual of the drive.
Check drive module cooling air flow
and fan operation.
Check inside of cabinet and heatsink
of drive module for dust pick-up. Clean
whenever necessary.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the motor cabling.
Check cooling of drive module(s).
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
Check the connections between the
drive control unit and the power unit.
Check the auxiliary code. See actions
for
each code below.
Wait for the setup to initialize.
Wait for the setup to initialize.
Check safety circuit connections. For
