A4B0
Excess temperature
Power unit module
temperature is
excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A4B1
Excess temperature
difference
High temperature
difference between the
IGBTs of different
phases.
Check the motor cabling.
Check cooling of drive module(s).
A4B2
PCB space cooling
Temperature difference
between ambient and
drive module PCB space
is excessive.
Check the cooling fan inside the PCB
space.
Check the auxiliary code.
A4F6
IGBT temperature
Drive IGBT temperature
is excessive.
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check motor power against drive
power.
A580
PU communication
Communication errors
detected between the
drive control unit and the
power unit.
Check the connections between the
drive control unit and the power unit.
A581
Fan
Cooling fan stuck or
disconnected.
Check fan operation and connection.
Replace fan if faulty.
A582
Auxiliary fan missing
An auxiliary cooling fan
(connected to the fan
connectors on the control
unit) is stuck or
disconnected.
Check auxiliary fan(s) and
connection(s). Replace faulty fan.
Make sure the front cover of the drive
module is in place and tightened. If the
commissioning of the drive requires
that the cover is off, this warning will be
generated even if the corresponding
fault is defeated. See fault
(page
).
A5A0
Safe torque off
Programmable warning:
Safe torque off function
is active, i.e. safety
circuit signal(s)
connected to connector
XSTO is lost.
Check safety circuit connections. For
more information, see appropriate
drive hardware manual and
description of parameter
