When a fault is detected, it is stored in the Fault History. The last faults
and warnings are stored with the time the fault was detected.
WARNING! After a fault reset, the ACA 635 will start if the start signal
is on. Before the reset, switch off the external start signal or ensure that
it is safe to start.
The Fault History can be viewed by pressing
Signal Display Mode. The Fault History can then be scrolled with

can be cleared by pressing the RESET key.
The tables below show the warning and fault messages.
Cause
The ACS 600 internal temperature is
excessive. A warning is given if the converter
module temperature exceeds 115 °C.
I/O reference 4...20 mA is below 3.1 mA when
Par. 13.06 MINIMUM AI2 or Par. 13.10
MINIMUM AI3 is set to 4 mA.
Communication break detected on CH0
receive.
(can be deactivated: see Parameter 70.04)

I .
1base(10s/60s)
Digital input DI5 is OFF (0).

Impedance between a live part (e.g. phase
conductor, DC link, motor cable or motor) and
earth/ground is too low.

What to do
Check ambient conditions.
Check air flow and fan operation.
Check heatsink fins for dust pick-up.
Check line current against unit current.
Check for proper analogue control signal level.
Check the control wiring.
Check the fibre optic cables between the
NAMC board and overriding system (or
fieldbus adapter). Test with new fibre optic
cables.
Check that the CH0 node address (Par. 70.01
CH0 NODE ADDR) is correct in the ISU.
Check the status of the fieldbus adapter. See
appropriate fieldbus adapter manual.
Check parameter settings of Group 51, if a
fieldbus adapter is present. Check the
connections between the fieldbus and the
adapter.
Check that the bus master is communicating
and correctly configured.
Limit inverter actual power or lower the
reactive power percentage in Par. 24.01 Q
POWER REF.
Check the function indicated via digital input
DI5.
Check motors.
Check motor cables.
Check ISU.
Check inverter(s).
Check AC filter.
