Cause
DDCS (fiber optic) communication
between drive and external controller
is lost.
Master/follower communication is
lost.
The supply unit (or other converter)
connected to the inverter unit has
generated a fault.
The supply unit was not ready (ie. the
main contactor/breaker could not be
closed) within expected time.
Selected signal has fallen below the
user underload curve.
Selected signal has exceeded the user
overload curve.
An analog signal is outside the limits
specified for the analog input.
Fault generated by the signal
supervision 1 function.
Fault generated by the signal
supervision 2 function.
Fault generated by the signal
supervision 3 function.
Fault in external device 1.
What to do
Check status of controller. See user
documentation of controller.
Check settings of parameter group
DDCS communication.
Check cable connections. If necessary,
replace cables.
See A7CB M/F comm loss (page
The auxiliary code specifies the
original fault code in the supply unit
control program. See section
codes for line-side converter
faults (page 700).
Check that communication to the
supply unit has been activated by
95.20 HW options word
Check setting of parameter
max charging time.
Check that the supply unit is enabled,
allowed to start, and can be controlled
by the inverter unit (eg. not in local
control mode).
See A8BF ULC underload (page
See A8BE ULC overload (page
Check the auxiliary code (format XXXX
XYZZ). "Y" specifies the location of the
input (0: Control unit, 1: I/O extension
module 1, 2: I/O extension module 2,
3: I/O extension module 3). "ZZ"
specifies the limit (01: AI1 under
minimum, 02: AI1 above maximum, 03:
AI2 under minimum, 04: AI2 above
maximum).
Check signal level at the analog input.
Check the wiring connected to the
input.
Check the minimum and maximum
limits of the input in parameter group
12 Standard AI.
Check the source of the fault
(parameter 32.7 Supervision 1
Check the source of the fault
(parameter 32.17 Supervision 2
Check the source of the fault
(parameter 32.27 Supervision 3
Check the external device.
Check setting of parameter
