Cause
DDCS (fiber optic)
communication between
60.79
converters (for example, the
inverter unit and the supply
unit) is lost.
DDCS (fiber optic)
communication between drive
and external controller is lost.
60.59
Master/follower
communication is lost.
60.09
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.
What to do
Check status of other converter
(parameters 06.36 and 06.39).
Check settings of parameter group
DDCS communication. Check the
corresponding settings in the control
program of the other converter.
Check cable connections. If necessary,
replace cables.
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 MF comm loss
Check fault status of supply unit (or other
converter).
Refer to the firmware manual of the
supply unit.
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 warning
487).
See A8BE ULC overload warning
486).
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
Standard AI.
Check the source of the fault (parameter
32.07 Supervision 1 signal).
Check the source of the fault (parameter
32.17 Supervision 2 signal).
