Faults / Events
When faults occurIN, the inverter is no longer able to control the drive and is disabled. An entry is made in the fault memory
(
E40
/
E41
), and relay 1 (ready for operation) releases. If installed when the fault occurs, the Parabox is written automatically.
Certain events (cf. last column of the table below) can be declared via FDS Tool as faults, messages, warnings or not effective.

FDS
Tool*
45: OTempMot.i
2
t
The motor is overloaded.
√
46: Low voltage
DC-link voltage is below the limit value set in
A35
.
•
Drops in the power supply.
•
Acceleration times are too short (ramps,
D ..
).
•
Fault is also triggered when option board is used (24 V external supply) when the
power supply drops while the enable is active.
•
Failure of a phase with 3~ connection.
√
√
47: Device overl.
The maximum torque permitted for static operation has been exceeded. The
permissible torque is limited by parameters
C03
and
C04
and the possible torque
limitation via analog input. See
F20
=2 or
F25
=2 and chap. 9.2.
√
√
48: Accel.overl.
Same as
"47:Device overload"
except for an acceleration procedure. M-Max 2 (
C04
) is
permitted for the acceleration procedure with "cycle characteristic" startup (
C20
=2).
√
√
49: Decel.overl.
Same as
"47:Device overlaod"
except for a deceleration procedure
√
√
50: Operat.area
The operating area defined under
C41
to
C46
has been exited. See also chap. 9.3.
√
√
51: Refused
Only for positioning (
C60
=2).
Posi.start
or
posi.step
was not accepted and the RV-
reached signal ("in position") is reset.
•
Destination position is located outside software limit switches
I50
and
I51
.
•
In non-referenced status (
I86
=0), no absolute positions (e.g.,
J11
=1) are traveled to.
•
The direction of rotation in the current process block is not the same as the
permissible direction
I04
.
√
√
52: Communication
•
Fault during communication between inverter and FDS Tool during remote control
via PC
•
Communication fault during fieldbus operation (Kommubox)
√
53: Stop input
A limit switch connected via a BE input has been triggered, or the traversing area
permitted by software limit switches
I50
and
I51
has been exited. During referencing at
the limit switch (
I30
=1), a reversal of the limit switches will cause a fault.
54: Follow. error
The maximum following error (i.e., deviation between actual position and reference
value position) permitted by
I21
has been exceeded.
Possible causes: Motor overload, too much acceleration or blockage
√
55: OptionBoard
•
When option board
EA4001 (EA-4000)
or
GB4001 (GB-4000)
is used, the external
24 V voltage is not present or the card is defective. No fault if enable is deactivated.
•
No option board found (e.g., if
B26
=1:Option (X20)
When functions of an option board (binary inputs, encoder) are parameterized, an
option board is requested. Check parameters
B26
,
G27
,
I02
. Check
F31
to
F35
and
F60
to
F68
and change to "
0:inactive
" if necessary.
The events checked in the "FDS Tool" column can be parameterized with FDS Tool as messages, warnings or faults in the
group
U..
protective functions.
Acknowledgment of faults:
•
Enable:
Change from low to high level on the enable input.
Always available.
•
Esc
-key
(only if
A31
=1).
Caution!
Drive starts
•
Auto-reset
(only if
A32
=1).
up
immediately!
•
Binary input
(
F31
to
F35
=13).
Parameters
E40
and
E41
can be used to scan the last 10 faults (i.e., value 1 is the last fault). FDS Tool can then be used to
indicate under "
S..
fault memory" many details on the last faults which occurred.
