Ixternal fault
Cause
Short
circuit/earth
fault at the
motor side
e.g.
by
-
defective motor cable
-
contact of motor windings
-
contact between motor
housing and winding
Frequent
or too long
accelerations with overcurrent
Permanent overload with motor
current
>
110% rafed current.
The permissible output power
was reduced to 12 or 16 kHz by
increasing the chopper
frequency
Thermal overlaod of the motor,
caused
by
e.g.
-
non-permissible continuous
current
-
frequent or too long
accelerations
Heatsink too hot,
e.g.
because,
-
Ambient temperature too high
-
Heatsink strongly polluted
-
Incorrect mounting
Motor is overheated
PTC connecting cable
interrupted
PTC input open
Supply of automation module
switched
off or defective
Connection to automation
module interrupted
Dverload/Short-circuit
at
terminal 20
115-V
supply defective
Strong interferences on control
cables
PE loops in the
witing
After mains connection a
modified Software
version
was
found.
Factory settlngs were loaded
automatically.
When Parameter sets 1 to 4
were loaded, a fault was found.
Factory settings were loaded
automatically.
Signal via digital input ‘fault
indication”
Incorrect programming of the
input “fault indication”
Remedy
Check motor cable for
short-
circuit
Separate motor cable from
Controller and check insulation
between U-V-W and PE
Check motor
Check dimensioning of the
drive
If necessaty, set
Lt
monitoring
(Cl 19, Cl 20) to increased or
maximum permanent power
(observe ambient temperature)
Check setting of the chopper
frequency (CO1 8)
Check dimensioning of the drive
Enter correct motor size
(COSS),
If
necessary,
switch
off
monitoring (Cl 19, Cl 20)

to cool and
rnsure

Ventilation
Check ambient temperature in
the control cabinet
. Clean heatsink
Change mounting
Check dimensioning of the drive
