Fault
Cause
Remedy
F7995: Pole position identifi-
cation not successful
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The pole position identification routine was
unsuccessful.
Contact the Hotline.
F30001: Power unit: Over-
current
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The power unit has detected an overcur-
rent condition.
• Closed-loop control is incorrectly pa-
rameterized.
• Motor has a short-circuit or fault to
ground (frame).
• Power cables are not correctly con-
nected.
• Power cables exceed the maximum
permissible length.
• Power unit defective.
• Line phase interrupted.
•
Check the motor data - if required, carry out
commissioning.
• Check the motor circuit configuration (star-
delta)
• Check the power cable connections.
• Check the power cables for short-circuit or
ground fault.
• Check the length of the power cables.
• Replace power unit.
• Check the line supply phases.
• Check the external braking resistor connec-
tion.
F30002: DC link voltage,
overvoltage
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The power unit has detected overvoltage
in the DC link.
• Motor regenerates too much energy.
• Device connection voltage too high.
• Line phase interrupted.
•
Increase the ramp-down time.
• Activate the DC link voltage controller.
• Use a braking resistor.
• Increase the current limit of the infeed or
use a larger module.
• Check the device supply voltage.
•
Check the line supply phases.
F30003: DC link voltage,
undervoltage
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The power unit has detected an undervolt-
age condition in the DC link.
• Line supply failure
• Line supply voltage below the permis-
sible value.
• Line supply infeed failed or interrupted.
•
Line phase interrupted.
• Check the line supply voltage.
• Check the line supply infeed and observe
the fault messages relating to it (if there are
any).
• Check the line supply phases.
• Check the line supply voltage setting.
F30004: Drive heat sink
overtemperature
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The temperature of the power unit heat
sink has exceeded the permissible limit
value.
• Insufficient cooling, fan failure.
• Overload.
• Surrounding air temperature too high.
•
Pulse frequency too high.
•
Check whether the fan is running.
• Check the fan elements.
• Check whether the surrounding air temper-
ature is in the permissible range.
• Check the motor load.
• Reduce the pulse frequency if this is higher
than the rated pulse frequency.
F30005: Power unit: Over-
load I
2
t
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The power unit was overloaded.
• The permissible rated power unit cur-
rent was exceeded for an inadmissibly
long time.
• The permissible load duty cycle was
not maintained.
• Reduce the continuous load.
• Adapt the load duty cycle.
• Check the motor and power unit rated cur-
rents.
