Fault
Cause
Remedy
F7860: External fault 1
Reaction: OFF2
Acknowledgement:
IMMEDIATELY (POWER
ON)
The signal "external fault 1" was triggered.
• Restart the drive.
• Restore the drive to its factory default set-
tings.
F7900: Motor blocked/speed
controller at its limit
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The servo motor has been operating at the
torque limit longer than 1s and below the
speed threshold of 120 rpm.
This signal can also be initiated if the
speed actual value is oscillating and the
speed controller output repeatedly goes to
its limit.
•
Check whether the servo motor can rotate
freely or not.
• Check the torque limit.
• Check the inversion of the actual value.
• Check the motor encoder connection.
• Check the encoder pulse number.
F7901: Motor overspeed
Reaction: OFF2
Acknowledgement:
IMMEDIATELY
The maximum permissible speed has
been exceeded.
Check and correct the maximum speed
(p1082).
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.
