F13100 Know-how protection: Copy
protection error
The know-how protection and the copy protection for the memory card
are active. An error occurred when checking the memory card.
• Insert a suitable memory card and switch the inverter supply voltage
temporarily off and then on again (POWER ON).
• Deactivate the copy protection (p7765).
F13101 Know-how protection: Copy
protection cannot be activated
Insert a valid memory card.
F30001 Overcurrent Check the following:
• Motor data, if required, carry out commissioning
• Motor connection method (Υ / Δ)
• U/f operation: Assignment of rated currents of motor and Power
Module
• Line quality
• Make sure that the line commutating reactor is connected properly
• Power cable connections
• Power cables for short-circuit or ground fault
• Power cable length
• Line phases
If this doesn't help:
• U/f operation: Increase the acceleration ramp
• Reduce the load
• Replace the power unit
F30002 DC-link voltage overvoltage Increase the ramp-down time (p1121).
Set the rounding times (p1130, p1136).
Activate the DC-link voltage controller (p1240, p1280).
Check the line voltage (p0210).
DC-link voltage undervoltage
Check the line voltage (p0210).
F30004 Inverter overtemperature Check whether the inverter fan is running.
Check whether the ambient temperature is in the permissible range.
Check whether the motor is overloaded.
Reduce the pulse frequency.
F30005 I2t inverter overload Check the rated currents of the motor and Power Module.
Reduce the current limit p0640.
When operating with U/f characteristic: Reduce p1341.
F30011 Line phase failure Check the inverter's input fuses.
Check the motor feeder cables.
F30015 Motor cable phase failure Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
