F08700 Communications error A CAN communications error has occurred. Check the following:
• Bus cable
• Baud rate (p8622)
• Bit timing (p8623)
• Master
Start the CAN controller manually with p8608 = 1 after the cause of the fault
F13100 Know-how protection: Copy
protection error
The know-how protection and the copy protection for the memory card are
active. An error occurred during checking of the memory card.
• Insert a suitable memory card and switch the converter 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's 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 Converter overtemperature Check whether the converter 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 converter overload Check the rated currents of the motor and Power Module.
Reduce current limit p0640.
When operating with U/f characteristic: Reduce p1341.
