Possible cause
Problem in application software.
Software function requires newer
control board.
Option board or control unit changed.
Same type of board or same power
rating of drive. The parameters are
available in the drive.
Option board or drive added.
Drive of same power rating or same
type of board added. The parameters
are available in the drive.
Option board removed.
Drive removed.
Unknown option board or drive.
IGBT Inverter Bridge overtemperature
protection has detected too high a
short term overload current
Internal brake resistor
overtemperature protection has
detected too heavy braking
Note the exceptional Fault data
record. See 7.3.4.3. Additional codes:

Check loading.
Check motor size.
Make an identification run.
Set the deceleration time longer.
Use external brake resistor.
Check encoder channel connections.
Check the encoder board.
Check the encoder frequency in the
open loop.
