Remedy
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).
Insert a valid memory card.
Check the following:
● Motor data, if required, carry out commissioning
● Motor connection method (Υ / Δ)
● V/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:
● V/f operation: Increase the acceleration ramp
● Reduce the load
● Replace the power unit
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).
Check the line phases.
Check the line voltage (p0210).
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.
Check the rated currents of the motor and Power Module.
Reduce the current limit p0640.
When operating with V/f characteristic: Reduce p1341.
Check the inverter's input fuses.
Check the motor feeder cables.
Check the motor cables.
Increase the ramp-up or ramp-down time (p1120).
● Check the power cable connections.
● Check the motor.
● Check the current transformer.
● Check the cables and contacts of the brake connection (a wire might
be broken).
