1: The motor parameters are not set
according to the nameplate.
2: The motor auto-tuning times out.
1: Set the motor
parametersaccording to the
nameplateproperly.
2: Check the cable connecting
between the Frequency inverter
and themotor.
Off load

Er. LL
1、The frequency inverter running
currentis lower than the setting value.
1、Confirm whether the load is
off
2、Check that the load is
disconnected or the parameter
setting is correct

Er.Ud1
1: The signal of user-defined fault 1 is
input via DI.
2:The signal of user-defined fault 1 is
input via virtual I/O.
1: Reset the operation.
2: Reset the operation
User-defined
fault 2
38
Er.Ud2
1: The signal of user-defined fault 2 is
input via DI.
2:The signal of user-defined fault 2 is
input via virtual I/O.
1: Reset the operation.
2: Reset the operation
The fault code is used for the communication read fault type: when the communication reads the
registers r25.00, r26.00, r26.08, r26.16, the register contents of the reply are fault coded.
6.2 Warning type
The warning is used to remind and inform the user of the current state of the inverter. When the warning
occurs, the keypad will display a warning message, and the warning will automatically reset when the
warning is cleared. Some warnings require the user to check the cause before running the drive, and
some do not care. Warning As an instant reminder, the drive does not store the corresponding
information.
