6.5 Copy Function Errors
The table below lists the messages and errors that may appear when using the Copy function.
When executing the tasks offered by the Copy function, the keypad will indicate the task being performed. When an
error occurs, a code appears on the keypad to indicate the error. Note that errors related to the Copy function do
not trigger the fault relay. To clear an error, simply press any key on the keypad and the error display will disappear.
NOTE:
1. Whenever using the copy function, the VFD should be fully stopped.
2. The VFD will not accept a Run command while the Copy function is being executed.
3. Parameters can only be saved to a VFD when the model, control method, and firmware version match.
Table 6-7: Copy Function Error Displays
Display
Description
Corrective Action
CPEr
Control Method Mismatch.
Control method of the
parameters to be loaded onto the VFD and the control
method set to the VFD do not match.
• Verify the control method for the
parameters to be loaded onto the VFD
and the control method on the VFD to
which those parameters will be written.
• Set the same control method using
parameter A01-02 and retry.
CPyE
Error Writing Data.
Failed writing parameters.
Attempt to write parameters again.
CSEr
Copy Unit Error.
Hardware fault.
Replace the keypad or the USB Copy Unit.
iFEr
Communication Error.
• A communication error occurred between the VFD and
the keypad or the USB copy unit.
• A non-compatible cable is being used to connect the
USB Copy Unit and the VFD.
• Check the cable connection.
• Use the cable originally packaged with
the USB Copy Unit.
ndAT
Model, Voltage Class, Capacity Mismatch.
• The VFD from which the parameters were copied and
the VFD to which the parameters will be written have
different electrical specifications, capacities, are set to
different control methods, or are different models.
• The device being used to write the parameters is blank
and does not have any parameters saved on it.
• Make sure model numbers and
specifications are the same for both
VFDs.
• Make sure all connections are correct,
and copy the parameter settings onto the
USB Copy Unit or the keypad.
rdEr
Error Reading Data.
Failed while attempting to read
parameter settings from the VFD.
Press and hold the READ key on the USB
Copy Unit for at least one second to have
the unit read parameters from the VFD.
vAEr
Voltage Class, Capacity Mismatch.
The VFD from
which the parameters were copied and the VFD on which
the Verify mode is being performed have different
electrical specifications or are a different capacity.
Make sure electrical specifications and
capacities are the same for both VFDs.
vFyE
Parameter settings in the VFD and those saved to the
copy function are not the same.
Indicates that
parameter settings that have been Read and loaded onto
the Copy Unit or keypad are different.
To synchronize parameters, either write the
parameters saved on the USB Copy Unit or
keypad onto the VFD, or Read the
parameter settings on the VFD onto the
USB Copy Unit.
