3-2-4 Error Displays for the Parameter Copy and Verify
Function
This section describes the errors that may occur when reading, copying, or verifying parameters, and
the remedies for those errors. The display will flash when any of these errors occurs.
Display Probable
cause
Name Remedy
Protect error A read attempt was made with the
Parameter Read Prohibit Selection
(n77) set to 0 (reading prohibited).
Check again whether data must be
read, and if required, change the
setting for n77 to 1 (reading possible),
and then read the data again.
Read error The parameters were not read
correctly or a low voltage was
detected in the main circuit when the
data was being read.
Check that the main circuit voltage is
normal, and then read the data again.
Checksum
error
A checksum error occurred for the
parameters saved in the Digital
Operator.
Read the parameters to the Digital
Operator again.
No-data Error There are no parameters saved in the
Digital Operator.
Read the parameters to the Digital
Operator.
Copy target
error
An attempt was made to copy or verify
between Inverters with different
voltage classes or control modes.
Check the voltage classes and control
modes. (If either is different from that
of the other Inverter, copying and
verifying are not possible.)
If an Inverter has a different control
mode, change the control mode of the
Inverter to be copied to or verified,
and then copy or verify the
parameters again.
Voltage error
while copying
A low voltage in the main circuit was
detected while data was being copied.
Check that the main voltage is
normal, and then copy the data again.
Capacity error An attempt was made to verify
parameters between Inverters with
different capacities.
To continue verification, press the
Enter Key. To cancel verification,
press the STOP/RESET Key.
Communica-
tions error
A communications error occurred
between the Inverter and the Digital
Operator.
Check the connection between the
Inverter and the Digital Operator.
Make sure the connection is correct,
and then repeat the operation.
