Errors when Using the Digital Operator Copy Function

The errors that can occur when using the copy function from the Digital Operator are given in the following
table. An error code will be displayed on the Digital Operator. If a Digital Operator key is pressed when an
error code is being displayed, the display will be cleared and 03-01 will be displayed. The error contact output
and alarm output will not function.
Table 7.4 Errors During Autotuning (Continued)
Probable causes
The torque reference was too high
(100%) during acceleration (for open
loop vector control only).
The current flow exceeded the motor
rated current.
The detected current sign was the oppo-
site of what it should be.
There is a phase fault for U, V, or W.
Autotuning was not completed in the
specified time.
The torque reference exceeded 100%
and the no-load torque exceeded 70%
during autotuning.
Autotuning for the motor core saturation
value could not be completed in the
specified time.
The results of autotuning has exceeded
the setting range for a parameter so a
temporary setting was made for the
motor core saturation coefficient.
The rated current is set high.
Protective and Diagnostic Functions
Corrective Actions
• If the motor is connected to the
machine, disconnect it.
• Increase C1-01 (Acceleration Time 1).
• Check the input data (particularly the
number of PG pulses and the number
of motor poles).
Check the current detection circuit,
motor wiring, current detector, and
installation methods.
Check motor wiring.
• Check and correct the settings.
• Disconnect the load from the motor.
• Check the input data.
• Check motor wiring.
• If the motor is connected to the
machine, disconnect it.
Check the input data (particularly the
motor output current and motor rated
current).
