K 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.
Motor Speed
Motor speed error
(detected only for
rotational autotuning)
The torque reference was too high
(100%) during acceleration (for open
loop vector control only).
•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).
I-det Circuit
Current detection
error
The current flow exceeded the motor
rated current.
Check the current detection circuit,
motor wiring, current detector, and
installation methods.
The detected current sign was the oppo-
site of what it should be.
There is a phase fault for U, V, or W.
Leak Inductance
Leakage inductance
error
Autotuning was not completed in the
specified time.
Check motor wiring.
V/f Over Setting
V/f settings exces-
sive
*
The torque reference exceeded 100%
and the no-load torque exceeded 70%
during autotuning.
•Check and correct the settings.
• Disconnect the load from the motor.
Saturation
Motor core satura-
tion error (detected
only for rotational
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.
•Check the input data.
•Check motor wiring.
•If the motor is connected to the
machine, disconnect it.
Rated FLA Alm
Rated current setting
alarm
*
The rated current is set high.
Check the input data (particularly the
motor output current and motor rated
current).
