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.

*
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.

The
rated current is set high.
Check
the input data (particularly the
motor
output current and motor rated
current).
