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
Autotuning was not completed in the
specified time.
PG pulses were input when the Inverter
was outputting a frequency.
The torque reference exceeded 100%
and the no-load torque exceeded 70%
during autotuning.
The results of autotuning has exceeded
the setting range for a user parameter so
a temporary setting was made for the
motor core saturation coefficient.
The rated current is set high.
As a result of stationary autotuning 1,
the slip value has fallen to 0.2 Hz or
below.
Table 7.5 Errors during Copy Function
Meaning
Probable causes
o3-01 was set to 1 to write a parameter
when the Digital Operator was write-
protected (o3-02 = 0).
The read data length does not agree.
The write data is incorrect.
An attempted write of a parameter to
EEPROM on the Digital Writer failed.
Protective and Diagnostic Functions
Corrective Actions
Check the motor wiring.
Fix the broken/disconnected 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).
• Check the input data.
• If rotational autotuning is possible,
perform it. If impossible, perform sta-
tionary autotuning 2.
Corrective Actions
Set o3-02 to 1 to enable writing
parameters with the Digital Operator.
Repeat the read.
Check the Digital Operator cable.
Replace the Digital Operator.
A low Inverter voltage has been
detected.
Repeat the read.
Replace the Digital Operator.
