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 7.5 Errors During Autotuning (Continued)
Probable causes
The results of autotuning has exceeded
the setting range for a user constant 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.

Meaning Probable causes
o3-01 was set to 1 to write a constant
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 constant to
EEPROM on the Digital Writer failed.
Protective and Diagnostic Functions
Corrective Actions
• 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, per-
form it. If impossible, perform stationary
autotuning 2.
Corrective Actions
Set o3-02 to 1 to enable writing con-
stants 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.
