Errors During Autotuning; Errors When Using The Digital Operator Copy Function - YASKAWA Varispeed E7 Instruction Manual And Parameter Description

Errors During Autotuning

The errors that can occur during autotuning are given in the following table. If an error is detected, the motor
will coast to a stop and an error code will be displayed on the Digital Operator. The error contact output and
alarm output will not function.
Display
* Displayed after autotuning has been completed.

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 o3-01 will be displayed. The error contact output
and alarm output will not be operated.

Table 7.4 Errors During Autotuning
Meaning
There is an error in the data input for
autotuning.
There is an error in the relationship
between the motor output and the motor
rated current.
Motor data error
The is an error between the no-load cur-
rent setting and the input motor rated
current (when autotuning for only line-
to-line resistance is performed for vector
control).
A minor fault occurred during autotun-

Autotuning was not completed in the
Line-to-line resis- specified time.
tance error The results of autotuning has exceeded
the setting range for a user constant.
Rated current setting
The rated current is set too high.

Table 7.5 Errors during Copy Function
Meaning
o3-01 was set to 1 to read constants
Digital Operator
when the Digital Operator was write-
write-protected
protected (o3-02 = 0).
The read data length does not agree.
Illegal read data
The read data are incorrect.
An attempted write of a constant to the
Illegal write status EEPROM of the Digital Operator
failed.

Corrective Actions
• Check the input data.
• Check the capacity of the Inverter and
motor.
• Check the motor rated current and no-
load current.
• Check the input data.
• Check wiring and the machine.
• Check the load.
• Check the input data.
• Check motor wiring.
• If the motor is connected to the
machine, disconnect it.
Check the input data (particularly the
motor rated current).
Corrective Actions
Set o3-02 to 1 to enable writing con-
stants into the Digital Operators mem-
ory.
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.
