Backup Function Operating Mode Display and Errors

■
Operating Mode Display
When you use the LCD keypad to do the backup function, the keypad shows the running operation on the LCD
display. These indicators do not show that an error has occurred.
Keypad Display
Drive and Keypad mismatch.

Backup Function Runtime Errors
When an error occurs, the keypad shows a code to identify the error.
The table in this section show the error codes. If there are errors, refer to these tables:
Note:
Push any key on the keypad to clear an error.

Causes
There is a phase loss in the drive input power. (U/
T1, V/T2, W/T3)
The motor rated current value is incorrect.
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
During Inertia Tuning, the output torque was more
than the value set in L7-01 to L7-04 [Torque Limit].
The inertia found by the drive was too small or too
large during Inertia Tuning (10% or less, or
50000% or more).
b1-04 = 1 [Reverse Operation Selection = Reverse
Disabled]
Note:
You cannot do Inertia Tuning if the drive cannot
rotate the motor in reverse.

Backing up parameters
Verifying parameters
Causes
The keypad setting and drive setting for A1-02
[Control Method Selection] do not agree.
Parameter restore did not end correctly.
The keypad is broken.
You tried to restore parameters to a different drive
model than the one that you backed up.
There was a communications error between the
keypad and the drive.
The parameter settings for model and specifications
(power supply voltage and capacity) are different
between the keypad and the drive.
Examine and repair motor wiring.
Correctly set the rated current indicated on the motor nameplate
and perform Auto-Tuning again.
Decrease the value set in C5-01 [ASR Proportional Gain 1].
• Increase the value set in L7-01 to L7-04 [Torque Limit] as
much as possible.
• Decrease the values set for the frequency and amplitude of the
test signals used when doing inertia tuning. First, decrease the
test signal amplitude, and then do Inertia Tuning. If the error
continues, decrease the test signal frequency and do Inertia
Tuning again.
• Decrease the values set for the frequency and amplitude of the
test signals used when doing inertia tuning. First, decrease the
test signal amplitude, and then do Inertia Tuning. If the error
continues, decrease the test signal frequency and do Inertia
Tuning again
• Correctly set the motor inertia as specified by the motor, and
do Inertia Tuning again.
1. Enable reverse in the target machine.
2. Set b1-04 = 0 [Reverse Enabled].
3. Do Inertia Tuning again.

1. Examine the drive model that you used to back up the
parameters.
2. Restore the parameters.
Examine the connector or cable connection.
1. Make sure that drive model and the value set in o2-04 [Drive
Model (KVA) Selection] agree.
2. Restore the parameters.

Status
The drive detected the connection of a
keypad from a different drive. Select [Yes]
to copy parameters backed up in the
keypad to the connected drive.
The parameters stored in the keypad have
been restored to the drive.
The parameter backup, restore, or verify
operation ended normally.
The parameters stored in the drive are
being backed up to the keypad.
The parameter settings stored in the
keypad and the parameter settings in the
drive match or are being compared.
