Causes
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] is set.
Note:
You cannot do Inertia Tuning if the drive cannot
rotate the motor in reverse.

Causes
The keypad setting and drive setting for A1-02
[Control Method Selection] do not align.
Parameter restore did not end correctly.
The keypad is broken.
You tried to restore parameters to a drive model that
is different than the drive model 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.
The parameters are not stored in the keypad.
The password set in the backup operation with qx-xx
[DriveWorksEZ Parameters] and rx-xx
[DriveWorksEZ Connections] is incorrect.
You tried to back up when o3-02 = 0 [Copy Allowed
Selection = Disabled].
• 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.

State
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.

backed up to the keypad.
The parameter settings stored in the keypad
and the parameter settings in the drive align
or are being compared.
