YASKAWA CR700

13 Troubleshooting
74 YASKAWA TOEPC71061723A YASKAWA AC Drive CR700 Quick Start Guide
Code Name Causes Possible Solutions
Er-12 Current Detection Error
There is a phase loss in the drive input power. (U/
T1, V/T2, W/T3)
Examine and repair motor wiring.
Er-13 Leakage Inductance Alarm
The motor rated current value is incorrect. Correctly set the rated current indicated on the motor nameplate
and perform Auto-Tuning again.
Er-14 Motor Speed Error 2
The motor speed was more than two times the
amplitude of speed reference during Inertia Tuning.
Decrease the value set in C5-01 [ASR Proportional Gain 1].
Er-15 Torque Saturation Error
During Inertia Tuning, the output torque was more
than the value set in L7-01 to L7-04 [Torque Limit].
• 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.
Er-16 Inertia ID Error
The inertia found by the drive was too small or too
large during Inertia Tuning (10% or less, or
50000% or more).
• 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.
Er-17 Reverse Prohibited Error
b1-04 = 1 [Reverse Operation Selection = Reverse
Disabled]
Note:
You cannot do Inertia Tuning if the drive cannot
rotate the motor in reverse.
1. Enable reverse in the target machine.
2. Set b1-04 = 0 [Reverse Enabled].
3. Do Inertia Tuning again.
◆ 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 Name Display Status
Drive and Keypad mismatch.
Should the parameters be
restored?
Detection of inconsistency between the
drive and keypad
Normally displayed 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.
Restore Restore from keypad Restoring parameters Flashing The parameters stored in the keypad have
been restored to the drive.
End Backup/restore/verify operation ended
normally
Normally displayed The parameter backup, restore, or verify
operation ended normally.
Backup Backup from Drive Backing up parameters Flashing The parameters stored in the drive are
being backed up to the keypad.
Verify Keypad & Drive Verifying parameters Flashing The parameter settings stored in the
keypad and the parameter settings in the
drive match or are being compared.
■ 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.
Code Name Causes Possible Solutions
CPEr Control Mode Mismatch
The keypad setting and drive setting for A1-02
[Control Method Selection] do not agree.
1. Set A1-02 on the drive to the same value that is on the
keypad.
2. Restore the parameters.
CPyE Error Writing Data
Parameter restore did not end correctly. Restore the parameters.
CSEr Control Mode Mismatch
The keypad is broken. Replace the keypad.
dFPS Drive Model Mismatch
You tried to restore parameters to a different drive
model than the one that you backed up.
1. Examine the drive model that you used to back up the
parameters.
2. Restore the parameters.
iFEr Keypad Communication Error
There was a communications error between the
keypad and the drive.
Examine the connector or cable connection.
ndAT Error Received Data
The parameter settings for model and specifications
(power supply voltage and capacity) are different
between the keypad and the drive.
1. Make sure that drive model and the value set in o2-04 [Drive
Model (KVA) Selection] agree.
2. Restore the parameters.
