Control Circuit Error
CPF02, CPF03,
CPF06, CPF08,
CPF11 to
CPF14, CPF16
to CPF24,
CPF38
Note:
• Do a Fault Reset to clear the fault.
• Fault trace is not available for these faults.
Code Name
CPF06 EEPROM Memory Data Error
Note:
• The drive detects this error if there is an error in the data written to the EEPROM of the drive.
• Do a Fault Reset to clear the fault.
• Fault trace is not available for this fault.
Code Name
CPF25 Terminal Board not Connected
Note:
Do a Fault Reset to clear the fault.
Code Name
dCE1 Communication Error1
Note:
• Do a Fault Reset to clear the fault.
• Fault trace is not available for these faults.
Code Name
dCE2 Communication Error2
Note:
• Do a Fault Reset to clear the fault.
• Fault trace is not available for these faults.
Code Name
dEv Speed Deviation
Note:
• The drive detects this error if the difference between the detected speed and the speed reference is more than the setting of F1-10 for longer than F1-11.
• Do a Fault Reset to clear the fault.
• If the drive detects this error, the drive will operate the motor as specified by the stopping method set in F1-04 [Speed Deviation Detection Select].
Code Name
dv7 Polarity Judge Timeout
Note:
• The drive detects this error if it cannot detect polarity in a pre-set length of time.
• Do a Fault Reset to clear the fault.

Causes
A drive hardware problem occurred.
Causes
The drive power supply was de-energized while a
communication option card entered a parameter
Write command.
An EEPROM peripheral circuit error occurred.
Causes
The terminal board is not correctly connected to the
drive.
Causes
A drive hardware problem occurred temporarily due
to noise.
Causes
A drive hardware problem occurred temporarily due
to noise.
Causes
The load is too heavy.
Acceleration and deceleration times are set too
short.
The dEv detection level settings are incorrect.
The load is locked up.
The holding brake is stopping the motor.
Causes
There is a disconnection in the motor coil winding.
The screws on the drive output terminals are loose.
Possible Solutions
• Re-energize the drive.
• If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact
Yaskawa or your nearest sales representative.
Possible Solutions
Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire
Initialization, 3-Wire Initialization] and initialize the drive.
• Re-energize the drive.
• If the fault stays, replace the control board or the drive. For
information about replacing the control board, contact
Yaskawa or your nearest sales representative.
Possible Solutions
1. De-energize the drive.
2. Correctly connect the terminal board to the drive.
3. Re-energize the drive.
Possible Solutions
• Remove the cause of the noise.
• If the fault stays, replace the control board or the drive.
Possible Solutions
• Remove the cause of the noise.
• If the fault stays, replace the control board or the drive.
Possible Solutions
Decrease the load.
Increase the values set in C1-01 to C1-08 [Acceleration/
Deceleration Time].
Adjust F1-10 [Speed Deviation Detection Level] and F1-11
[Speed Deviation Detect DelayTime].
Examine the machine.
Release the holding brake.
Possible Solutions
Measure the motor line-to-line resistance and replace the motor if
a coil is disconnected.
Tighten the terminal screws to the correct tightening torque.
