YASKAWA SIEPYEULA5001C LA500 Technical Manual 175
Code Name Causes Possible Solutions
CPF38 Control Circuit Error
A drive hardware problem occurred. • 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.
Note:
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for these faults.
Code Name Causes Possible Solutions
CPF06 Control Circuit Error (EEPROM
memory Data Error) The drive power supply was de-energized while a
communication option entered a parameter Write
command. Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire
Initialization, 3-Wire Initialization] and initialize the drive.
An EEPROM peripheral circuit error occurred. • Re-energize the drive.
• If the fault stays, replace the control board or the drive. For
information about how to replace the control board, contact
Yaskawa or your nearest sales representative.
Note:
•
The drive detects this error if there is an error in the data written to the drive EEPROM.
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for these faults.
Code Name Causes Possible Solutions
CPF25 Terminal Board not Connected The terminal board is not correctly connected to the
drive. 1. De-energize the drive.
2. Correctly connect the terminal board to the drive.
3. Re-energize the drive.
Note:
Do a Fault Reset to clear the fault.
Code Name Causes Possible Solutions
dCE1 Communication Error1
A drive hardware problem occurred temporarily due
to noise. • Remove the cause of the noise.
• If the fault stays, replace the control board or the drive.
Note:
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for these faults.
Code Name Causes Possible Solutions
dCE2 Communication Error2 A drive hardware problem occurred temporarily due
to noise.
•
Remove the cause of the noise.
•
If the fault stays, replace the control board or the drive.
Note:
• Do a Fault Reset to clear the fault.
•
Fault trace is not available for these faults.
Code Name Causes Possible Solutions
dv7 Polarity Judge Timeout
There is a disconnection in the motor coil winding. Measure the motor line-to-line resistance and replace the motor if
a coil is disconnected.
The screws on the drive output terminals are loose. Tighten the terminal screws to the correct tightening torque.
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.
Code Name Causes Possible Solutions
EF1 External Fault (Terminal S1)
MFDI terminal S1 caused an external fault through
an external device. 1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input in the MFDI.
The wiring is incorrect. Correctly connect the signal line to MFDI terminal S1.
External Fault [H1-01 = 20 to 2B] is set to MFDI
terminal S1, but the terminal is not in use.
Correctly set the MFDI.
Note:
Do a Fault Reset to clear the fault.
Code Name Causes Possible Solutions
EF2 External Fault (Terminal S2) MFDI terminal S2 caused an external fault through
an external device. 1. Find the device that caused the external fault and remove the
cause.
2. Clear the external fault input in the MFDI.
The wiring is incorrect. Correctly connect the signal line to MFDI terminal S2.
External Fault [H1-02 = 20 to 2B] is set to MFDI
terminal S2, but the terminal is not in use.
Correctly set the MFDI.
Note:
Do a Fault Reset to clear the fault.
