7.4 Fault
YASKAWA SIEPC71061737B GA800 Drive Technical Reference 319
Code Name Causes Possible Solutions
CP2 Comparator 2 Limit Fault
The monitor value set in H2-26 [Comparator 2
Monitor Selection] was outside the range of H2-27
[Comparator 2 Lower Limit] and H2-28
[Comparator 2 Upper Limit] .
Examine the monitor value and remove the cause of the fault.
Note:
• The drive detects this error when the terminal is set to H2-01 to H2-03 = 67 [MFDO Function Selection = Comparator2] .
• Do a Fault Reset to clear the fault.
• Set the stopping method for this fault in H2-35 [Comparator2 Protection Selection] .

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 EEPROM Memory Data Error
The drive power supply was de-energized while a
communication option card 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 replacing 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 EEPROM of the drive.
•
Do a Fault Reset to clear the fault.
•
Fault trace is not available for this fault.
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
dEv Speed Deviation The load is too heavy. Decrease the load.
Acceleration and deceleration times are set too short. Increase the values set in C1-01 to C1-08 [Acceleration/
Deceleration Time] .
The dEv detection level settings are incorrect. Adjust F1-10 [Speed Deviation Detection Level] and F1-11 [Speed
Deviation Detect DelayTime] .
The load is locked up. Examine the machine.
The holding brake is stopping the motor. Release the holding brake.
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 Causes Possible Solutions
dv1 Z Pulse Fault
The encoder option card or the encoder on the motor
side is damaged.
The encoder cable is disconnected or wired
incorrectly.
1. Repair wiring errors and connect disconnected wires. Correctly
ground the shielded wire of the encoder cable.
2. Re-energize the drive
3. 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:
• The drive detects this error if it does not detect a Z pulse during one motor rotation.
• Do a Fault Reset to clear the fault.
