Causes
Possible Solutions
CP1
Comparator 1 Limit Fault
The monitor value set in
H2-20 [Comparator 1
Monitor Selection]
was in the range of
H2-21
[Comparator 1 Lower Limit]
and
H2-22
[Comparator 1 Upper Limit]
.
Examine the monitor value and remove the cause of the fault.
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.
CPF00 to

CPF26 to
CPF39
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.
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.
dEv
Speed Deviation
The load is too heavy.
Decrease the load.
dv1
Z Pulse Fault
The encoder option card or the encoder on the motor
side is damaged.
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.
dv2
Z Pulse Noise Fault Detection
Noise interference along the encoder cable.
Isolate the encoder cable from the drive output line or a different
source of electrical interference.
dv3
Inversion Detection
E5-11 [Encoder Z-Pulse Offset]
is set incorrectly.
Correctly set the value for Δθ to
E5-11
as specified by the values on
the motor nameplate.
dv4
Inversion Prevention Detection
An external force on the load side rotated the motor.
•
Make sure that the motor is rotating in the correct direction.
•
Find and repair problems on the load side that cause the motor to
rotate from the load side.
•
Disable detection of this fault for applications that rotate the
motor from the load side in the opposite direction of the speed
reference. The drive will not detect this fault if
F1-19 = 0
[Deviation 4 Detection Selection = Disabled]
.
E5-11 [Encoder Z-Pulse Offset]
is set incorrectly.
Correctly set the value for Δθ to
E5-11
as specified by the values on
the motor nameplate.
There is a new encoder or the motor rotation direction
changed.
Do Z Pulse Offset Tuning.
Noise interference along the encoder cable.
Correctly ground the shielded wire of the encoder cable.
The encoder cable is disconnected or wired
incorrectly.
Examine for wiring errors or disconnected wires in the encoder
cable, and repair problems.
The drive incorrectly detected the motor magnetic
pole position.
If the value for
U6-57 [PolePolarityDeterVal]
is lower than 819,
increase the value set in
n8-84 [Polarity Detection Current]
.
Consult the motor manufacturer for information about maximum
setting values.
The setting of
n8-84 [Polarity Detection Current]
is
too low.
Increase the
n8-84
setting from the default. Consult the motor
manufacturer for information about maximum setting values.
Pole Position Detection failed.
If you are using an IPM motor, do High Frequency Injection Auto-
Tuning.
The PG option card or the encoder on the motor side
is damaged.
Repair the wiring and re-energize the drive, then replace the PG
option card or the PG if the problem continues.
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.
dWF1
EEPROM Memory DWEZ Data
Error
There is an error in the EEPROM peripheral circuit.
•
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.
dWFL
DriveWorksEZ Fault
There was a fault in the DriveWorksEZ program.
Examine the DriveWorksEZ program and remove the cause of the
fault. This is not a drive fault.
E5
MECHATROLINK Watchdog Timer
Err
The drive detected a watchdog circuit exception while
it received data from the controller.
Examine the MECHATROLINK cable connection. If this error
occurs frequently, examine the wiring and decrease the effects of
electrical interference as specified by these manuals:
•
MECHATROLINK-II Installation Guide (MECHATROLINK
Members Association, manual number MMATDEP011)
•
MECHATROLINK-III Installation Manual (MECHATROLINK
Members Association, publication number MMATDEP018)
