Causes
Possible Solutions
bAT
Keypad Battery Low Voltage
The keypad battery voltage is low.
Replace the keypad battery.
bCE
Bluetooth Communication Fault
The smartphone or tablet with DriveWizard Mobile
installed is too far from the keypad.
Use the smartphone or tablet 10 m (32.8 ft) or nearer to the
keypad.
Note:
bCE
can occur when the smartphone or tablet is 10 m (32.8 ft)
or nearer to the keypad depending on the specifications of the
smartphone or tablet.
Radio waves from a different device are causing
interference with communications between the
smartphone or tablet and keypad.
Make sure that no device around the keypad uses the same radio
bandwidth (2400 MHz to 2480 MHz), and prevent radio
interference.
boL
BrakingTransistor Overload Fault
The duty cycle of the braking transistor is high (the
regeneration power or repetition frequency is high).
•
Install a braking unit (CDBR-series).
•
Install a regenerative converter.
•
Increase the deceleration time.
bUS
Option Communication Error
The drive did not receive a signal from the
controller.
Correct wiring errors.
CE
Modbus Communication Error
The communications cable wiring is incorrect.
Correct wiring errors.
There is a short circuit in the communications cable
or the communications cable is not connected.
•
Repair short circuits and connect cables.
•
Replace the defective communications cable.
Electrical interference caused a communication data
error.
•
Examine the control circuit lines, main circuit lines, and
ground wiring, and decrease the effects of electrical
interference.
•
Make sure that a magnetic contactor is not the source of the
electrical interference, then use a Surge Protective Device if
necessary.
•
Use only the recommended cables or other shielded line.
Ground the shield on the controller side or the drive input
power side.
•
Separate the communication wiring from drive power lines,
and install a noise filter to the input side of the power supply
for communication.
•
Decrease the effects of electrical interference from the
controller.
CF
Control Fault
Motor parameters are set improperly.
Correctly set the motor parameters and do Auto-Tuning again.
CoF
Current Offset Fault
Drive starts operation while the induced voltage
remains in the motor (during coasting to a stop or
after rapid deceleration).
Specify a sequence in which operation is not restarted when
induced voltage remains in the motor.
A drive hardware problem occurred.
Replace the drive.
CP1
Comparator 1 Limit Fault
The monitor value set in
H2-20 [Comparator 1
Monitor Selection]
was within the range of
H2-21
[Comparator 1 Lower Limit]
and
H2-22
[Comparator 1 Upper Limit]
.
Examine the monitor value setting 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 setting and remove the cause of the
fault.
CPF00 to
CPF03, CPF07
to CPF08,
CPF11 to
CPF14, CPF16
to CPF24, and
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
EEPROM Memory Data Error
The drive power supply was switched off while the
parameter Write command was entered from a
communications option card.
Set
A1-03 = 2220 [Initialize Parameters = 2-Wire initialization]
and initialize the drive.
An EEPROM peripheral circuit error occurred.
•
Re-energize the drive and check if the fault still remains.
•
If the fault stays, replace the control board or the drive. For
instructions on replacing the control board, contact Yaskawa or
your nearest sales representative.
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.
dEv
Speed Deviation
The load is too heavy.
Decrease the load.
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)
