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.
Note:
•
The drive detects this error if it does not correctly receive control data for the
CE
detection time set to
H5-09 [CE Detection Time]
.
•
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
H5-04 [Communication Error Stop Method]
.

CF
Control Fault
Motor parameters are set incorrectly
Correctly set the motor parameters and do Auto-Tuning again.
The torque limit setting is too low.
Adjust
L7-01 to L7-04 [Torque Limit]
.
The load inertia is too large.
•
Adjust
C1-02, C1-04, C1-06, and C1-08 [Deceleration Times]
.
•
Set the frequency reference to the minimum output frequency,
and stop the Run command when the drive stops deceleration.
The drive is trying to ramp to stop a machine that
cannot do ramp to stop or on a machine for which
deceleration is not necessary.
Correctly set
b1-03 [Stopping Method Selection]
.
The motor and drive are connected incorrectly.
Correct wiring errors.
Line-to-line Resistance Tuning is not done.
Do Stationary Auto-Tuning for Line-to-Line Resistance.
The drive received a Run command while the motor
was coasting.
•
Examine the sequence and input the Run command after the
motor fully stops.
•
Set
b3-01 = 1 [Speed Search at Start Selection = Enabled]
.
Note:
•
The drive detects this error if the torque reference is more than the torque limit for 3 seconds or longer while the drive ramps to stop.
•
Do a Fault Reset to clear the fault.

CoF
Current Offset Fault
The drive starts operation while the induced voltage
stays in the motor (during coasting to a stop or after
fast deceleration).
•
Make a sequence that does not restart operation when induced
voltage stays in the motor.
•
Set
b3-01 = 1 [Speed Search at Start Selection = Enabled]
.
•
Use
Speed Search from Fmax or Fref [H1-xx = 61, 62]
to do a
speed search through one of the external terminals.
Note:
When controlling the PM motor, External Speed Search
commands 1 and 2 operate the same.
A drive hardware problem occurred.
•
Do a Fault Reset to clear the fault or de-energize the drive.
•
If the fault stays, replace the drive.
