Bluetooth Communication Fault
The smartphone or tablet with Q2dev 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.
Note:
•
The drive detects this error when you use the Bluetooth LCD keypad and operate the drive with a smartphone or tablet.
•
Do a Fault Reset to clear the fault.
•
Set the stopping method for this fault in
o2-27 [BLE Disconn.Selection@BLE Ctrl]
.

BrakingTransistor Overload Fault
The duty cycle of the braking transistor is high (the
regeneration power or repetition frequency is high).
•
Install a regenerative converter.
•
Increase the deceleration time.
You enabled the protective function for the braking
transistor when you have a regenerative converter.
Set
L8-55 = 0 [DB IGBT Protection = Disable]
.
The braking transistor in the drive is broken.
Replace the drive.
Note:
Do a Fault Reset to clear the fault.

Option Communication Error
The drive did not receive a signal from the
controller.
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.
The option is incorrectly installed to the drive.
Correctly install the option to the drive.
The option is damaged.
If the fault continues and the wiring is correct, replace the option.
Note:
•
The drive detects this error if the Run command or frequency reference is assigned to the option card.
•
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
F6-01 [Comm.Error Selection]
.

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.
