5
Communication error
10 (CE10)
RS-485 Modbus transmission time-out
Action condition
When the communication time exceeds the detection time of Pr.09-
03
communication time-out
Warning setting parameter
Reset method
“Warning” occurs when Pr.09-
02=0 and the motor drive keeps running. The drive
resets automatically when receiving the next communication packet.
The upper unit does not transmit
the communication command
within Pr. 09-03 setting time
Check if the upper unit transmits the communication command within
time for Pr.09-03.
Malfunction caused by
interference
Verify the wiring and grounding of the communication circuit. It is recommended
to separate the communication circuit from the main circuit, or wire in 90 degree
for effective anti-interference performance.
Different communication setting
Check if the setting for Pr.09-04 is the same as the setting for the upper unit.
Disconnection or bad connection
Check the cable and replace it if necessary.
Keypad
communication time
out (CK10)
Keypad communication data, transmission time-out
(Keypad auto-detect this error and display it.)
Action condition
When the communication time exceeds the detection time of Pr.09-03
Warning setting parameter
Remove the keypad and then reconnect it to the motor drive.
Incorrect communication
Keypad and the motor drive don’
t communicate properly. It is recommended to
remove the keypad and then reconnect it to the motor drive.
Malfunction caused by
interference
Verify the wiring and grounding of the communication circuit. It is
recommended
to separate the communication circuit from the main circuit, or wire in 90 degree
for effective anti-interference performance.
Different communication setting
Check if the Baud rate = 19200 bps. Format = RTU8, N, 2.
Disconnection or bad connection
Check the cable and replace it if necessary.
