Error code
E60
Remote controller:
E60-1, 2 *1
7-segment display:
*1 E60-1 : CM1, E60-2 : CM2 *2 E60-1 : 1 time flash E60-2 : 2 time flash
1. Applicable model
Outdoor unit
2. Error detection method
Detection of the compressor
rotor position.
3. Condition of error displayed
If it fails to detect the rotor
position of compressor, after
changinging over to the operation
of compressor rotor position
detection, the compressor stops.
When it is restart automatically
after 3 minutes delay, this
anomaly occurs 4 times within 15
minute after the initial detection
4. Presumable cause
• Compressor anomaly
• Inverter PCB anomaly
• Anomaly of power supply
Note:
If the error does not recur, connect the Mente PC and continue to collect data.

NO
the unit with 2
compressors?
YES
When
interchanging the
cables between inverter and
compressor, is the compressor
failed to startup
switched?

–
Countermeasure
Check and save the data of
operating conditions
Correct it
NO
Check it as much as
possible under the
operating conditions for
30 minutes before error
occurred
YES
Correct it according to the
troubleshooting procedure
of E59
Correct it according to the
NO
troubleshooting procedure
of E42
YES
Replace compressor
Check the insulation
resistance and coil
resistance of compressor.
If necessary, replace
compressor
NO
Replace inverter PCB
NO
Replace compressor
