7.5.4 Compressor current limit protection
If the compressor current exceeds the current limit value for 10 seconds, the compressor frequency will be
limited as below table.
For models except M5OA-36HRDN1-Q.
Cooling mode:
Current frequency(Hz)
COOL_F10
COOL_F9
COOL_F8
COOL_F7
COOL_F6
COOL_F5
If the current frequency is lower than COOL_F4, the frequency will not be limited.
After 10s of the compressor start, if the current>ICOOL,the AC will display the failure for 30 seconds
and stop. The AC will restart 3 minutes later.
Heating mode:
Current frequency(Hz)
HEAT_F12
HEAT_F11
HEAT_F10
HEAT_F9
HEAT_F8
HEAT_F7
HEAT_F6
HEAT_F5
If the current frequency is lower than HEAT_F4, the frequency will not be limited.
After 10s of the compressor start, if the current>IHEAT,the AC will display the failure for 30 seconds
and stop. The AC will restart 3 minutes later.

Frequency limit
Decrease the frequecny to COOL_F4 and
run at COOL_F4 for 3 minutes.
After that,the frequency will be adjusted
according to the capacity demand and rise
to the upper level every 3 minutes
(When the
capacity demand).
Frequency limit
Decrease the frequecny to HEAT_F4 and
run at HEAT_F4 for 3 minutes.
After that,the frequency will be adjusted
according to the capacity demand and rise
to the upper level every 3 minutes
(When the frequency>Heat_F4 via capacity
demand).
