OH: Frequency converter over temperature
Possible reason Solution
Frequency converter (heat sink) tem-
perature is higher than max. allowable
temperature 85 °C
● Reduce ambient temperature, improve ventilation and
heat dissipation; clear dust, cotton wadding in air ducts;
check fan and its power supply connection (if available)
● Reduce load if necessary
● Reduce carrier frequency (b0.21)
Temperature detection circuit error Contact with service
CPUC: I/O board trap error
Possible reason Solution
Fatal error with CPU on I/O board
● Check the wiring of control circuit, main circuit and
grounding to find out the source of interference
● If it happens again, contact with service
CPUE: Operating panel trap error
Possible reason Solution
Fatal error with CPU on operating panel
● Check the wiring of control circuit, main circuit and
grounding to find out the source of interference
● If it happens again, contact with service
CE3-: SPI problem between operating panel board and I/O board
Possible reason Solution
Problem with operating panel
● Check the wiring of control circuit, main circuit and
grounding to find out the source of interference
● If it happens again, replace the operating panel or contact
with service
CE4-: Internal problem on operating panel
Possible reason Solution
Problem with operating panel
● Check the wiring of control circuit, main circuit and
grounding to find out the source of interference
● If it happens again, replace the operating panel or contact
with service
