When the current detected by current sensor exceeds 105% of the rated current continuously
for 30 seconds or for 3 minutes in total during a 10-minute period, overcurrent is detected.
Protection of Power
Integrated Module (PIM)
Power Integrated module (PIM) has four protection functions for self-protection.
(1) Some of the output terminals between “U” and “V”, “V” and “W”, “W” and “U” have a short-
circuit.
(2) Running current reaches the maximum rated current.
(3) Abnormal temperature is measured by internal thermistor.
(4) Control voltage decreases abnormally.
Overload Control
Overload control at a current greater than (Rated Current x 105%).
Overload control release at a current smaller than (Rated Current x 88%).
CaseTemperature Increase The unit is stopped when the PIM Tc temperature is higher than 212°F(100
).
Earth Detection The unit is stopped when the compressor is earthing.
