08-37=0: Start at Operation
Fan starts while inverter is running.
If the inverter stops over the delay time of fan off (08-38), fan is off.
08-37=1: Permanent Start
When the inverter is at power on, fan will start permanently.
08-37=2: Start at High Temperature
When the temperature of heatsink is higher than that of internal setting, fan immediately starts.
If the temperature is lower than internal setting value or the delay time of fan off (08-38) is due, fan will be
off.
Note: Function of fans on is disabled for the models of 60HP or the above (200V) and 100HP or the above
(400V) in IP20 series.

Protection of motor overheating is enabled via the sensor of motor fan with the temperature impedance
chacteristics of positive temperature coefficient (PTC).
Thermistor of PTC connects with terminals MT and GND. If motor is overheating, the keypad displays the
error code of OH4.
08-35=0: Fault selection of motor overheating is disabled.
08-35=1, 2:
Motor stop running while fault of motor overheating occurs.
Protection of motor overheating is enabled when the motor temperature rises, and the MT voltage level is
higher than 08-42 PTC trip level and the reach of delay time set by 08-39. The keypad will display an
“OH4
Motor overheat” and fault output is active.
When the motor temperature falls, and the MT voltage level is lower than 08-43 PTC reset level, it can
reset
‘’OH4 Motor overheat.’’
