User Manual of EM760 High-Performance Inverter When the current exceeds the overcurrent detection level (F15.66) and the duration reaches F15.67,the function “73: output overcurrent” of the output terminal will be valid. 6.6.10 Cooling fan control In order to use the fan reasonably, the fan system has three running modes, depending on the fan control function code (F15.34). The specific running mode ofthe fan is shown below. Table 6-17 Details of Fan Operation When “2: intelligent operation, subject to temperature control” is selected, make sure that the temperature detection module of the inverter works properly.
If low-speed fan running mode is enabled, the fan of a high-power model will run at low speed to reduce noise; and if low-speed fan running mode is disabled, the fan will of a high-power model will run at full speed. 153 Function code Function codename Parameter description Unit Default setting Attribute F15.34 Fan control Ones place: Fan control mode 0: running after power-on 1: running at startup 2: intelligent operation, subject to temperature control Tens place: Electrification fan control 0: Run 1 minute first and then enter the fan control mode for running 1: Directly run in the fan control mode Hundreds place: Low-speed fan running mode enabled (200G/220P~400G/450P) 0:
Low-speed running invalid 1: Low-speed running valid 101 O Fan control Fan operation 0: running after power-on When the inverter is powered on, the fan will start running. 1: running at startup When the inverter starts running, the fan will start running. When this parameter is set to 1 min, the fan will stop running. 2: intelligent operation, subject to temperature control When the temperature of the inverter is greater than 45°C, the fan will start running; when the temperature of the inverter is less than 40℃, the fan will stop running; and when the temperature of the inverter is in between the two values, the fan will remain unchanged.
