07- 13 OH over heat Protection ( cooling fan control)
Range
【0】：Auto (Depends on temp.)
【1】：Operate while in RUN mode
【2】：Always Run
【3】：Disabled
1) 07-13=0：The fan runs as the inverter senses temperature rises. Thusly, extend the service period.
2 )07-13=1：The fan runs while the inverter is running.
3) 07-13=2：The fan is continuously running regardless of the action of the inverter.
4) 07-13=3：The fan is Disabled.
07- 18 OL2 protection reset time
Range
【1.0~10.0】min
When the fault protection is caused by the overload of the inverter, the duration of the jump is lower
than the set value of 07-18, and the manual reset cannot be carried out, so as to prevent the product
heat of the frequency converter IGBT module and affect the life of the frequency converter. The
frequency converter automatically resets when the duration of the jump is greater than 07-18.

1）RS-485 Communication：
a. One to one communication: A controller, PC or PLC, controls one inverter. (set 08-00 = 1~32)
b. One to many communication: A controller, PC or PLC ,controls multiple inverters (Up to 32
inverters as max. Set 08-00 = 1~32).
c. When any inverter receive the communication station number 0, from the PC or PLC
( Broadcast mode) then all these inverters will be controlled in communication mode regardless
of the setting of parameter 08-00.
2）RS-232communication: (RS232 interface is required)
a. One to One communication: A controller, PC or PLC, controls one inverter. (set 08-00 = 1~32)
b. Communication data parameters (08-02/08-03/08-04/8-05)for controller, PC or PLC and
inverters should all be set the same.
c. The inverter will confirm the validity of new parameters set by PC.
d. Please refer to the N310 Communication instruction manual for communication protocol.
Note: when 08-01=0, can not set 08-05=1.
