. Why the host computer and inverter have abnormal communication?
Ⅷ
(T) Check if the data format, address and baud rate are consistent with the host computer
(T) Check if the host computer address needs to be added by T (that is,"Address +T")
(3) Check if the host computer adopts Modbus RTU format
(4) Check if the register address of the host computer is converted to hexadecimal format
(5) Check if the 485 wires are properly connected
. Why there exist ab
Ⅸ
(T) The parameters forE5, V5 and V6 series cannot be copied between each other
(T) The copy operation can be performed only when the parameter value of dT.09 (operation panel copy
identification code) are consistent
(3) After download, should completely power off and power on again, the parameters copy is completed
. Why the operation panel displayed .8.8.8.8. or no display?
Ⅹ
(T) Check if the operation panel are properly connected to the control board
(T) Check if the network cable adopt straight-through connection between the operation panel and control
board
Ⅺ Why the operation panel can not see the parameter or can not change parameter value? .
(T) If the parameter value can not changed, check if P0.0T is set to T. If is set to T, change it to 0.
(T) Check if the parameter is only read
(3) If change parameter in running status, check if the parameter could not be changed in running status
(4) When display is not available, check if the parameter has been encrypted
(5) When display is not available, check if the operation panel has been locked
. How to change th
Ⅻ
(T) If run command channel is operation panel, setting P0.07 or press FWDTREV key on the operation panel
to change the motor running direction in real time
(T) If run command channel is terminal, motor running direction is determine by the terminal command
(3) Operation panel UPTDN key or terminal UPTDN can change the running direction,for details, refer to the
parameter of Pb.08 and Pb.T0 descriptions
(4) PID control and composite control can change the motor direction, or details, refer to the parameter of
P8.08 description
XIII. Why some model inverter, the fans will run after power on, and some not after power on?
E5−H series:
(T) T5kW and below power class: The fan will run after power on
(T) T8.5kW to 45kW : The fan is controlled by the heat-sink temperature
(3) 55kW to 75kW : The fan will run after power on
(4) 90kW and above power class: The fan is controlled by the heat-sink temperature and running
