Chapter 4 Operation and Display
In the above figure, the function code of communication timeout time (P8-04) is set
to a value other than 0, that is, the function of automatic shutdown of the inverter
after the communication timeout fault is activated, which can avoid the failure of
the communication line or the failure of the host computer. The frequency conver-
ter is running uncontrolled. This feature can be turned on in some applications.
The MODBUS-RTU slave protocol is built into the communication port of the inver-
ter, and the host computer must use the MODBUS-RTU master protocol to comm-
unicate with it. For the specific communication protocol definition, please refer to
Appendix A: KD600 Modbus Communication Protocol of this manual.
There are 3 start modes of the inverter, namely direct start, speed tracking start
and asynchronous motor pre-excitation start, which are selected by function par-
ameter P1-00.
P1-00=0, direct start mode, suitable for most small inertia loads, the frequency
curve of the start process is as shown in the figure below. The "DC braking" func-
tion before starting is suitable for the drive of elevators and heavy loads; the "sta-
rting frequency" is suitable for the drive of equipment that needs starting torque
shock start, such as cement mixer equipment.
