Appendix II Instruction of the Proportional
Linkage Function
II-1. Proportional linkage function:
The proportion interaction host computer:
Communication address = 128,
Communications port A is the communication port of host computer.
Communication port B can be used as the keyboard interface, or a PC host computer interface.
There is only one host inverter in one proportional linkage.
The host inverter control the running state, the slave inverter follow the host‟s running state.
The proportion interaction slave computer:
Communication Address = 1 ~ 127,
Both communication port A and communication port B can be the communication port of
slave inverter.
In the slave inverter follow the host running and it can realize forced stopping by terminal or
keyboard if need.
For this function, the host computer should be set with the following parameters:
Local communication address
For this function, the slave computer should be set with the following parameters:
