Notice:

1) Example one above is application control diagram for flexible load drive. The

master and slave are connected by belts or other extendable materials (flexible

load). Due to ductility of materials, some speed error between master and slave is

permitted.

2) The master and slave both use speed control under this situation. The host

sends the running frequency to the slave as frequency reference. At the same time,

the slave receives current output torque (output current) of the host, and then

compares with its own torque to do PID error calculation whose result will be used

as the adjustment for the slave’s current frequency reference. The master and slave

can realize synchronization control and power balance at last.

3) In the master-slave control mode, the running command of the host is connected

to fault signals of the slave, once the slave is fault; the host is not allowed to run.

4) There are three types mode for PID calculations of the slave depending on

specific applications.

5) The meaning of F_m> Pb.24 is to make sure that the slave starts PID calculation

after the host starts to prevent PID initial calculation accumulation of slave before

host starting.

Example two for master-slave control:

Notice:

1) Example two above is application control diagram for rigid load drive. The

connection between the master and the slave is fixed. It should be no speed error
