between the master and the slave.

2) The master use speed control and the slave use torque control under this

situation. The master sends output torque (output current) to the slave as the

torque reference. At the same time, the slave receives running frequency of the host,

and then compares with its own frequency to do PID error calculation, whose result

will be used as the slave’s adjustment current torque 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.

If set P0.11=6, the master-slave power equilibrium host mode is valid when the inverter

master-slave power equilibrium control mode is host under master-slave speed control

host mode.

Digital terminal S1 and S2 control crane running up and down. If inverter receives two

directions simultaneously, it will coast to stop; keypad will not display the fault information.

Fault output of the slave should be connected to the external fault terminal of the host.

Master-slave power equilibrium host mode parameter settings are as follows:
