Notice: The communication of the figure above can be 485 communications

(communication card and I/O expansion card) and CAN communication (I/O

expansion card).

Master-slave speed synchronization is used for two motor running synchronously. The

function requires two inverters both with pulse encoder feedback.

Master-slave speed synchronization function is comparing position counting values of the

master and the slave. The deviation for the slave can be reduced to zero by adding a

velocity correction given which is calculated by PID proportion coefficients one (Pb.11) and

integral time one (Pb.12).

When position deviation exceeds Pb.29 (speed synchronous position error dead zone),

the collection of slave is valid. If the correction value exceeds Pb.30 (speed synchronous

regulator output limit), it will be limited to Pb.30. If position deviation of the master and

slave exceeds Pb.28 (speed synchronous position deviation fault limit), the slave brakes

and displays “ELS” on the keypad.

The speed of the slave is lower than Pb.31 (the minimum speed of speed synchronous

output enable); the collection of slave is invalid. (Position deviations are still detected and

will be used when new start command is given.)

Master-slave speed synchronization can enable and cut off by an external signal 19: the

external signal is connected to the slave.

When the master-slave speed synchronous enables, only the host have start command

and speed given is valid. The host sends start commands and speed given to the slave
