through communication (CAN or 485 bus). Acceleration and deceleration time of the slave

should be set equal to or less than that of the master. If there is no communication card,

the master and slave should use the same run command and speed given, acceleration

and deceleration time of the slave should be consistent with the master.

When the master-slave speed synchronization is cut off, the two inverters work in their

own "normal mode", if master-slave synchronous speed is separated or integrated when

the motor is running, the slave should decelerate to stop.

When gearbox reduction ratio of the master and slave is different, please set the value of

master/slave speed ratio as Pb.07 (the gain frequency reference of slave). When each

pulse corresponding to the distance of master/slave encoder output is different, Please

use Pb.26 and Pb.27 to set pulse speed ratio of master and slave.

Master/slave unit pulse speed ratio =Pb.26/Pb.27. This scale factor multiplies position

value of the slave only when the master-slave speed synchronization control is effective.

If set P0.11=8, the master-slave speed synchronization host mode is valid when the

inverter of the master-slave speed synchronization control mode is host under master-

slave speed synchronization 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 master should be connected to the external fault terminal of the slave.

Master-slave speed synchronous host mode parameter settings are as follows:
