Dear sir...

I am using 2 no of AC Motors for my machine operation and both motors are same rating. I am using separate SINAMICS PM340 drive with CU 310-2DP control unit for individual drives. I am using speed control encoder less operation for both drives. Since i dont now how to operate master/slave operation between drives i have configured both drives indipendent masters and working normal.some times based load requirements current drawn by individual drives were differ and operation not working smoothly. I want to configure first drive as MASTER and second drive as SLAVE. i.e i want to transfer data between Drive 1 to drive 2 . I am using S7 400 PLC to switch on and off drive. I request to expert team please help me how transfer data from 1 drive to other drive for master slave operation..

Hello,

CU310 is for single axis control as such master-slave control thru CU is not possible. You can control it via PLC. Please check.

Sir....i have tried with PLC i.e Actual current transferred from MASTER DRIVE to PLC and it was processed in PLC and sent to SLAVE as input of current controller.  I observed that SLAVE response was quite slow and machine heavy jolting happend. Without transferring data to PLC is there any other possibilities to send data..
