Motor Synchronizatioin

Keya Khan Posts: 2 Rating: (0)	How can I synchronize two motor with two individual VFD. by varying a "POT" from one VFD same speed will vary of the another motor.It's a simple wrapping machine application. MM440 / SINAMICS V20 which will be better selection for this. Please answer.

PISCEAN 2010 Posts: 8092 Rating: (884)	Hello, Just suggestion. You can use 1 M440 of capacity equals or little bit greater than thesum of current of two motors. So with 1pot & 1 MM440 you can get the same speed? Why you want to use 2 MM440? Are motors ofequal ratings or of different capacities?

Hello Deep, Nice suggestion but i would say, for better synchronization, Master Slave is best option so its better to do in the way Ste39suggested.
