As far as I understand your qn, you want to understand basics of Synchronisation. Now there are few possibilities. 1) You are using Master Slave Mode. For this, read following thread to understand basics. https://www.automation.siemens.com/tf/WW/en/Posts/45039#top In drive, your Master drive will get Speed Setpoint and Slave drive will get Torque setpoint Normally, we give setpoint to Slave drive after RFG, means directly to Speed controller. For this, mostly Simolink is used. Most care should taken for this. I faced problems at some sites if disturbances from Power cable. You should isolate these cables properly 2) NO Master Slave. If PLC is giving setpoint to both drives, you can program in PLC for setpoint. You have to set identical Ramp-up, Ramp-down, Excitation, and De magnetising times. If all drives are running at diff frequenies, then Ramp times should be set accordingly but Excitation and De-excitation time should be same. Normal problems in this configuration comes from PLC. If your synchronisation is disturbed, check that you getting start command and Setpoint release at same(or proper) time In all case, you must perform Motor ID, Speed controller Tunning and Current Controller Tunning I hope you can understand basic and you got what you want Ask if any further Query Regards, Devesh |
