Hello. As you post PLC diagnostic, I assume, your PLC controlling both drives. Look in the PLC program how the setpoints are formed for both drives. Then compare that setpoints inside drives. Look at themanual, chapter 8 'Function diagrams', sheet G152. Begin from parameter P625 and go back through all setpoint channel (G137, G136, G135 etc).
