Advanced Operating Functions
8.17 Synchronous Transfer
It is not required that all motors connected to a drive configured for synchronous transfer have
matching ratings. If mismatched motors are implemented, the drive must be sized for the worst
case load. "Smaller" motor loads can be mechanized via parameter read/write functionality or
the NXGPro+ control multiple configuration file capability, as described in Chapter Operating the
Software. As a rule, the smallest motor rating should be greater than 50% of the ratings of the
largest motor to ensure feedback signal integrity. When mismatched motors are used, the
proper configuration file must be active for the subject motor.
