 How to choose the appropriate servo drive?


The servo drive has to supply the motor with the required current (rated current at continuous operation, peak current) and match the terminal voltage of the motor (125 V, 320 V, or 560 V). Also the intended purpose is important for the choice of the right drive


Is the servo drive going to be used in velocity mode in a multi-axis application with a higher-level controller (e. g. CNC)? Then an analog servo drive may be sufficient.


Or should the drive be equipped with more functionality (e. g. for positioning control or axis synchronization) or a fieldbus (e. g. Interbus, CANopen, or Profibus-DP) for communication with the higher-level controller? In this case a digital servo drive has to be used.
