1. Confirmation of speed and encoder resolution.

  2. Conversion of load torque on motor shaft and calculation of acceleration and deceleration torque.

  3. Calculate the load inertia, inertia matching, Yaskawa servo motor as an example, some products inertia matching up to 50 times, actually the smaller the better, it’s good to the accuracy and response speed .

  4. The calculation and selection of regenerative resistance, for servo, generally more than 2kW and external configuration are required .

  5. Cable selection, encoder cable twisted pair shield, for Yaskawa servo and other Japanese products, absolute encoder is 6-core, incremental is 4-core.
