  • Page 3: Introduction

    Document purpose It provides guidance for commissioning permanent magnet synchronous motors (PMSM) with SINAMICS G120X drives using the IOP-2 interface. Despite the fact the PMSM motors are not standardized and the optimal performance with G120X drive cannot be always guaranteed most party PMSM motors that meet the criteria described in this guide can be successfully commissioned.

    2 General conditions of operation Motor data required for commissioning For correct automatic setting of motor model and control loop parameters some important data must be entered into the inverter during commissioning. They can usually be found either on the motor nameplate or in the datasheet provided by the motor supplier: Table 2-1 Parameter name...

  • Page 8: Operation With A Sine-Wave Filter

    2 General conditions of operation Operation with a sine-wave filter Currently only G120X FSA-G support sine-wave filters. Basically a sine-wave filter with a PMSM motor can be used however the operation with long cables may lead to instability and without making a customer specific test the operation cannot be guaranteed.

  • Page 17: Appendix 1: Guidance On Commissioning Lspm - Line Started Permanent Magnet Motors

    4 Appendix 1: Guidance on commissioning LSPM (Line Started Permanent Magnet motors) Appendix 1: Guidance on commissioning LSPM (Line Started Permanent Magnet motors) LSPM are special kind of PM motors comprising also the rotor cage. It allows to connect this motors D.O.L. (direct on line) similarly to asynchronous motors. Once the motor speed is close to synchronous speed the rotor magnets cause locking into synchronism and successive operation as synchronous motor.
