Startup with LSPM motors from SEW‑EURODRIVE

DR..J type motors are motors with LSPM technology (Line Start Permanent Magnet motors).

  1. Connect the motor to the inverter. Adhere to the nominal motor voltage when connecting.
  2. Enter the motor data from the motor nameplate:
    • P1-07 = Internal voltage/no-load voltage [V/min-1] at nominal motor speed
    • P1-08 = Rated current of the motor
    • P1-09 = Rated frequency of the motor
    • P1-10 = Rated speed of the motor
    • P1-14 = 201 (extended parameter menu)
    • P4-01 = 6 (LSPM speed control).
  3. Set the maximum speed P1-01 and minimum speed P1-02 = 300 min-1.
  4. Set the acceleration and deceleration ramps using P1-03 and P1-04.
  5. Start the "Auto-tune" automatic motor measuring procedure as described in chapter Automatic measuring procedure ("Auto-tune").
  6. Adjust the boost parameters. A default setting is:
    • P7-14 = 10%
    • P7-15 = 10%.
  7. In case of insufficient control performance, the control behavior can be optimized via the parameter P7-10.
