ELSM®

SEW-EURODRIVE recommends the following settings and control behavior for using the drive unit in lifting applications with the ELSM® control mode:

Parameter settings:

  • For vertical drives, use the setpoint/stop function (FCB05 - speed control). Functions > Drive functions > FCB 05 Speed control > Stop by setpoint function > Activation = "1" (Yes).
    • Set the parameter Functions > Drive functions > FCB 05 Speed control > Stop by setpoint function > Stop setpoint so that the resulting motor speed is above the transition speed (2% of the nominal speed of the motor in operation).
    • As an alternative, set the parameter Functions > Drive functions > FCB 05 Speed control > Minimum speed so that the resulting motor speed is above the transition speed (2% of the nominal speed of the motor in operation).
  • Set the parameter Drive train > Drive train ASx > Controller > Control behavior > Flying start = "1" (On).
  • Set the parameter Functions > Monitoring functions > Limit values > Application limits > Torque ≥ 150% of the nominal motor torque.

Control behavior:

  • Design the control in such a way that a direction of rotation reversal is only possible in an idle state (with the brake applied).
  • If you want to change the direction of rotation without an idle state, use a drive with encoder.
  • Control the drive at a setpoint speed that corresponds to a speed above the transition speed (2% of the nominal speed of the motor in operation).
