Lifting applications

Perform the following additional steps before starting up the lifting applications:

  1. WARNING! Danger from falling hoist. Severe or fatal injuries. Observe the following information.
    • Do not use the device alone as a safety device for the lifting application.
    • Use additional monitoring systems or mechanical protection devices as a safety device.
  2. WARNING! Danger from falling hoist. Severe or fatal injuries. Do not use the "Release brake/deactivate DynaStop® for FCB01" function in lifting devices or applications with loads that may potentially fall down. Disable the function as follows:
    • Disable the function via parameter Functions > Drive functions > FCB01 Output stage inhibit > Release brake/deactivate DynaStop® for FCB01 – enable = "0" (No).
  3. In the MOVISUITE® engineering software, configure the parameters according to the lifting application requirements and its safety assessment.
    • Set the parameter Functions > Drive functions > FCB01 Output stage inhibit > Apply brake with STO = "1" (Yes).
  4. Check the setting of the parameter Drive train > Drive train DTx > Controller > Motor behavior > Hoist preload in the MOVISUITE® engineering software. Set the parameter in accordance with the lifting application requirements.
  5. The Hoist preload parameter influences the integrator behavior of the speed controller in its initial value reentering control. The following can be selected:
    "off" (= default): The integrator always starts with the value "0". Any existing load torque is compensated.
    "Save": The integrator value that was present at the time of opening the speed control loop is retained. If the load torque has not changed, no adjustment is necessary when closing the speed control loop.
    "Initialization value": If the load torque is known, you can specify this to the speed controller as an initial value via the parameter "Torque preload" in the range -1000 to 1000% of the nominal motor torque. This can be done during startup or optimization of the drive with the MOVISUITE® engineering software or you can use a local setpoint or a channel of the process data buffer. If the direction of rotation is positive in the stroke direction, enter a positive value and vice versa.
  6. Check the setting of the parameter Functions > Monitoring functions > Control functions > Speed monitoring > Delay time in the MOVISUITE® engineering software. Set the parameter in accordance with the lifting application requirements. SEW-EURODRIVE recommends setting the Delay time parameter to a value ≤ 100 ms.
