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:
    • Deactivate the function of DIP switch S1/2 via parameter Functions > Inputs/outputs > Basic device > DIP switch functions > Release brake/deactivate DynaStop® for FCB01 – enable > Deactivation = "1" (yes).
    • Disable the function via parameter Functions > Drive functions > FCB01 Output stage inhibit > Release brake/deactivate DynaStop® for FCB01 – enable = "0" (No).
  3. WARNING! The DynaStop® electrodynamic retarding function does not allow for a definite stop at a position. Severe or fatal injuries. Observe the following information.
    • Do not use drive units with DynaStop® in lifting applications.
    • When using DynaStop® on ascending/descending sections or vertical conveyors without freely suspended loads, comply with the basic safety and health requirements (e.g. EC Machinery Directive 2006/42/EC).
    • The behavior of the DynaStop® function must be taken into account for the risk assessment of the application that determines the required safety measures.
  4. 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).
    • Set the parameter Functions > Drive functions > FCB01 Output stage inhibit > Activate with DynaStop® according to the requirements of the application. Observe the notes in chapter "DynaStop® in conjunction with STO".
  5. 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.
    • The Hoist preload parameter influences the integrator behavior of the speed controller in its initial value reentering control. The following settings are available:
    • "Off" (= default): The integrator always starts with the value "0".
      Adjustment is made to an existing load torque.
    • "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": With the "Torque preload" parameter, you can specify the load torque to the speed controller as the initial value in the range -1000% – 1000% of the nominal motor torque. You can set this parameter during startup or optimization of the drive. As an alternative, you can use a local setpoint or a channel of the process data buffer for this purpose. If the direction of rotation is positive in the stroke direction, enter a positive value and vice versa.
  6. Set the parameter Functions > Monitoring functions > Control functions > Speed monitoring > Delay time according to the requirements of the application. SEW-EURODRIVE recommends setting the Delay time parameter to a value ≤ 100 ms.
