Activating the function

In case the output stage is inhibited, you can release the brake by a control signal (digital input or process data bit) using the function "Release brake with FCB 01". For example, this allows to move loads freely using a horizontal conveyor.

Now make the following settings:

  1. Enabling the function:
    • Via parameter settings
    • Enable the function "Release brake with FCB 01 – enable" by setting the parameter Release brake with FCB 01 – enable to = "1" [1].
    • (Path: Functions > Drive functions > FCB 01 Output stage inhibit)
  3. Configuring the control signal:
    • Control via a digital input
    • Assign the function "Release brake with FCB 01" [2] to a digital input.
    • Control via a process data bit
    • Assign the function "Release brake with FCB 01" [3] to a process data bit.

WARNING

Hazard from falling loads.
Severe or fatal injuries.
  • Do not use the function "Release brake with FCB 01" for hoist applications and applications with potentially falling loads.
  • Inhibit the function via the following steps:
    • Inhibit the function using the parameter Release brake with FCB 01 – enable = "0" (path: Functions > Drive functions > FCB 01 Output stage inhibit).

The set control signal can be used to release the brake when the function block FCB01 is active.
