FCB concept

FCB = Function Control Block

The FCB concept describes the modular firmware design of inverters from the MOVI-C® modular automation system with which it is ensured that a wide range of drive functions can be selected or deselected quickly and easily using control words.

All primary functions are selected as FCBs. For example, positioning control requires FCB 09, while speed control is implemented with FCB 05.

You can switch between different FCBs at any time. Switching to another FCB takes place with a maximum delay of 0.5 ms.

Different priorities are assigned to the FCBs. If an FCB with a higher priority than the currently active FCB is selected, the FCB with the higher priority is activated.

The FCBs are sorted in descending order of their priority in the following list:

  • FCB 01 Output stage inhibit
  • FCB 14 Emergency stop
  • FCB 13 Stop at application limits
  • FCB 18 Rotor position identification
  • FCB 25 Motor parameter measurement
  • FCB 12 Reference travel
  • FCB 04 Manual mode
  • FCB 20 Jog mode
  • FCB 19 Position hold control
  • FCB 21 Brake test
  • FCB 10 Interpolated position control
  • FCB 09 Position control
  • FCB 06 Interpolated speed control
  • FCB 05 Speed control
  • FCB 08 Interpolated torque control
  • FCB 07 Torque control
  • FCB 26 Stop at user limits
  • FCB 02 Default stop
