Use synchronization signal

  • Menu: 4.2.1-2.1-1

Description

Specifies whether the synchronization signal of the higher-level controller is to be used. The synchronization signal allows for precise synchronization between the stations of the following bus networks:

  • EtherCAT®/SBusPLUS
  • PROFINET with IRT communication (Isochronous Real Time)
  • POWERLINK

Synchronization information is only transferred when the bus is connected directly.

Whether a synchronization signal is useful or not depends on the specific application. In applications where servo drives travel along geometrical paths, for example, using a synchronization signal is the basic requirement for simultaneous interrelated movements of the axes.

Synchronized process data exchange must be performed in the following interpolating drive functions:

  • FCB 06 Interpolated speed control
  • FCB 08 Interpolated torque control
  • FCB 10 Interpolated position control

The following settings are possible:

Setting

Meaning

1 (yes)

Process data is applied in a synchronous manner.

0 (no)

The synchronization signal is not evaluated.

1 (yes)
