Open loop

Open loop | Synchronous positioning

0x8280-01 – Setpoint operating mode

Operating mode: 8: Synchronous positioning

0x8F00-01 – Encoder feedback configuration

Open loop

0: Encoder value is 0 (fixed).

1: Encoder value is output in 0x8F00-02 – Encoder – Actual value.

0x8480-03 – Setpoint position

Specification of setpoint position

0x8F00-02 – Encoder – Actual value

The display is dependent on the setting in 0x8F00-01 – Encoder feedback configuration.

Open loop has the following features:

  • The function module operates in open-loop control mode.
  • The encoder signal is not taken into account by the controller.
  • The setpoint for the current controller is generated by interpolation of the synchronously specified position setpoint.
  • The actual position corresponds to the interpolated position value.
  • An encoder value is output depending on the setting in 0x8F00-01 – Encoder feedback configuration. For further information, refer to chapter Open loop.
