Overview of closed-loop control
● Sensing of the actual position value on the slave can be performed using:
● The encoder interface must be configured in the process data.
● The control loop is closed via the PROFIBUS.
● The position controller is located on the master.
● The current and speed control systems and actual value sensing (encoder interface) are
● The position controller cycle is transferred via the fieldbus to the slaves.
● The slaves synchronize their speed and/or current controller cycle with the position
● The speed setpoint is specified by the master.
