Functional principle of indirect positioning and synchronization

Description

2.3.5

SyncCrane solution indirect synchronization to virtual master encoder

Due to the mentioned positive characteristics in relation to indirect positioning, we are
currently testing if this can also be applied to synchronous operation.

We are working on the approach to superimpose a higher-level control loop for slip
compensation on the firmware function "internal synchronous operation".

Internal control loop: Angular synchronous operation of the motor encoder

Angular synchronous operation is ensured by using the "internal synchronous
operation" technology function.

The specified value for the virtual master is created via SBus object from the MOVI-
PLC

®

. The optimum master value is ensured for the physical axes because the master

value can be specified with limited jerk. 

The controller parameters can be set "hard" by direct coupling of the drive trains.

Higher-level control loop: Indirect synchronization

To prevent mechanical strain, e.g. caused by slight differences in the crane wheel diam-
eter of gantry cranes, the actual position value read in via an absolute encoder must be
compared with the position setpoint of the virtual encoder and corrected if necessary.
This is implemented by the higher-level indirect synchronization.

The cyclically calculated difference value triggers a compensation movement if specified
position windows are exceeded (distinction is made between dynamic and static case).
The dynamics of the compensation movement is set during startup.

The following figure shows indirect synchronization.
