Assigning control commands
You can assign the control commands via the PO structure.
Example of jog mode:
The right drive is enabled with the command
RightMDRControl.Run_MDR
.
You can select the direction of rotation with the command
RightMDRCon-
trol.MDR_Direction
:
•
#PO.RightMDRControl.Run_MDR:= true;
•
#PO.RightMDRControl.MDR_Direction:= false;
You can set the setpoint speed, acceleration, and deceleration with numerical values:
•
#PO.RightMDRSpeed:= xxx;
•
#PO.RightMDRAccel:= xxx;
•
#PO.RightMDRDeccel:= xxx;
Processing actual values
You can retrieve the actual values from the PI structure.
With the help of the structure of the command
PI.LeftMDRDiagnostic
, you can
evaluate the error bits of the left drive:
•
#PI.LeftMDRDiagnostic.Overheat;
•
#PI.LeftMDRDiagnostic.MaxTorque;
