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;
