WLSU

DescriptionSets the event condition and halts the execution of the TML program from motion controller until the slave’s load speed is equal or under the 32-bit value or the value of the specified fixed variable. After you have programmed an event, you can do the following actions:
•Change the motion mode and/or the parameters when the event occurs, with command UPD!
•Stop the motion when the event occurs, with command STOP.

The programmed event is automatically erased when the event occurs or if the timeout for wait expires.

 

ExecutionActivates the monitoring of the event when load speed <= value32, respectively VAR32. The motion controller application remains in a loop until the event on the slave axis occurs or it timeouts. This operation erases a previous programmed event that has occurred.

Example                

// Start a position profile when load speed < 600 rpm

// Load Position feedback: 500 lines encoder (2000 counts/rev)

WLSU (A) 20; //Set event: when motor speed is < 600 rpm

// prepare new motion mode

(A)

CACC = 0.3183;//acceleration rate = 1000[rad/s^2]

CSPD = 100;//slew speed = 3000[rpm]

CPOS = 20000;//position command = 10[rot]

CPR; //position command is relative

MODE PP;

TUM1; //set Target Update Mode 1

UPD;
