timing control for motor

[Atul_Goyal]

Hi,

I am developing a VI that needs an output motor to be switched "ON" for some fixed timing. Like If an event is sensed using a sensor, the motor should run for exactly 2 minutes and then stop. Please help how to achieve it and what logic or function should be used to achieve this.

Thanks to all of you in advance.

Hi Atul,

the motor should run for exactly 2 minutes and then stop

Please define "exactly"! Is it in the order of seconds or is it nanoseconds?

My advice is to use a state machine to switch this motor ON and OFF. And use ElapsedTime to start and stop your timer…

Hi Atul,

Frist write a simulation code with State machine architecture. You can find the template for State machine here. Use Elapse time or Wait Until Next ms Multiple for timing control( In this method you can get 1ms accuracy). If every thing working fine in this simulation, change your code to interface hardware.
