Hello, I faced with a problem that lab10e-flying start delays at startup even i try to run the motor right after enabling the system. After approximately 3-4 seconds motor starts running in set speed. My friend suggested that program may be performing some calibrations at start up that preventing motor to run at the beginning. I took a look but couldnot find such calibration work or any other thing to cause delay and few weeks passed without solution because i had to work on someother stuff so any suggestions where should i look to prevent time delay?

Please make sure RsRecalc is disabled as it will run during motor startup

Hello Sean,

thanks for fast response and sorry for my delay.

I have definitely tried that but i still get 3-4 seconds delay. I wonder the reason, i believe program does some pre-calibrations because i see that from the expressions, cpu_time changes directly after running the code.

thanks in advance.
