Hi everyone
I have a question, can the amps trigger return a boolean value? That is, it can return a value true if the trigger trigger is activated? Or false if not activated

This is possible via MicroBasic script

I understand that it is possible with Microbasic, but how? I have only seen that the activation of the amps trigger can take some of these actions:
0: No action
1:Safety stop
2: Emergency stop
3: Motor stop
4: Forward limit switch
5: Reverse limit switch
6: Invert direction
7: Run MicroBasic script
8: Load counter with home value
But I need to use it as a bool variable, false if not activated, true if activated

You would simply monitor the motor current and if the current reaches above a chosen limit then you would set a variable to true. See a sample below:

' Reads the controllers motor current and then sets the level of a boolean variable based on the level


option explicit 'Force variable declaration

'Variable declarations
dim AmpsLimit as integer
dim Motor1_Amps as integer
dim AmpsTrigger as boolean

AmpsLimit = 500 'Sets the amps trigger level to 50A, change as needed (Amps * 10)



'main loop
Top:

Motor1_Amps = getvalue(_A, 1) 'Query the current seen on motor channel 1 (pg 230 of manual)

if Motor1_Amps >= AmpsLimit then  'See IF functions described on pg 193 of manual
	
	AmpsTrigger = True
	
else
	
	AmpsTrigger = False
	
end if

wait(10) 'loop every 10 milliseconds, 100Hz)

goto Top 'go to top of loop

Because getvalue(_A , 1) returns an integer a simple line like getvalue(_A, 1) >= 500 should return the Boolean your looking for.
This should work in any place you want a logical true or false

Also uses less lines of code and fewer declared variables. With memory at a low limit
