Motor load test
Task:
In order to verify a motor design, the motor is to be loaded by cyclic reversing in a long-term
test.
Solution:
The GP function "Binary logic" (
) serves to configure the logic function
"NOT". This inverts the output of the delay element (
) and thus
generates an alternating signal. The alternating signal in turn is connected to the
application input for change of direction of rotation (
bSetSpeedCcw
) and causes an
alternating direction of rotation of the motor.
