Plc Motor Control Questions With All Correct
& Verified Answers
What is the one of the most common PLC applications? Correct answer-Start/stop constant electric
motors
What contacts need to be used to make sure seal-in logic is working properly and safe? Correct
answer-Auxiliary contacts
What controls fluid power motors? Correct answer-Directional control valve
A magnetic motor starter provides a safe method to channel the flow of current to the electric motor
by acting as this component. Correct answer-Switch
In Rockwell's CCW software, a discrete variable has a Data Type of this? Correct answer-BOOL
Seal-in logic keeps the output in what state when input is removed? Correct answer-On
Which is an example of the use of safety interlocks? Correct answer-Machine runs after all guards
are in place
Safety interlocks are used in machines to do what? Correct answer-All of the above
This provides the interface between the PLC and the starter contacts in a magnetic motor starter.
Correct answer-Solenoid
Assigning the input instructions the same address as the output instruction will allow for how many
step-sequence programs? Correct answer-Multiple
How does a safety interlock prevent an action? Correct answer-Interlock works only when another
action has taken place
Internal output addresses are known as memory coils, internal variables, and what else? Correct
answer-Memory bits
