Question

Give the number of time the 4 step sequence must be applied to a stepper motor to make a 96 degree move in the motor has a 2-degree step angle. a. 10 four-step sequence consecutively b. 96 steps sequence consecutively c. 12 four-step sequence consecutively d. none of the above e. a and c only What is access time? a. It is the Read cycle time of the memory chip b. It is the delay of the memory chip c. It is the speed of the memory chip d. It is the wait time of the memory chip e. all of the above

Explanation / Answer

1. In the given, the stepper motor make to move 96° for 4step sequence and have a step angle of 2°. So we can easily understand that one step take 2° angle and stepper motor is having 4 step sequence, so every move has 4 steps and it must do 96° for one move. 4 steps means 4*one step angle= 4*2°= 8° for one move.... So we can find that how many moves are consequently done for 96° move 8°* (No. Of consequent times) =96° No. Of consequent times=96/8=12 times

So answer is C

12 times of consequent 4step sequence with 2°step angle gives 96° for a move

Verify:

12time 4step sequence 2° angle

12*4*2=96°

2)Acces time:

Answer is A

It is the time taken for access or read the memory from the target
