Objective ET16: Describe the homing sequence of each motor type

Match the descriptions below to the appropriate motor axis:

Motor Type and applications Homing sequence

_________ The motor drives until the flag enters

the sensor. The motor reverses

direction until the flag just leaves the

sensor. The motor drives again until

the flag sits inside the sensor. The

motor stops.

___________ There is no home sequence

___________ The motor reverses direction for a

pre-determined time duration. This

results in the motor stalling. The

motor drive then drives and stops.

___________ The motor drives until the flag enters

the sensor. The motor reverses

direction until the flag just leaves the

sensor. The motor stops.
