The robot incorporates motor overcurrent protection into the Z servo controller.
When an overcurrent situation is detected, the corresponding servo is shut-off and an
error message is generated. This protection is a safety feature designed to prevent
blown fuses due to excessive load; i.e. the robot arm is obstructed during a regular
move or jog move.
