*A .5 SEC MIN DELAY IS REQUIRED AFTER THE MOTOR ON LINE IS ACTIVATED.
**THIS DELAY IS NECESSARY IF DRIVE SELECT IS USED TO LOAD HEADS. OTHERWISE A
35 MS MIN DELAY IS REQUIRED AFTER THE HEAD LOAD LINE BECOMES ACTIVE.
IF HEAD LOAD IS NOT USED TO ENABLE THE STEPPER MOTOR THEN A 15 MS MIN DELAY
IS REQUIRED FOR STEPPER SETTING AFTER ENABLING THE STEPPER MOTOR.
NOTE: TIMES SHOWN ARE MINIMUM TIMES EXCEPT AS NOTED.
