This allows the output flange to be locked in position and having 10096 repeatability at each index 3 VARIOUS OPERATIONS 3 1 Normal Operation Normal operation is regarded as the movement of the output flange in a direction from one dwell position to the next The rotational direction of the output flange is determined by the rotational direction of the drive With a three phase motor this can easily be reversed by swapping two phases of the supply voltage 3 1 1 Intermittent Operation The drive shaft stops in the dwell phase The step time is fixed The dwell period is variable This mode of operation is used in plants with much longer processing times than rotating times and is the most common mode of operation 3 1 2 Continuous Operation The rotary table runs continuously without the motor stopping Index and dwell times are fixed and run through continuously The drive motor has only one rotational direction This mode of operation is frequently used in high production plants which require short processing times The rotary index table is synchronized to the rest of the plant mechanically by means of free drive shaft The relationship between dwell and index time can be adjusted within certain limits by Motion Index Drives Inc when producing the barrel cam 3 1 3 Continuous Reversing Oscillating Operation The drive of the index table is always reversed in the dwell phase With this kind of model of operation the drive f
