6-5 Encoder Dividing Function
Outline of Operation
 The number of output pulses from the drive can be adjusted.
 You can set the number of pulses per motor rotation in the range of 1 to (the number of encoder
resolution pulses).
 This function is used in the following cases:
   - When you use a controller with a low response frequency
   - When you want to set the pulse rate corresponding to a certain value
Example: Set the encoder dividing ratio to 2,000 (pulses/rotation) for when the 
resolution is set to 5 μm/pulse on mechanical systems that travel 10 mm per 
motor rotation.
