Applied Functions
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.
