6-5-1 Outline of the Function
6-5 Encoder Dividing Function
• The encoder dividing function enables you to adjust the number of output pulses from the Servo
Drive.
• The number of output pulses per motor rotation can be set in the range of 1 to the number of encoder
resolution pulses.
• This function is useful in the following cases:
• When you use a controller with a low response frequency
• When you want to set the pulse rate as a simple value
Example:If the encoder resolution is 5 µm/pulse in a mechanical system that generates a
movement of 10 mm per motor rotation, set the encoder dividing ratio to 2,000 (pulses/
rotation).
