5-4 Encoder Dividing
 The number of pulses can be set for the encoder signals output from the Servo Drive.
 The number of pulses per Servomotor rotation can be set within a range of 1 to 2,500 pulses/
rotation.
 Use this function for the following applications:
 When using a controller with a low response frequency.
 When it is desirable to set a pulse rate that is easily divisible.
Example:
To use a resolution of 5 µm/pulse in a mechanical system in which one Servomotor rotation
corresponds to a travel of 10 mm, set the encoder dividing rate to 2,000 pulses/rotation.
Parameters Requiring Setting
Operation
The output phases of the encoder signal output from the Servo Drive are as shown below.
Parameter
No.
Parameter name Explanation Reference

Encoder Dividing
Rate Setting
Set the number of encoder pulses to be output from the Servo
Drive for each rotation. The default setting is 2,500 pulses/ro-
tation.
The setting can be made from 1 to 16,384 pulses/rotation, but
the setting will not be valid if it exceeds 2,500 pulses/rotation.
Even if the dividing rate is changed, there will always be 1
pulse per rotation for phase Z.
