2. In the Param window, click the Operator pull-down menu in the left column and
select Manufacturer.
3. Set the following parameters:
o Encoder Direction: Indicates the direction of the axis encoders. 1: positive
direction; -1: negative direction
o Encoder digits: Indicates the digit number of the servo motor encoder.
Value range: 10–29.
o Electronic gear ratio(numerator)/Electronic gear ratio(denominator):
Indicates whether the servo drive enlarges or shrinks the received pulse
frequency from the upper computer. If the Electronic gear
ratio(numerator)/Electronic gear ratio(denominator) value is larger than 1,
the servo drive enlarges the pulse frequency. If the Electronic gear
ratio(numerator)/Electronic gear ratio(denominator) value is smaller than
1, the servo drive shrinks the pulse frequency.
o Pitch: The movement or rotation angle of the feed axis per lead screw turn.
3.5 Check Axis Direction
Determine the positive direction for the machine axes based on the right-hand rule and
check to see if the axis directions are correct to avoid possible damage.
Taking the X axis as an example, follow the steps below to check the axis direction:
1. Determine the X axis positive direction based on the right-hand rule.
2. In the menu bar, go to System > Global Parameters.
