Operation

3-6-5 Backlash Compensation

H Functions
• The backlash compensation function absorbs mechanical looseness by creating a gap between the
detection angles in the CW and CCW directions.
• If a compensation value equivalent to the mechanical looseness is set, the cam outputs can match the
mechanical position.
• This function is effective for machinery that rotate in both directions. Backlash compensation is not
required for machinery that rotates in one direction only.
• If backlash compensation values are set, the display will not change until the machine has rotated in
the opposite direction through a number of degrees for the backlash compensation amount.
• The backlash compensation function operates when the "backlash compensation enable/disable" pa-
rameter is set to "enable."

• Use this parameter to set the angle equivalent to the mechanical looseness (backlash).
• The factory setting is "0."
Note 1. The numeric values for 720 (divisions/rotation) resolution are shown in parentheses.
Note 2. This parameter is enabled when the power is turned OFF and then turned ON again.
