3-6-8 One-direction Function
H Functions
• Enables cam outputs when the Resolver is rotating in one direction only, either forward or reverse. (If
the Resolver rotates in the opposite direction, the output status will be held.)
• This function can be set for any cam.
Note 1. The one-direction function is disabled when compensation operation, trial operation, or
teaching is being executed.
Note 2. When backlash compensation is enabled, the one-direction function works at the angle after
backlash compensation has been executed. (For example, even if the Resolver rotates in the
opposite direction, the system will not consider this as the reverse direction until the backlash
compensation amount has been exceeded.)
Note 3. When advance angle compensation is enabled, cam outputs are made at the angle after ad-
vance angle compensation has been made. Rotation direction for the one-direction function
is determined by the increasing or decreasing angles after backlash compensation has been
performed (the angle after advance angle compensation is not used to determine the rotation
direction). Therefore, even when the present angle is decreasing (when decelerating or due
to a reduction in the advance angle amount), this is not considered as reverse direction. (Re-
fer to 3-6-6 Advance Angle Compensation.)

Parameter
No.
--- Setting range 0 to 2
• Use this parameter to set or clear the one-direction function for each cam.
• The settings are as follows:
0: One-direction function disabled (factory setting)
1: Enabled in the forward direction (cam output status held when rotating in reverse)
2: Enabled in the reverse direction (cam output status held when rotating forward)
Note 1. This parameter is enabled when the power is turned OFF and then ON again.
Note 2. Use the CW/CCW setting switch to set either CW or CCW as the forward direction. Refer to
3-5-2 Initial Settings for details.
