Origin Search and Origin Return Functions Section 6-3
Specifying the Origin
Search Direction (CW or
CCW Direction)
Sets the direction to move when detecting the Origin Input Signal.
Typically, the origin search is performed so that the Origin Input Signal's rising
edge is detected when moving in the origin search direction.
Origin Search Speed These are the motor speed settings used in the origin search.
Origin Search/Return Initial Speed
Sets the motor's starting speed when the origin search is executed. Specify
the speed in the number of pulses per second (pps).
Origin Search High Speed
Sets the motor's target speed when the origin search is executed. Specify the
speed in the number of pulses per second (pps).
Origin Search Proximity Speed
Sets the motor's speed after the Origin Proximity Input Signal is detected.
Specify the speed in the number of pulses per second (pps).
Origin Search Acceleration Rate
Sets the motor's acceleration rate when the origin search is executed. Specify
the amount to increase the speed (Hz) per 4-ms interval.
Origin Search Deceleration Rate
Sets the motor's acceleration rate when the origin search function is deceler-
ating. Specify the amount to decrease the speed (Hz) per 4-ms interval.
Origin Compensation After the origin has been determined, the origin compensation can be set to
compensate for a shift in the Proximity Sensor's ON position, motor replace-
ment, or other change.
Once the origin has been detected in an origin search, the number of pulses
specified in the origin compensation is output, the current position is reset to
0, and the pulse output's No-origin Flag is turned OFF.
2: Origin Proximity Input
Signal not used.
Note When the limit input signal is received, the motor stops without deceleration.
