Outline
When performing positioning for a system in terms of absolute positions in
that system, it is first necessary to define the origin. For example, in the X-Y
plane shown below, before positioning to (X,Y) = (100 mm,200 mm), it neces-
sary to establish where the origin is, i.e., it is necessary to determine the ori-
gin.
With the PCU, the origin can be defined in the two ways given below.
In addition, the PCU also features the following origin reset function, which
can be used to reset the position to the origin set with the above methods.
The motor can be operated without determining the origin (although origin
return cannot be used). Operation will, however, proceed in the way described
below.
Name
Description
ORIGIN SEARCH
Using this method, the motor controlling movement
is actually operated and the origin is determined
using limit input signals, an origin proximity input
signal, and an origin input signal. A photoelectric
sensor or the Z-phase signal from an encoder can
be used as the origin input signal.
PRESENT POSITION
PRESET
The origin can be determined by forcibly setting the
position at which the motor is stopped to the
desired value.
Name
Description
ORIGIN RETURN
With the motor stopped, the position is reset to the
origin set by the origin search or present position
preset functions.
