Programming with convenient and
easy-to-understand instructions
Uses a preset value table for starting speed, target speed,
acceleration/ deceleration time, and other factors. Easy-to-
understand programming is possible since numbers can be
specified intuitively.
Comes with dedicated instructions for each mode: trapezoidal
control, home return, JOG operation, free table operation,
linear interpolation, and circular interpolation.
Selectable home return mode
The home return method may be specified even in situations
such as when only a single sensor is being used, depending
on the design.
When the home position return is completed, a deviation
counter clear signal can also be output.

Home search automatically reverses the motor rotation when
Over limit input(+) or Over limit input (-) is input and their
searches for the home position or near home position in order
to return to it automatically.
This refers to an operation in which the motor is rotated only
while operation commands are being input. This is used to
forcibly rotate the motor using input from an external switch, for
instance when making adjustments. Depending on the
circumstances, unlimited feeding can be accomplished with the
JOG operation in some cases.

also available.
A control function that automatically defines the continuum of
points in a straight line based on only two co-ordinate positions.
Allows points to be smoothly traversed by arced paths for which
the user specifies the orientation plane, the radius of curvature,
motion path profile, and direction of motion.
