FPΣ (Sigma) Positioning

High-speed, high precision positioning

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.

JOG operation

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.

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.
