Dividing ratio = INT
The INT function extracts an integer from the fraction. The non-integer
remainder is rounded.

The CP1L CPU Units have two functions that can be used to determine the
machine origin for positioning.
1,2,3... 1. Origin Search
The ORG instruction outputs pulses to turn the motor according to the pat-
tern specified in the origin search parameters. As the motor turns, the ori-
gin search function determines the machine origin from the following 3
kinds of position input signals.
• Origin input signal
• Origin proximity input signal
• CW limit input signal and CCW limit input signal
