# Behaviour of the slave axis at the modulo limit

The behaviour of the slave at the modulo limit must be specially defined.

By default, the slave will always move within its modulo limits, i.e. it maximally undergoes one revolution in the same direction.

If an endlessly rotating slave is required, either "EndlessPositive" or "EndlessNegative" must be specified in the start mode of the FB MC_CamIn. The slave will then endlessly rotate beyond the modulo limit in the positive or negative direction of rotation.

Cases for all three variants with regard to the behaviour of the slave axis at the modulo limit are shown in Figures 2, 3 and 4.

## Example

The following camming table was used in all three examples:

Tablename = Smallest_Table # Table name

Table-ID = 404 # Table-ID

Tabletype = 7 # Table type, 7= 2-column, SGN32 format

Functiontype = 4 # Interpol. type, 4= LINE-POLY5, 5= POLY5-LINE

Lines = 2 # Number of lines

Begintable # Beginning of table

100000 0

1500000 3400000

EndTable
