7.14.10 Parameter: CAM Slave Scaling (0x3809)

The axis supports scaling in slave direction. The scaling factor consists of a numerator and a denominator. The value 0x0000
0000 must be reserved and cannot be used for the numerator and the denominator objects. A writing order is defined so
that both values can be changed simultaneously. The activation of the new factor is done after the writing of the
numerator. This means to change both values at the same time, the denominator must be written first and the numerator
afterwards. It is also possible to only change the numerator by just writing a new value (the denominator remains the
same).
Guide value scaling (master) and CAM slave scaling can be used in parallel. The numerator and the denominator accept
negative values. The division of 2 negative values results in a positive value. The slave position is multiplied by the quotient
of numerator and denominator.
