Similarly, the profile can be stretched or compressed vertically, by
multiplying the Slave scale by a fraction C/D. If C/D is larger than
one, the profile will be stretched. If C/D is less than one, the profile
will be contracted.
♦ C, the numerator, is defined by the variable
ECAM_Slave_scale_num.
♦ D, the denominator, is defined by the variable
ECAM_Slave_scale_den.
The scaling factors cannot by changed while ECAM is engaged.
To apply scaling:
1. Set the variables ECAM_Master_scale_num,
ECAM_Master_scale_den, ECAM_Slave_scale_num and
ECAM_Slave_scale_den using the SET_VAR command.

When using a virtual axis, it is recommended that scaling only
be used to scale the graph down, that is, A/B and C/D should
be set to values lower than one. If a profile is stretched, a lack
of sufficient data points will result in a profile that is not
smooth. When designing a profile, you should therefore design
it for the largest movements that could possibly be required, so
that it will only ever be necessary to scale the profile down.

The scaling factors discussed above do not affect the size of the
shift or offset, if defined.
