IDN76 Position Data Scaling Type
Defines the scaling options for all position data. The supported scaling types are:
Preferred Scaling:
Fixed velocity data scaling (IDN45 = 1, IDN46 = -4)
Fixed position data scaling (IDN77 = 1, IDN78 = -7)
Parameter Scaling:
Adjustable velocity data scaling (IDN44, 45, 46)
Adjustable position data scaling (IDN77, 78)

Linear scaling and Modulo exclude each other. With linear scaling, the software limit
switches are automatically switched on (refer to IDN49, 50, 55 and P3004).
If rotational scaling is selected and the rotational position resolution (IDN79) is different
from the internal scaling (2
X
with X= {16,...,28}), the modulo format must be switched on,
this will be done during run-up.
With set the operation mode within IDN32 or 33 to position control with external feedback,
this IDN will set to 004A(Hex) as a fixed setting. The amplifier can only operate with a
fixed rotational scaling for the position data in this case (refer to IDN79).
