Only a variable parameter that is not protected can be specified. If any
other type of parameter is specified, the input is not assigned to any
parameter.

By default, the input is calibrated so that 9.8V sets
7.01
at 100%. Use the
following procedure to change the full-scale value:
1
Apply the required full-scale value to terminals 2 and 3, as follows:
•
If the applied value is greater than 2.5V, it will become the new
full-scale value
•
If the applied value is less than 1.5V, the new full-scale value will be
the default value (9.8V)
2
Set
7.25
at 1.
The input scaling automatically changes according to the applied value
(see step 1). This new value will set
7.01
at 100% and will remain
effective until this procedure is next performed.
The new setting is saved at power-down.

7.26
for the
best compromise between low-speed operation and dynamic response.
Low values give good dynamic response but noisy operation at low speeds.
High values give smooth low-speed operation but a poorer dynamic
response.
