No.
5.0 s / real32
Defines safe motor speed ramp setting used when
automatic process control mode is active.
In order to prevent undesired speed steps due to
process feedback signal errors or any other reason, it
is recommended to set this parameter value as high
as it seems reasonable it terms of expected speed
change dynamics.

1000.0 / real32
Defines the value for the process 1 feedback and
reference unit scaling.
It is assumed that the process signal might change in
range from 0 to a value set in this parameter. This
setting only serves for rendering process unit to the
percent scale and does not limit the input in any way.
Note: When this parameter is set to 0, the process 1
feedback and set point reference scaling is bypassed.
The values are then taken to the process PI controller
input.
