Adjustment of controlled system gain

V
is not represented by the "servo trace" function if the setpoint is defined
set
by the function generator.
S
The setting must be checked at different velocities.
-
Generally speaking, the average value of the calculated controlled
system gain must be set or
-
the gain can be adjusted to match the relevant operating range.
S
Both adjustment are equivalent, i.e. adjustment by the stage 2 method via
MD 5462 and MD 5463 produces equivalent results when the preset value
(setting) of the controlled system gain (MD 5435) is applied.
