9.7.4 Gain adjustment radius
When selecting the dancer-Position control with
evaluation of the setpoint, the gain of the radius
must be set
such that an appropriate output frequency is generated when
having a fixed
and a certain radius.
Coarse adjustment:
1. Before adjusting the radius the analog inputs must be
set.
2. Set CO25 = -l-.
3. Calculate correction factor C027:
Determine radius as a voltage value
= [mm]
Distance [V]
Distance a
Calculate CO27 (1.25 [V] is an internal calculation factor)
CO27
Distance a [mm]
[V] . Distance [V]
Example when using the values given in 9.7.1:
[V] = 150 mm . =
1000 mm
CO27 = = 1.042
1.2 v
4. Enter the calculated factor via C027.
In general, the gain of the radius is set in such way that the
is will not when having the radius.
