Digital controller RK 4004
.4.4. pos source adress
In the case of follow-up controlling (master/slave) a second actuator
(slave) without sensor scanning precisely follows up a freely selecta-
ble actuator (master). The device address of the master's guider must
be entered on the controller card of the second actuator (slave).
Example:
The master's address is 1.5
The slave's address is 2.5
Value 15 (address 1.5) must be entered in parameter .4.4. of the sla-
ve controller card (address 2.5).
.4.5. prop stroke ±
In the case of integral actuators the correction path is set in relation
to the set proportional range (parameter ".1.3. prop range ±").
This parameter has no function for proportional actuators.
The greater the set correction path is for a constant proportional ran-
ge (parameter ".1.3. prop range ±"), the greater the amplification
(steep characteristic curve) of the web guider in automatic mode.
The steeper the characteristic curve the longer the correction path in
the event of a control deviation and thus the more sensitive the sy-
stem will become. The correction path used by the actuator to try to
correct an error may be seen in the characteristic curve.
