2.7 Additional functions for Thyro-A

Applying the bus module provides access to further data on the controller (e.g. para-
meters, actual values). It is thus possible to perform additional application functions.
The data, which can be accessed via the bus module, is specified in the correspon-
ding bus module operating instructions.
Examples:
In order to achieve a narrower line width with a line recorder the output signal can
be smoothed as required.
Sliding mean value for the analog output
MEAN
(Default setting: with VAR mains periods, with TAKT 100 pulse periods)
For the operating modes TAKT and VAR control limits (final position limit) can be
set:
Control limits
Ts max, Ts min
V_IE, H_IE
If required the controller's parameters can be adjusted to the route:
Control parameters
TI
20
KP
60
A function of Thyro-A which is often used in the TAKT operating mode is the software
synchronization (mains load optimization). A numerical value can be entered via IN-
DEX 38 (SYNC_ADR) which is multiplied by 10ms or 8.33ms (duration of a mains
half wave) and results in a delay time up to the first connection.
Mains load optimization with SYNC_ADR
(50Hz) =>
delay time after mains recovery 10ms
(60Hz) =>
delay time after mains recovery 8.33ms * 100 = 833ms
100
with TAKT
with VAR
(default value)
(default value)
* 100 = 1000ms
(Default setting: 100)
