Technical description 8100_A
7.6.25 WINDOW FOR DIGITALOUTPUTACTUALVALUE
= SET-VALUEC240
In closed-Ioop operation, the functions "actual value = set-value" indicates that the
system deviation (difference between set-value and actual value) is within a certain
specified range. The display range is designed as a window, which is positioned
above and below the switching threshold. The width of this window can be specified
using C240. The value is referenced to fdmax (C011) and operates with a hysteresis
of 0.4%.
In open-Ioop operation, the function "actual value = set-value" is mapped to the
signal "ramp function generator input = output". The signal actual value
= set-value
can be assigned to one of the digital output terminals.
7.6.26 WINDOW FOR DIGITAL OUTPUT "RAMP GENERATOR
INPUT = OUTPUT C241
As soon as the actual field frequency has reached the set frequency, the signal
"ramp function generator input = output" is activated. For this, enter the size of a
target window in per cent of the set-value with C241. The signal operates with a
hysteresis of 0.4%.
The signal ramp function generator input
= output can be assigned to one of the
digital output terminals with C117.
7.6.27 LECOM1
-CODE BANKC249
Codes up to C255 can be processed with version 1.0 of the LECOMAlB protocol. To
be able to reach codes of higher numbers with this version, the access range can be
switched with code C249. Code C249 exists in all code ranges.
Further information about serial communication with the standard interface LECOM 1
(LECOMAlB) is contained in the LECOMAlB technical description, which we would
be pleased to send on request.
