7.6.6 PRESELECTION OF FREELY PROGRAMMABLE DIGITAL INPUT C112
FUNCTION OF FREELY PROGRAMMABLE DIGITAL INPUT C113
The digital inputs E1 to E5 can be assigned to the various functions to be selected in
C113. For this, first select the input to be assigned using code C112. If for example
the digital input E2 is preselected with C112 = -2-, the function "Trip-Set" can be
assigned to the terminal using C113
= -4-.
Allfunctions can only be assigned once. To activate the JOG references and the
additional Ti times, up to four terminals can be used. In addition, the polarity and the
priority can be changed using C114 and C115
(see 7.6.71.
7.6.7 POLARITYOF DIGITALINPUT
PRIORITYOF DIGITALINPUT
Using
C114, you can choose whether HIGHor LOWsignals are active for the digital
inputs E1 to E5.
C115 is used to determine whether the preselected input terminal with its function is
always active or, is switched off depending on the operating mode (see 7.1.1 I. If a
digital input terminal
is assigned a priority (terminal always activel with C115 = -1-,
the terminal terminal signal overwrites an information entered via the keypad or the
LECOMinterface.
Caution: The settings of polarity and priority refer to the selected signal. They are
lost when the function of the terminalis changed, i.e. with every new
assignment the factory settings are activated.
The factory setting of the polarity for "Trip-Set" (C113 = -4-1is not safe against
wire breakage.
