Digital In- and Outputs
The KEB COMBIVERT has 8 external digital inputs and 4 internal inputs (IA...ID).
All inputs can be assigned to one or several functions.
Coming from the terminal strip it can be defined with parameter di.0 (not at F5-B),
whether external inputs shall be controlled in PNP or NPN (not at safety relais)
wiring. Parameter ru.21 shows the currently controlled input. Each input can optionally
(di.1) be set via terminal strip or by means of software with di.2. A digital filter (di.3)
reduces the interference susceptibility of the inputs. The inputs can be inverted
with di.4 and with di.5 one can switch to edge-triggering. With the parameters di. 6...di. 8
a Strobe-mode can be activated. The input status (ru.22) shows the inputs that are
actually set for processing. The function(s), that a programmed input carries out, is
defined by means of the input selection of the corresponding function or by di.11...22.
For safety reasons the control release (ST) must generally be switched by means of
hardware. Edge-triggering, inversion and strobe signal can be adjusted but have no
influence.
