Digital In- and Outputs
The KEB COMBIVERT F4-F has 7 external digital inputs, 6 of these inputs are
programmable (I1...I6). In addition to that the unit has 4 internal programmable
inputs (IA...ID), which are directly linked with the internal outputs.
Coming from the terminal strip it can be defined with parameter dr.1 whether the
inputs are triggered in PNP or NPN circuits. Parameter ru.14 shows the actually
activated terminals. Each input can be set optionally (di.15) by way of terminal strip
or by software with di.16. A digital filter (di.0) reduces the interference susceptibility
of the inputs. With di.2 the inputs can be inverted. With the parameters di.17...di.19
a strobe mode can be activated. The input status (ru.16) indicates the inputs that
are actually set for processing. The function, which is performed by a programmable
input, is defined with di.3...di.6, di.11 and di.12. The internal inputs are directly
controlled by the internal outputs. Their function is defined with di.7...di.10.

For safety reasons the control
release (ST) must generally be
operated by hardware. Edge
triggering and strobe signal can
be adjusted but have no effect.
