7.2.5
Zero clamp (An.04, An.14, An.24)
Through capacitive as well as inductive coupling on the input lines or voltage fluctuations of the signal source,
the motor connected to the inverter can still drift (tremble) during standstill in spite of the analog input filter. It is
the task of the zero clamp to suppress this.
With the parameters An.04 / 14 / 24 the respective analog signals can be faded out within a range of 0...±10%.
The adjusted value is valid for positive and negative input signals.
If a negative percent value is adjusted the hysteresis acts in addition to the zero point around the current set-
point. Setpoint changes are accepted only if they are larger than the adjusted hysteresis.

Gain of the input characteristics (An.05...07, An.15...17, An.25...27)
With these parameters the input signals can be adapted in X and Y direction as well as in the rise to the requi-
rements. In the case of factory setting no zero point offset is adjusted, the rise (gain) is 1, i.e. the input value
corresponds to the output value of this step (see Fig. 7.2.6.a). The output value is calculated according to
following formula:
Out = Amplification • ( In - Offset X) + Offset Y

Brief description analog outputs
The KEB COMBIVERT has three programmable outputs (ANOUT1, 2 and ANOUT3, 4). Parameters An.31/36
allow the selection of one size which is given out at the outputs X2A.5 / 6. ANOUT 3 and ANOUT 4 (An.41 / 47)
may be output as switching condition 42, or 43 with the digital outputsas PWM signal. The analog signals can
be adapted to the requirements with the characteristic amplifier (An.33...35 / An.38...40 / 43...45/ 49...51).The
ru-parameters show the current size before and after the amplification. The period time for the PWM-signal can
be adjusted with An.46 / 52.

Process variables, that change only slowly, as for example the power module temperature, can be output over
two virtual analog outputs (ANOUT3 and 4). This is realised through generation of a PWM-signal (pulse-width-
modulation) on a digital output. Period T can be adjusted with parameter An.46 or An.52 „ANOUT period“ of

The characteristic amplifier are following after selecting the signal to be given out (see fig. 7.2.9). With these
parameters the input signals can be adapted in X and Y direction as well as in the rise to the requirements. With
factory setting no zero point offset is adjusted, the gain is 1, i.e. 100% of the variable to be given out correspond

Summary description digital inputs
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.00, whether external inputs shall be con-
trolled in PNP or NPN (not at safety relais) wiring. Parameter ru.21 shows the currently controlled input. Each
input can optionally (di.01) be set via terminal strip or by means of software with di.02. A digital filter (di. 03,
di.23) reduces the interference susceptibility of the inputs. The inputs can be inverted with di.04 and with di.05
one can switch to edge-triggering. With the parameters di. 06...di. 08 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-trigge-
ring, inversion and strobe signal can be adjusted but have no influence.

Setting of digital inputs by software (di.01, di.02)
With the aid of parameter di.01 and di.02 the digital input can be set without external wiring.
The control release must generally be switched by means of hardware even if one switches by software (see
Fig. 7.3.3 AND-operation with di.02 and sy.50)!

As shown in Fig. 7.3.3, it can be selected with di.01, whether the inputs shall be switched from the terminal
strip (default) or by way of parameter di.02. Both parameters are bit-coded, i.e. according to following table, the
appropriate value for the input is to be entered. In the case of several inputs the sum is to be formed.
(Exception: Control release must always be bridged at the terminal strip).

Input terminal state (ru.21), internal input state (ru.22)
The input terminal state (ru.21) displays the logical level of the input terminals. It is unimportant, whether the
inputs are internally active or not. If a terminal is controlled, then the appropriate decimal value according to the
table below is output. If several terminals are active, then the sum of the decimal values is output.
The internal input state (ru.22) shows the logic condition of the digital inputs which are internally set for pro-
cessing. If an input is set, the appropriate decimal value according to the table under 7.3.1 is output. If several
inputs are set, then the sum of the decimal values is output.
7.3.5
Digital noise filter (di.03), fast dig. noise filter (di.23)
The digital filter reduces the susceptibility to interferences on the digital inputs. Only hardware inputs can be
filtered. Each input port has a separate filter counter, counting upward for active ports and downward for inac-
tive ports. The output of the filter is set when the filter time is reached and is reset at zero.

7.3.6
Input logic (di.04)
With parameter di.04 it can be adjusted, whether a signal is 1- or 0-active (inverted). The parameter is bit-
coded, i.e. the value belonging to this input must be entered. If several inputs shall be inverted, then the sum is
to be formed. (Exception: An inversion of the control release remains without function.)
7.3.7
Input trigger (di.05)
As a standard the inverter is controlled with static signals, i.e. an input is set for as long as a signal is applied.
However, practice has shown that a signal may be available for a limited time only, but the input shall still remain
set. In that case the input or several inputs can be adjusted to edge-triggered flip-flop. Then a rising edge with
a pulse duration that is longer than the response time of the digital filter is sufficient for switch-on. Switch-off is
effected with the next rising edge.
Control release (ST) can be set to edge-triggered flip-flop, but remains without affect on the function, since it is
a pure static signal.

Strobe-dependent inputs (di.06, di.07, di.08)
A Strobe signal is used mainly for triggering the input signals. For example, two inputs shall be used for the
parameter set selection. But the signals for the control do not arrive exactly even, so for a short time it would
be switched into an unintended set. With active strobe (scanning signal) the current input signals of the strobe-
dependent inputs are accepted and kept until the next scanning.
Which inputs are switched by strobe?
With di.08 any input can be selected as strobe-dependent input. With the control release di.08 has no function
since this is a static input.
From where comes the strobe signal?
With parameter di.06 the strobe input is set. If several inputs are adjusted as strobe they are linked in OR-
operation.
Edge-active or static strobe?
As a standard the strobe is edge-active, i.e. the input conditions on the strobe input are accepted with rising
edge and maintained until the next increase edge. For some applications it is sensible to use the strobe in a
manner of a gate function. In that case the strobe signal is static, i.e. the input signals are accepted for as long
as the strobe signal is set (or for as long as the gate is open).

7.3.10Error reset / input selection and edge evaluation (di.09 / di.10)
With di.09 the reset input is defined according to the table under 7.3.1. If the reset input shall react to an edge,
one or several of the reset inputs defined with di.09 can be switched to edge evaluation with di.10.

7.3.11 Assignment of the inputs
There are two strictly different procedures for the assignment of inputs.
a.) Each function can be associated with one or more inputs. I.e., for each function (positioning, constant
selection, etc.) an input can be selected that activates this function.
b.) Each digital input can be associated with one or more functions. I.e.,each digital input can be associated
with one or more functions for the parameters di.11...di.22 "function" and di.24...di.35 "+ function". For
the parameters di.11...di.22 each input can be associated with multiple functions, for the parameters
di.24...di.35 only one function can be selected.
Both variants mutually influence each other; i.e., if an input is associated with a function, the parameters di.11...
di.22 and di.24...di.35 are adjusted accordingly .
Because of the two variants, the control combines two advantages:
-
with the functional programming of the inputs, the function's parametrization also permits selecting
which inputs will activate the function,
-
with the input-oriented display one gets a complete overview of the functionality of an input and can
check whether there are any unwanted interactions between functions.
