7.3.12Software ST and locking of the control release
di.36 software ST, di.37 ST lock, di.38 turn off ST delay time
The function is switched off, if no input is selected in di.36. ST can not be selected as software ST or input for
locking.
With the locking function the control release can be controlled in case of voltage failure (even if the controlled
PLC is failure) as long as e.g. Power off function needs for stopping the drive.
Condition: terminal ST must be bridged !
Switching off an input (selection in di.36) is decelerated for the time adjusted in di.38. Within this time the lo-
cking input (selection into di.37) must be active in order to secure the function.
A software input e.g. (IA-ID) can be assigned with the function Power off (do.00...do.07 = 17, switching condi-
tion for OA-OD) as locking input.

7.3.13Deactivation of the digital control release
With the digital input selection (di.01 / di.02) or the control word (SY.43/ SY.50) the control release can be trig-
gered digitally (e.g., via a bus system). Additionally, terminal ST must always be active.
In parameter di.39, "turn off ST input selection", an input can be selected for deactivating the digital setting of
the control release . Thus, only terminal ST is active.
That way, it is possible to implement manual operation in case of bus system failure.

Digital In- and Outputs
Description
For the switching of the digital outputs one can choose up to 8 conditions from the 91 different conditions.
These are entered in do.00...do.07. Switching condition 0 and 1 can be filtered by do.43 and do.44. Parameter
ru.23 shows, if one or several of these conditions are met.For each flag it can now be selected which of the 8
conditions shall apply to it (do.16...do.23). Each condition can still be inverted before selection (do.08...do.15).
As a standard, all conditions (if several are selected) are OR-operated. With do.24 this can be changed to
AND-operation, i.e. all conditions selected for this flag must be fulfilled before it is set. Parameter ru.24 shows
the flags which are set in this stage. do.33...40 form a second logic step with which a selection of the flags from
logic step 1 can be made. Every individual condition can be inverted with do..25...32. do.41 adjusts the manner
of the linkage (AND/OR). Parameter do.42 is used for inverting one or several outputs. With do.51 the output
signals are assigned to the terminals. ru.80 serves for the display of the status prior to allocation, thereafter
ru.25. The internal outputs OA...OD are directly connected with the internal inputs IA...ID.

The total current of X2A.18, 19 is limited to 50mA. In case of inductive load at the relay outputs or at the tran-
sistor output a protective wiring is to be provided (free-wheeling diode)!
7.3.16Output filter (do.43, do.44)
With do.43 a filter can be set for switching condition 0. With do.44 for switching condition 1. The change of a
switching condition must be applied for the filter time, then it becomes active at the output of the filter. If the
change of a switching condition is cancelled during the filter time, the filter time is reset and restarted at the next
change. The filter time can be adjusted in a range of 0 (off)...1000 ms.

With the parameters do.08...do.15 each of the 8 switching conditions (do.00...do.07) can be inverted for each
flag separately. Through this function it is possible to set any chosen switching condition as Non-condition.The
parameter is bit-coded.According to Fig. 7.3.15 the weighting of the switching conditions to be inverted must be
entered in do.08...do.15. If several conditions shall be inverted, the sum is to be formed.
Example:
Output X2A.19 shall be set when the inverter is not accelerating! In this case we assign the switching condition
21 (inverter accelerates) for example to do.01 (enter value 21). We invert the switching condition (do.01) with
do.09, so enter value 2.
7.3.19Selection of switching conditions for flags 0...7 (do.16...do.23)
The parameters do.16...do.23 serve for the selection of the 8 defined switching conditions. The selection is
done for each flag separately, where one can choose between no one and up to all 8 switching conditions.
According to Fig. 7.3.15 the weighting of the selected switching conditions is to be entered into do.16...do.23.
If several conditions shall be inverted, the sum is to be formed.
7.3.20Linking the switching conditions for flags (do.24)
After the switching conditions are selected for each output, it can now be determined, how these are linked.
As a default all conditions are OR-operated, i.e. if one of the selected conditions is met, the flag is set. Another
possibility is the AND-operation which can be adjusted with do.24. AND-operation means that all selected con-
ditions must be fulfilled before the flag is set.
Parameter do.24 is bit-coded. The table under 7.3.17 shows the assignment.

With the parameters do.25...do.32 each of the 8 flags (bit 0...7) from logic step 1 can be inverted separately.
Through this function it is possible to set any chosen flag as Non-flag. The parameter is bit-coded. According
to Fig.7.3.18 the weighting of the flag to be inverted must be entered in do.25...do.32. If several flags shall be
inverted, the sum is to be formed.

In the second logic step a selection of the flags of the first logic step can be made.The selection is done for

the weighting of the selected flags is to be entered into do.33...do.40. If several flags shall be inverted, the sum

After the switching conditions are selected for each output, it can now be determined, how these are linked. As
a default all flags are OR-operated, i.e. if one of the selected flags is met, the output switches.Another possibi-
lity is the AND-operation which can be adjusted with do.41. AND-operation means, that all selected flags must
be set before the output switches.

7.3.26Programming example
For a better understanding, the correlations are explained on the basis of a little more complex example.Following
conditions are required:
•
Condition 1: Output X2A.19 switches, if the inverter accelerates
•
Condition 2: Relay X2A.24...26 switches, if the inverter load is > 100 %
•
Condition 3: Relay X2A.27...29
•
Output X2A.18 switches, if the conditions 2 and 3 are realised, but the inverter does not accelerate.
Solution proposal:
Set switching conditions, levels and hysteresis
First set the switching conditions and levels.
Set do.00 to "21" (inverter accelerates)
Set do.01 to "24" ((inverter utilization > level); set LE.01 to "100" (load level for do.01 100 %); set LE.09 to "5"
(5 % hysteresis for level 1; not required but reasonable for optimal switching performance).
Set do.02 to "27" (actual value > level); set LE.02 to "4" (frequency level for do.02); set LE.10 to "0,5" (0.5 Hz
hysteresis for level 2;not required but reasonable for optimal switching performance).
Select switching conditions
Set do.16 to "1" (evaluate switching condition of do.0)
Set do.17 to "2 (evaluate switching condition of do.1)
Set do.18 to "4" (evaluate switching condition of do.2)
Set do.8, do.9 and do.10 to "0" (no inverting)
The setting of do.24 is independent for this example, as only one condition each is set at do.16...18.
Set flags
Output O1 (terminal X2A.18)
Set do.33 to "7"(evaluate flags 1...3)
Set do.25 to "1"(flag 1 is inverted, it means that the condition is fulfilled if the inverter does not accelerate).
Set do.41 to "1" (the flags selected with do.33 become AND-operated)
Output O2 (terminal X2A.19)
Set do.34 to "1" (evaluate flag 3)
Set do.26 to "0" (no inverting)
The setting of do.41 is independent for this example, as only one flag is set at do.34.
Relay output R1 (terminal X2A.24...26)
Set do.35 to "2"(evaluate flag)
Set do.27 to "0" (no inverting)
The setting of do.41 is independent for this example, as only one flag is set at do.35.
Relay output R2 (terminal X2A.27...29)
Set do.36 to "4"(evaluate flag)
Set do.28 to "0" (no inverting)
The setting of do.41 is independent for this example, as only one flag is set at do.36.

Summary description
The setpoint of the KEB COMBIVERT F5 can be preadjusted analog as well as digital. The AUX-function adds
or multiplies an analog setpoint to/with other setpoint settings.
The setpoint and rotation selection links the different setpoint sources with the possible sources of rotation
direction. The signal thus obtained is used for further setpoint calculation.
Only after interrogation of the absolute setpoint limits, all the data that is required for the ramp calculation is
available.

structions.
Page7.4 - 4
Setpoint-, Rotation- and Ramp Adjustment
Other functions like quick stop, fixed frequency, or positioning have priority over "standard operation" and can
therefore lead to different speed setpoints than selected in oP.00 .
The following speed setpoint limiting blocks can change the setpoint.
Direct analog setpoint setting (AN1 direct)
The cycle time of the software is 1 ms. During this time the analog input/output status is updated once. Addi-
tionally the inverter requires a processing time of 1... 3 ms before the new setpoint value is calculated. If the
inverter is used as secondary final control element of a superior control, this time can impair the dynamics of
the entire closed-loop control system.
In such cases the analog setpoint value can be processed directly to the control processor (direct setpoint ad-
justment). Thus a sampling time of 250 µs is possible.To enable this fast response to an analog setpoint value,
some restrictions must be accepted:
• The calculation formula of the analog setpoint value changes. The parameters oP.06 / oP.07 are without
influence on the setpoint calculation.
percentage analog value = (analog value/10V x 100% - An.06) x An.05
This value is limited to +/- 100%.
set = limited analog value in percent x oP.10
n
This value is limited with oP.14 for both directions of rotation.
• The setpoint limitations oP.06 / oP.07 / oP.11 do not have any function; the frequency setpoint is only limited
by oP. 14 (for both directions).
• The acceleration / deceleration and S-curve time have no effect; it is operated internally without ramps.
• The parameters An.01...04 and An.07...09 are without any function.
• The stop position controller cannot be activated.
7
High resolution reference setting
The setpoint setting with the settings oP.00 = 0...9 is 16 Bit wide. This results in a maximum resolution of 0.125
rpm in 4000-rpm-mode (ud.02 = 4 and 8).
For applications needing a higher resolution, the high resolution setpoint setting was introduced. Here, the
setpoint is set as a 32-Bit-value.
Since only a 16-Bit-value can be output, the low-order 16 bits of the ramp output value are upsampled. On
overrun, the base value is increased for one cycle (1 ms) (by 0.125 rpm in 4000-rpm-mode). These setpoint
fluctuations are smoothed mechanically, leading to the higher average resolution.
To achieve the highest possible resolution for the application, two parameters can be used:
oP.64 Relative value high-resolution
The parameter oP.64 sets the reference value of the calculation and is dependent on ud.02.
