Instruction manual 91/121 V6.3
Commissioning
Set the multiplication factor of the “Value” signal in input to the calibration block. With this parameter you can amplify or reduce the
input signal to suit your needs. See drawing 16 to figure out where this parameter works in the calculation.
An.Out. X Offset
Minimum Maximum Units of measure
-10.00
+10.00
%
Set the value to add to the “Value” signal to create an outgoing offset. See drawing 16 to figure out where this parameter works in the
calculation.
An.Out. X Abs
With this parameter you can select whether to take the “Value” or its value without sign as input of the calibration block of the analog
output. The selections available are:
•
FALSE: The “Value” signal is used directly with the positive or negative sign.
•
TRUE: The “Value” signal is used as an absolute value (without sign), so always positive.
By activating this function it is possible to have an analog output always positive (or negative, just set the “Gain” with a negative
number), in case of use with unmarked display tools. See Drawing 16 to figure out where this parameter works in the calculation.
Digital inputs
Menu group to configure and calibrate digital inputs. For simplicity it is advisable to see the following figure showing the internal cal -
ibration structure of a generic digital input. The logical state of the terminal associated with the digital input is read and then you can
then select whether to send the direct or logically reversed value out of the block.
Digital Input X
Menu group to configure the digital input X. Changes to the calibration values made in this group, act exclusively on the indicated di -
gital input and not on the others.
Dig.Inp. X Dest
Parameter that allows you to select the destination of the “Value” signal of the digital input. The possible selections are:
•
NOT USED
: not used.
•
Rev.Speed Ref
.: sent to the ramp block to control the reversal of the speed reference sign.
•
ASW1 Inp Sel
: Sent to the “Analog Switch 1” block to command analogue input selection (see section 5.6.11 on page 68).
•
ASW2 Inp Sel:
Sent to the "Analog Switch2“ block to command analogue input selection (see section 5.6.11 on page 68).
•
ASW3 Inp Sel:
Sent to the "Analog Switch3“ block to command analogue input selection (see section 5.6.11 on page 68).
•
ASW4 Inp Sel:
Sent to the "Analog Switch4“ block to command analogue input selection (see section 5.6.11 on page 68).
•
Disable Summ1
: The digital input controls the input of “Disable sum 1” into the summing block (see paragraph 5.6.10 on
page 67).
•
Disable Summ2
: The digital input controls the input of “deactivation sum 2” into the summing block (see paragraph 5.6.10
on page 67).
NOTE:
If two or more different digital inputs are accidentally assigned to the same function, the one that has priority over the oth-
ers is the one with the highest number (e.g.: input DI3 has priority over input DI1).
Dig.Inp. X Sign
With this parameter you can select whether to reverse the read logical state from the associated digital input or to leave it as originally.
The possible selections are:
•
NORMAL: The “Value” signal indicates exactly the logical state of the associated digital input.
•
REVERSE: The “Value” signal is logically reversed with respect to the logical state of the associated digital input.
See Drawing 17 for more clarity.
Dig.Inp. X Value
Read-only parameter that indicates the logical state outgoing from the compensation block of the digital input. See drawing 17 for
more clarity.
