This section only applies when an NAIO module is connected to an
ACS 600 equipped with Standard Application Program version 2.8 to
3.0. Users of other application programs should refer to the drive
manuals.
Before adjusting the parameters, ensure that the module node number
is set to 4. Note that the setting takes effect only on the following
module power-up.
98.6 AI/O EXT
MODULE 1
This parameter activates the communication between the ACS 600 and
the NAIO module.
YES (Std. Application Program versions up to 3.0b)
NAIO-01; NAIO-02 (Std. Application Program versions 3.0c to 3.0f)
Analogue input 1 of the module replaces standard analogue input AI3.
Analogue input 2 of the module replaces standard analogue input AI2.
Analogue output 1 of the module replaces standard analogue output
AO1.
Analogue output 1 of the module replaces standard analogue output
AO2.
NO
Communication is not active or module not present.
Note: The ACS 600 assumes that the signals connected to the
analogue inputs 2 and 3 are always current signals because the
standard inputs are fixed that way. It is possible, however, to connect a
voltage signal to the module input. In case the real input is a voltage
signal, the panel will display the input signal incorrectly. A real value 10
V will be displayed as 20 mA. This must be considered when scaling
the signals or reading the actual value of the AI2 and AI3.
Example: The input signal is scaled by setting the signal minimum and
maximum values with the parameters in Group 13 ANALOGUE
INPUTS. If the actual signal on AI2 of the module is a voltage signal,
the setting of Parameter 13.11 MINIMUM AI2 to 0 mA corresponds to
actual minimum 0 V and the setting 4 mA corresponds to actual
minimum 2 V. The maximum setting 20 mA corresponds to actual
maximum 10 V.
Parameter Group 13
Analogue Inputs
The parameters in Group 13 define the minimum and maximum values
of the input signals, the signal scaling factors, the signal filtering time
constants and the signal inversion. For more information see the
ACS 600 Programming Manual.
Parameter Group 15
Analogue Outputs
The parameters in Group 15 define the actual analogue output signals,
the signal minimum values, the signal scaling factors and the signal
filtering time constants. For more information see the ACS 600
Programming Manual.
