CFW700 | 13-5
P0233 – AI1 Signal Type
P0238 – AI2 Signal Type
Adjustable
Range:
0 = 0 to 10 V / 20 mA
1 = 4 to 20 mA
2 = 10 V / 20 mA to 0
3 = 20 to 4 mA
4 = -10 V to +10 V
Factory
Setting:
0
Properties: cfg
Access groups
via HMI:
I/O
Description:
These parameters configure the signal type (if it is current or voltage) that will be read at each analog input, as
well as its range. Refer to the
tables 13.1 and 13.2 for more details on this configuration.
Table 13.1: DIP Switches related to the analog inputs
Parameter Input Switch Location
P0233 AI1 S1.2
Control Board
P0238 AI2 S1.1
Table 13.2: Configuration of the analog input signals
P0238, P0233 Input Signal Switch Position
0 (0 to 10) V / (0 to 20) mA Off/On
1 (4 to 20) mA On
2 (10 to 0) V / (20 to 0) mA Off/On
3 (20 to 4) mA On
4 (-10 to +10) V Off
When current signals are used at the input, the switch corresponding to the desired input must be set in the
“ON” position.
Inverse reference is obtained with the options 2 and 3, i.e., maximum speed is obtained with minimum reference.
13.1.2 Analog Outputs
In the CFW700 standard configuration are available 2 analog outputs (AO1 and AO2). The parameters related to
those outputs are described next.
P0014 – AO1 Value
P0015 – AO2 Value
Adjustable
Range:
0.00 to 100.00 % Factory
Setting:
Properties: ro
Access groups
via HMI:
I/O or READ
Description:
Those read only parameters indicate the value of the analog outputs AO1 and AO2, as a percentage of the full
scale. The indicated values are those obtained after the multiplication by the gain. Refer to the description of
the parameters P0251 to P0256.
