Detailed Description of the Parameters
.
90 | CTW900
Besides the setting of these parameters, it is necessary to position correctly the DIP switches on the Control
Board or Accessory Board IOA-01, as shown in tables 7.10, 7.11 and 7.12.

For outputs AO1 and AO2, when current signals are used, the switch corresponding to the desired output must
be set to the “OFF” position.
For outputs AO3 and AO4, when current signals are used, the terminals AO3 (I) and AO4 (I) must be used. For
voltage signals, use the terminals AO3(V) and AO4(V). The switch corresponding to the desired output must be
set to “ON” only in order to use the range -10 to +10 V.
7.3.14
Digital Inputs [34]
For the drive and control of the converter by means of external physical commands, the standard version of the
CTW900 has six digital inputs, and two more can be optionally added with the accessories IOA-01 and IOB-01.
The parameters that configure these inputs are presented below.
P0012 – Status of Digital Inputs DI8 to DI1
Adjustable Range:
Bit 0 = DI1
Factory Setting:
Bit 1 = DI2
Bit 2 = DI3
Bit 3 = DI4
Bit 4 = DI5
Bit 5 = DI6
Bit 6 = DI7
Bit 7 = DI8

Description:
By means of this parameter it is possible to visualize the status of the six control board digital inputs (DI1 to DI6)
and of the two accessory board digital inputs (DI7 and DI8).
The indication is done by means of the numbers 1 and 0, representing, respectively, the “Active” and “Inactive”
status of the inputs. The status of each input is considered as one digit in the sequence, where DI1 represents
the least significant digit.
