Standard I/O Board
Description (Frame 3 Only) The Standard I/O board is offered as an option for Frame 3 LiquiFlo 2.0 drives.
The following signals are available at the Standard I/O board. The Standard I/O
board is labeled as item 24 in
Figure 4 . See Figure 10 for terminal identification.
Digital Inputs
The Standard I/O board terminal block provides terminals (27...32) for six
user-configurable digital inputs. These inputs can be configured using the
inverter digital input selection parameters (361...366).
Digital Outputs
The Standard I/O board terminal block provides terminals for two
user-configurable digital outputs (terminals 11...16). These logic outputs can be
configured for any of the 30 functions controlled by Digital Out1 Sel (380) and
Digital Out2 Sel (384).
The digital output devices are form C relays capable of switching 250V AC at 8 A
or 30V DC at 8 A.
Analog Inputs
The standard I/O board terminal block provides two user-configurable terminals
for analog inputs (terminals 1...4 and 17...20). Configure the inputs using inverter
parameters Anlg In Config through Analog In 2 Loss (320...327). Each analog
input has two modes: voltage-sensing (input senses -10 V...10 V) and current-
sensing (input senses 0 mA...20 mA). Separate terminals on the standard I/O
board are used for each mode.
The mode for both inputs are selected via inverter parameter Anlg In Config
(320). If the bit corresponding to a particular analog input is set to 1, then the
analog input is in current-sensing mode; if set to 0 it is in voltage-sensing mode.
The following table describes the correspondence between the mode of each
user-configurable analog input and the standardI/O board terminals that should
be used.
