Digital Outputs
The combined I/O board provides two user-configurable digital outputs, using
connector positions designated DO1 and DO2. These two digital outputs are
configured using inverter parameters Digital Out1 Sel through Digital Out2
OffTime (380...387).
The combined I/O board contains six special purpose digital outputs, using
connector positions designated DO3...DO8. The state of these six outputs can be
changed by writing to inverter parameter Appl Digital Out (30).
All eight digital output devices are form C relays capable of switching 250V AC
at 8 A, or 30V DC at 8 A.
The combined I/O board also contains dedicated terminals for driving the shunt
trip circuit.
Analog Inputs
The combined I/O board provides two user-configurable analog inputs.
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 combined I/O board terminals that
should be used.
