APPENDIX A – OPTIONAL IODA INPUT/OUTPUT MULTI-FUNCTION BOARD
For detailed operation of the IODA, see the IODA Installation and Operation Instruction Manual (Part No.
A40159).
The IODA Input/Output Multi-Function Board provides a variety of functions which include preset frequency,
up/down frequency control, signal isolation, isolated output voltage for controlling auxiliary devices, output relay
contacts, and open collector outputs. The IODA mounts on the drive's PC board with 3 screws (provided). All of the
IODA inputs and outputs are isolated from the AC line.
The IODA has a green LED for power (PWR) and a red LED for (STATUS). These LEDs are used to provide
operational information of the IODA. See Table 9, on page 31, for a description of the Status LED. See Figure 20,
on page 31, for the IODA layout. See Table 10, on page 31, for the IODA Terminal Block TB1 Wire and Tightening
Torque Specifications. See Figure 21, on page 32, for the IODA Terminal Block TB1 Layout. See Table 11, on
page 32, for the IODA Functions, Features, and Terminal Assignment. See Appendix Sections A1 – A7, on pages
33 – 39, describing Using of the IODA Multi-Function Input Terminals for Remote Operations. See Appendix
Sections A8 – A12, on pages 40 – 49, for Other Functions and Features of the IODA.
Local/Remote Operation: When using the IODA with signal following, it will be necessary to program the drive for
Local/Remote Operation. In this mode, the drive frequency setting can be toggled between a process signal and the
keypad using the JOG-LCL/REM Key. Set Jog-Local/Remote (Function No. 2.02) to Jog Disabled; Local/Remote
Enabled ("0002") to change the JOG-LCL/REM Key from Jog Operation to Local/Remote Operation.
IODA Faults: External Fault Trip ("EF–t") indicates that a Multi-Function Input Terminal (Function Nos. 7.00 – 7.06
set to "0008") has closed (and will change the state of the Multi-Function Output Relay Contacts and the Multi-
Function Open Collectors (when Function No. 8.00 to 8.03 is set to "0007")). Current Source Trip ("CS–t") indicates
that the current signal output (from the IODA) has been opened. Communication Error ("Err4") indicates that
communication between the drive and the IODA has failed.
WARNING! Do not depend on the Status LEDs or the 4-Digit Display to no longer be illuminated as a
guaranteed power off condition. Be sure the main power switch or circuit breaker is in the "OFF" position
before servicing the drive.
STANDARD FEATURES
▪ Signal Input Isolation: Provides isolation between signal sources and the drive.
▪ Potentiometer Operation: A remote 5 kΩ potentiometer can be used in lieu of the Keypad or the Built-In
Potentiometer. The remote potentiometer can be connected for forward, reverse, or bidirectional motor speed
control.
▪ Multi-Function Input Terminals: Used for a variety of functions, which include Preset Frequency; Up/Down
Frequency Command; Forward/Stop and Reverse/Stop Command; External Fault; Reset; 2-Wire and 3-Wire
Start/Stop.
▪ Multi-Function Output Relays: Two Multi-Function Output Relays are provided, which can be programmed for
Run, Fault, Target Frequency, Frequency Threshold Level, I 2 t or I•t Fault, Load Loss, External Fault, and Motor
Overload.
▪ Multi-Function Open Collector Outputs: Two Multi-Function Output Relays are provided, which can be
programmed for Run, Fault, Target Frequency, Frequency Threshold Level, I 2 t or I•t Fault, Load Loss, External
Fault, and Motor Overload.
▪ Isolated Signal Output: Two isolated analog signal outputs are provided, which can be used to monitor Motor
Frequency, Set Frequency, Motor Voltage Bus Voltage, and Motor Current. Analog Output 1 provides a 0 – 5 Volt
DC signal output. Analog Output 2 can be programmed for 0 – 5 Volt DC, 4 – 20 mA DC, or 0 – 20 mA DC.
▪ Selectable Jumpers: For voltage or current signal selection.
▪ Multi-Turn Trimpots: For fine adjustment and attenuation of signal inputs.
▪ LEDs: The green power on LED (PWR) indicates that power is applied to the IODA from the drive. The red status
LED (STATUS) provides indication of the IODA operation.
▪ Barrier Terminal: All connections to the IODA are made via the barrier terminal block. All terminal block
connections of the IODA are isolated from the AC line.
▪ Easy Installation: Uses 3 screws (provided) for mounting and a ribbon cable for wiring to the drive.
