APPENDIX A – OPTIONAL IODA INPUT/OUTPUT MULTI-FUNCTION BOARD
The IODA Input/Output Multi-Function Board provides a variety of functions, which include preset frequen-
cy, up/down frequency control, signal isolation, isolated output voltage for controlling auxiliary devices,
open collector outputs, and output relay contacts. The IODA mounts on the drive’s PC board with 2 snap-
ins (located on the bottom of the mounting base) and 2 screws (provided). All of the IODA inputs and out-
puts are isolated from the AC line.
The IODA has a green power on LED (PWR) and a red status LED (STATUS), which are used to provide
operational information of the IODA. See Table 10, below, for a description of the IODA status indicator
LED. See Figure 24, on page 43, for the IODA layout. See Figure 25, on page 43, for the IODA Terminal
Block TB1 Layout. See Table 11, on page 43, for the IODA Terminal Block TB1 Wire and Tightening Torque
Specifications. See Table 12, on page 44, for the IODA Functions and Features. See Sections A1 – A7, on
pages 45 – 49 describing the use of the IODA Multi-Function Input Terminals for Remote Operations. See
Sections A8 – A12, on pages 49 – 54, for Other Functions and Features of the IODA.
Local/Remote Operation – When using the IODA with signal following, it may be appropriate 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 Nos. 8.00 – 8.03 are 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 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.
TABLE 10 – IODA STATUS INDICATOR LED
Condition Red STATUS LED
Normal Operation Not Illuminated
Communication Error 1 Flashes 1 Second On and 1 Second Off
Current Source Trip 2 Illuminated
Notes: 1. When a Communication Error occurs, the drive’s 4-Digit Display will show “Err4”. 2. When a Current Source
Trip occurs, the drive’s 4-Digit Display will show “CS-t”.
