OPT140
Optional Interface Board
The OPT140 adds such features to the IB series
drive as:
! A Removable Screw Terminal Interface.
! Isolated Current Reduction.
! 470Ω Pull-up Resistors on Logic Inputs.
! Input Capacitor.
Determining the Resistor Values
Setting the Output Current
To set the output current on the IB series drive using the OPT140 board
you will need to place R4 (See Figure A.1 below for resistor location). The
value resistor needed will match the resistor table for the model IB drive
you purchased.
