Digital Operator Control Keys
Digital Operator Control Keys
Key Label Function
LOCAL/
REMOTE
Programmable.
Typically programmed to toggle between the Digital Operator and 
Remote (terminal) modes of operation. Active only when Smart Trac 
AC1 is in stopped condition. 
JOG
Programmable.
Typically programmed to initiate Jog function while pressed and held 
in drive mode. Smart Trac AC1 output goes to programmed Jog 
Frequency to check motor operation, or to position the machine. When 
key is released, output returns to zero and motor stops. If motor is 
running, pressing this key will have no effect. May be programmed to 
be disabled if Smart Trac AC1 is programmed to use an external JOG 
input. 
FWD/REV
Programmable.
Typically programmed to toggle between motor run Forward and 
Reverse with each press of key. Selected direction is indicated by 
FWD or REV lights. If selection is made while Smart Trac AC1 is 
stopped, it determines direction motor will run when started. If 
selection is changed during running, Smart Trac AC1 will ramp motor 
to zero speed and then ramp it up to set speed in opposite (i.e. newly 
selected) direction. 
RUN
Programmable.
Typically programmed to operate by external RUN and STOP signals 
(as indicated by REMOTE SEQ lamp being lit). Pressing key will 
produce a Run command to initiate Smart Trac AC1 output to motor. 
However, output frequency will be zero if frequency reference is zero 
at time key is pressed. 
STOP
Programmable.
Typically programmed to produce a Stop command when key pressed. 
Smart Trac AC1 will decelerate motor in programmed stopping 
manner, then Smart Trac AC1 output will be disconnected from the 
motor. 
MENU
After power-up, displays top level of digital operator menu tree, 
Numeric Parameters. At the topmost level of five menus, it moves 
from menu to menu in the following order: Numeric Parameters, 
Numeric Feedbacks, Logic Parameters, Logic Feedbacks, and Special 
Functions. 
If within a submenu, returns to the topmost menu, Numeric 
Parameters. 
ESC
Returns display to previous level in menu tree or to status before 
pressing DATA/ENTER.
