Mode Diagram Overview
Input
Description
Multi-Function Inputs
The active function of each
input is shown next to the
external switches in the Mode
diagrams� Example: In
Analog
0-5V
Speed Mode
, the inputs’
functions are
Run
,
Direction
,
-Limit
, and
Disable
�
Run/Stop Inputs
The
Run/Stop
function (in
analog modes) uses accel
and decel ramps to transition
speed�
Limits Inputs
The Limit inputs are direction-
sensitive and are Normally
Open (they allow motion if
left unconnected)� The Limit
function uses decel and accel
ramps� Note that only the
-Limit
is available in
Analog
0-5V Speed Mode
�
Enable/Disable Inputs
This input is often left
unconnected� The
Disable
input does not use a decel
ramp (stops quickly), but does
use an accel ramp to restart�
Once the drive is disabled, the
Run
input should be removed
before the drive is re-enabled�
Otherwise, the drive
may
lose
synchronization with the motor
on restart (if accel or set speed
is high)�
