Mode Diagram Overview
Description
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�
The Run/Stop function (in
analog modes) uses accel
and decel ramps to transition
speed�
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�
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)�
