This is ClearPath’s simplest mode of operation. Just turn on power and
ClearPath smoothly ramps to your preset velocity. Use this mode for
applications that require reliable constant velocity and a bare minimum of
wiring.
Apply main DC power and ClearPath immediately ramps up to your target
velocity (target velocity and acceleration are defined by the user during
setup). ClearPath spins at the target velocity until power is removed. All
inputs are ignored, but the output (High-Level Feedback) is functional.
Note: When power is removed, ClearPath may stop abruptly or coast a
short distance depending on the application and motor winding
configuration. Carefully test your loaded ClearPath application for
stopping behavior before deploying.

Caution! Motor shaft may spin as soon as main power is applied.
Notes: All inputs are ignored in this mode. High-Level Feedback is available.
Motor will free-wheel when main power is removed, unless external braking
force is applied. Motor may stop abruptly depending on load conditions.

Output (HLFB) - See HLFB section for available modes.
Notes:
xTo stop the motor, simply remove power and the motor will
stop.
xOther speed modes give you more control of motor behavior,
but require a little more wiring. This mode is the simplest way
to get constant, servo-controlled motion from a brushless
motor."

Torque Override Indicator
When lit,the main torque limit is being
overridden by a secondary,user-set torque
limit (e.g.,when an axis is homing, the main
torque limit may be overridden by the
separate homing torque limit setting).
