ASG-Velocity Latched works in the same way as ASG-Velocity except that
the HLFB output latches once asserted (conducting). The output remains
asserted until the motor is disabled, goes into a shutdown, or receives a
new velocity command.
Even if the motor is momentarily pushed out-of-range when being
commanded to move at constant velocity, the HLFB will remain asserted
(conducting).

ASG-Velocity with Measured Torque works in the same way as ASG-
Velocity except, during commanded acceleration and deceleration the
HLFB outputs a 45 Hz or 482 Hz (user selectable) PWM waveform that
varies in duty cycle between 5% and 95% to indicate direction and
magnitude of motor shaft torque as follows:
•
5% duty cycle = 100% peak torque, CW direction
•
50% duty cycle = zero torque
•
95% duty cycle = 100% peak torque CCW direction.

ASG-Velocity Latched with Measured Torque is a combination of all the
previous ASG-Velocity modes. During commanded acceleration the HLFB
outputs a PWM waveform to indicate motor shaft torque. Once the motor
reaches "At Target Velocity", the HLFB output latches on (Conducting)
even if the motor is momentarily pushed "Out-of-Range" until the motor
is disabled, goes into a shutdown, or receives a new velocity command.

ELOCITY
During operation, HLFB asserts (conducts) when the motor is enabled,
not shutdown, and the actual velocity is "In-Range" (
±
X%) of the
commanded velocity. The "In-Range" window X, can be set through the
MSP software.
