UTPUT
(HLFB)
High-Level Feedback (HLFB) is the ClearPath digital output. This outp
can be wired to external devices, such as the input of a PLC,
microcontroller, or a simple LED to signal the presence of specific
Note: HLFB is not internally powered. This means it works off an
external 5–24VDC power source capable of sourcing/sinking at least 1mA
non-inductive. In typical applications power is taken from the PLC,
control board, or an external supply. See Appendix D for HLFB
specifications.

Servo On
In Servo On mode, the HLFB output asserts (conducts) when ClearPath is
enabled and not in a shutdown state. This signal can be used to monitor
ClearPath for shutdowns, or as the control signal for an external brake.
Speed Output
In Speed Output mode, ClearPath produces a 50 Hz PWM waveform
whose duty cycle is proportional to motor speed. This signal can be used

This mode is most often used to signal when ClearPath has reached
commanded velocity. In ASG-Velocity mode, the output asserts (conducts)
