(HLFB)
ClearPath has one, user settable, multi-purpose, digital output called the
HLFB Output (HLFB stands for "High-Level Feedback"). The HLFB
output conveys motor and motion-related feedback to your PLC,
microprocessor, or other control device.
The HLFB configuration dialog is accessed from the Advanced menu as
shown below.
Advanced>High-Level Feedback
.
HLFB output can be used to signal:
•
If the servo drive is enabled or in a shutdown (Servo On mode).
•
When the commanded move is complete and settled to the user's
specifications (ASG-Position mode).
•
How well the motor is following your positioning or velocity
commands (In Range).
•
Motor speed, via PWM output (Speed Output mode).
•
Motor position, via PPR output (Pulses Per Revolution).
•
Motor torque, via PWM output (Torque Output mode).
Note:
The
HLFB circuit is not internally powered; it requires an external
5–24VDC power supply capable of sourcing/sinking at least 1mA, non-
inductive. In typical HLFB applications, power is supplied by the PLC,
control board, or an external supply. See Appendix D for complete HLFB
specifications.
