65 FEEDBACK SOURCE
Screen 65 FB SRC=O/LOOP
Description FEEDBACK SOURCE
FUNCTION Selects a feedback source (from the following
list) to provide the Microdrive with S-curve
acceleration control or as a simple closed loop
process controller.
CODE FEEDBACK SOURCE
O/LOOP INTERNAL S-RAMP
010V ANALOGUE - 010Vdc
420mA ANALOGUE - 420mA
TACHO PULSE TACHO INPUT (TACHO FEEDBACK)
The feedback time constant (Screen 17) is
used to set the time response of the feedback
system and the S-curve rate.
SETTING UP If an external feedback source is not required,
set to open loop ([O]pen [LOOP]) which enables
the S-curve function.
Select the desired feedback source for your
application.
Use the feedback time constant (Screen 17)
to set the time response.
Use the feedback sense relay hysteresis
(Screen 54) to monitor the feedback status.
For obvious reasons, do not select the
reference and feedback from the same source.
Examples of the use of feedback are given in
the appendices.
