+12 Countings of backward inertia

+20 Moving countings after a 1000 mS pulse
For correct functioning, it is necessary to proceed as follows:
•
Transfer the count of the encoder connected to a remote
device (read via a serial line) in the field “Counts for encoder”
(beginning area of memory).
•
Set the count values to the desired position of the axis in the
field “Counts for setpoint positioning”.
•
Set the count values for the maximum gap of positioning in the
field “Counts for absolute maximum gap of positioning”.
•
Set the time, in decimals of seconds”, needed for the axis to
attain maximum velocity.
•
Activate the function “TunePOS” and wait that the contact
TunePOS (normally open) closes to indicate the end of the
procedure of auto-tuning the axis. At this point, the inertia data and
the reaction time of the axis are automatically memorized in the
indicated area of memory, remaining available for the function
“POS”.
•
Deactivate the function “TunePOS”.
•
Activate the function “POS”. When the axis is positioned to the
setting imposed (within the pre-established gap), the contact
79
POS (normally open) will close, to indicate the end of
positioning.
•
Activate the outputs FORWARD and BACKWARD, reading
the value of the field “Output” (VD+8). If the value of “Output”
is “1”, it is necessary to activate the output FORWARD, if it is
“-1”, it is necessary to activate the output BACKWARD, if it is
“0” it is not necessary to activate any output.
•
Set the value of the field “Output” to zero when the consent of
the function “TunePOS” or “POS” is removed, to avoid that the
output remains forced to forward or backward.
