AXIS HOME TO INDEX PULSE - Causes the actuator to
move until it detects the home switch then an index pulse. The
home to index pulse routine works by moving in the selected
direction until it detects the home switch, it then decelerates to a
stop and moves at the creep speed in the opposite direction unit
it detects the first index pulse after a transition in the home
switch. There is an option to allow an automatic reversal of
direction if the end of travel is encountered before the home
switch.
DEFINE PRESENT POSITION – Allows either Actual or
Commanded position to be arbitrarily defined as an absolute
position.
Note: All future absolute positions will be referenced against this
definition.
SET COMMAND POSITION TO ACTUAL – This command
sets the Commanded position (from the trajectory generator) to
match the Actual position (as determined by encoder feedback).
As a result, following error is zeroed out.
ABSOLUTE POSITION FEEDBACK, ANALOG – This
sequential instruction allows switching position feedback for
servo control from the incremental encoder to an absolute,
analog source. This "Absolute Position Feedback from Analog
Input" instruction can be accessed in the sequential
programming editor as a "homing" type instruction.
When this instruction is executed, the axis position is essentially
referenced to an absolute position based on the analog input
value and the user entered instruction parameters. Indexer
status flag 004 is set upon successful execution of this instruction,
as the axis is then effectively "homed". Subsequent motion
commands will than servo based on the analog input value.
ANALOG POSITION CONVERSION FACTOR
The parameter "Analog Position Conversion Factor" allows the
user to set a scale factor relating user units of position to volts of
absolute feedback. This value can be positive or negative.
NOTE: It is important that the sequential program encoder
