Valve parameter settings in application
The parameters must be configured correctly before operating the valves. Check
the parameters according to the datasheets of the valves. See the SAPRO help
document for more details.
Parameters Object member name Usage Notes
Drv1/2 Speed 1:Speed Valve move speed setting;
Refer the Halfstep mode
setting
2:Speed
Drv1/2 OverdriveClose 1:OverdriveClose
Use for the Valve define the
reference position at the initial
phase, Valve will close
additionally steps of normal
TraversePath plus
OverdriveClose setting
Recommend to use 30% of
travel path.
2:OverdriveClose
Drv1/2 OverdriveOpen 1:OverdriveOpen
Use for the Valve define the
reference position at the initial
phase. Valve will open
additionally steps of normal
TraversePath plus
OverdriveOpen setting
Recommend to use 30% of
travel path.
2:OverdriveOpen
Drv1/2 Traverse Path 1:TraversePath
TraversePath is the number of
steps needed to move from
fully closed to fully open. The
setpoint position must be
remained within the defined
range.
Refer the Halfstep mode
setting
2:TraversePath
Drv1/2 DeadTimeSync 1:DeadTimeSync
The number of minutes after
the last reference that a new
automatic reference path is
forced.
2:DeadTimeSync
Drv1/2 HalfStep 1:HalfStepMode Defines the stepper mode.
In case of Half Step mode the
amount of steps (like traverse
Path, speed and so on) must
be double of the Full Step
mode. One consequence is,
that the motor speed is half
(max. 250 1/s) of the full step
mode (max 500 1/s).
Recommend use half step for
control precious, use full step
for reaction speed
2:HalfStepMode
Drv1DelayDirection 1:DelayDirection
Defines the minimal wait time
in ms before the direction is
changed.
2:DelayDirection
Drv1HoldCurrentFactor 1:HoldCurrentFactor
Defines the current factor to
hold the position as the
commanded position is
reached.
The value of 10 equals 100%
off time. The motor is
completely powerless.
2:HoldCurrentFactor
