4) Use the 'x) eXit' command. Changed values will be saved, and the Br-EFB
will exit configuration mode.
1)
Axis Enabled
This command lets you enable/disable the currently selected axis on this
Br-EFB. When an axis is disabled, the P, I and D are all temporarily set to zero
values. You will typically enable all the axis you are using, and disable the ones
that are not being used. This prevents unused axis from going into 'error' modes
and opening the relay on the 'Status' output.
2)
Proportional (P) Gain
This command lets you manually set the 'P' gain used by the currently
selected axis controlled by this Br-EFB. The 'P', or 'Positional' gain is the main
factor used in any closed loop system. It compares the position the actuator is
commanded to be positioned to with the actual measured position as sensed by
the sensor attached to the actuator. The direction and how far the desired and
actual positions are from each other controls the voltage sent to the valve
output, which sets how quickly the actuator moves towards the desired position.
The range of setting for the Proportional (P) Gain is from 0.001 to 8.000. The
default is 1.000, which gives you a One-to-One gain.
You can see this by disconnecting the valve outputs and manually positioning
your actuator (or at least the Position Feedback device) to the fully retraced
position. With the gain set to 1.000, when you send a command to the Br-EFB
for this axis to move to the 0% position, the 'valve' light will be off showing that
zero volts are being sent to the valve outputs. If you have the 'following error'
features enabled, the axis' 'Error' led for the axis will also turn off (If the board
'Error' relay output has been triggered, you may need to cycle power or the
'Valve Enable' input to reset the 'Hard Error Timeout' condition before the valve
output will be enabled). If you move either the actuator (or at least the Position
Feedback device) to the fully extended position. The valve output LED will glow
either red or green (depending on if the outputs are reversed) and 10 volts will
be sent to the valve output.
After a delay set by the 'Soft Error Timeout', the 'Error' LED for the axis will
turn on, indicating the actuator has not followed the commanded position closely
enough. After the delay set by the 'Hard Error Timeout', the output 'Status' LED
will go red, and the axis will be disabled.
