7.4.3. The speed adjustment
If you selected the menu "
Speed
" in the system setting
menu, the speed adjustment menu appears on the
display:
You can use it to optimally adjust the speed of the device
to the speed of the gear.
7.4.3.1. The speed factor
Normally the speed is displayed through the number of
increments or impulses per second, an output of the
measuring system. If you want the speed displayed e.g. in
rotations per minute or in the number of pieces per
minute, you have to enter a randomizing factor.
Example 1:
A rotation encoder with 512 steps supplies 512 increments per minute, which means
that the gear runs with 1 rotation per minute. The CamCon measures 512/60 = 8,533
increments per second.
To receive a display in rotations per minute enter the factor 1/8,533 = 0,1172.
Example 2:
A rotation encoder with 360 steps supplies 360 increments per minute, which means
that the gear runs with 1 rotation per minute. The CamCon measures 360/60 = 6
increments per second.
Enter a factor of 1/6 = 0,16666 to have the display remain in rotations per second.
Note:
The speed factor is influenced by inputs in an electronic gear. Also see chapter "7.4.1.4.
The electronic gear" on page 46.
7.4.3.2. The display format of the speed display
When you have adjusted the speed range with the factor, you can enter the presentation format of the
display, using the
and
keys (see chapter "5.4. Text input" on page 26).
The # symbols are place holders for the displayed value. If
e.g. the highest value is lower than 1000 and only has
three digits, you only enter three # symbols. If you want a
decimal point displayed, just insert it between the symbols
(e.g. : ###.##). Press the
key, and the curser moves to
the next menu point.
7.4.3.3. Range adjustment of the speed display
In this menu point you enter the maximum speed of your gear or the speed of your movement. This
input is used to adjust the speed display.
An input of e.g. 1000 rotations per minute means that at
+/-1000 rotations per minute the maximum analog output
voltage, (100%) +/-10V, is reached.
This scale also applies to the speed bar that is shown in
the middle of the standard display. Its length is the current
speed compared to the entered reference speed in
percent. Furthermore this is the point of the speed where
the standard display switches from the position to the
current speed. This point always lies at 5% of the here
entered value, for 1000 rotations per minute it lies at 50 rotations per minute.
