9. SETTING PARAMETERS
The parameter mode can only be accessed at power with the 2 keys held down,
The message
1.con
will appear indicating that in the A display the parameters for page 1 are being
displayed..
PARAMETER PAGE 1
This page sets the encoder type, the count direction and display resolution.
It should be set according to the encoder selected ,
A
Absolute - 1 degree resolution
The sign indicates the count direction. Note that no sign is indicated for clockwise rotation (the + sign is
assumed). To change the sign press the UP arrow key, (the display will flash) and then press the
decimal point key. The sign will change. Press the UP arrow key once more to stop the flashing.
To exit this parameter page press the
ENTER
key with A deselected. This will take you to page 3 of the
parameter mode.
PARAMETER PAGE 2
This page is not available on absolute cam units.
PARAMETER PAGE 3
This page allows the user to set a minimum rotational speed for the cam which must be exceeded for
the unit to operate. This can be used to ensure that the encoder is rotating. The creep speed value can
be entered by selecting the parameter (UP arrow) entering the value using the numeric keys and then
deselecting the parameter (use the UP arrow once more). A value of 0 disables this test. The switching
accuracy of this test is ~10%
The value entered is the minimum
(number of encoder counts per sec / 5 )
that must be received by
the electronic cam.
•
If the number of counts fall below this value and n has been set on parameter page 10, then if the
unit is in RUN it will switch itself out of RUN and generate an ERROR 2 signal.
This error code can be reset by pressing any key.
•
If however F has been set on parameter page 10 then output 16 is used to indicate the state of the
creep speed test. If the number of counts received is above that programmed on this page then
output 16 will be ON. If the counts fall below the programmed value then output 16 will be OFF. The
unit does NOT drop out of run mode.
Example:
output 16 is to trip off at 300 rpm.
No revs/ sec = 5; no of degrees/sec = 5 * 360
no of degrees in 1/5 sec = 5 * 360 / 5 = 360 - this is the creep speed value required.
To exit from page 3 to page 4 press the
ENTER
key with the A display not flashing (not selected).
PARAMETER PAGE 4
This page allows the user to prohibit programming of certain cam outputs. This feature can only be used
in conjunction with the External Partial Inhibit line. If this line is active then no cam outputs above the
configured value can be altered. To change this value set select the A display by pressing the UP arrow
key and press
ENTER
. This will increment the number displayed by 1 up to the maximum value of 32. If
the value is 32 then the next press of enter will reset the value to 1.
To exit from page 4 to page 5 press the
ENTER
key with the A display not flashing (not selected).
