In this program mode the angles at which the 32 outputs switch on and off can be programmed
and viewed. The mode window will display the letter
“P”
on left to indicate that program mode
has been entered.
The
BATCH
display will show the currently selected BATCH NUMBER.
Select the batch to be programmed as outlined above.
On entering the program mode the cam number will be set to 1 with
window A showing the angle at which the output of cam 1 comes ON
window B showing the angle at which the output of cam 1 comes OFF
Window A will be flashing to indicate that the On angle can be changed if necessary.
If the window displays CCC then there is no programmed data for the output being viewed.
Enter a value using the number keys on the keypad or else use the JOG keys.
Values larger than 359 degrees will not be accepted and the display will default to zero awaiting
re-entry of correct data.
Thus to enter an ON angle of 54 proceed as follows,
After pressing ENTER the data in window A will stop flashing and window B will start flashing.
The OFF angle can now be entered. If an OFF angle of 89 degrees is required then proceed as
follows,
When the
ENTER
key is pressed with the B window flashing the CAM NO display will increment
by one and window A will start flashing again. At this point the data for cam 1 is valid
An OFF angle of 360 can be entered (see below).
Note:
If both A and B angles are programmed to the same value then the output will stay off.
If a cam output is required to be On at all angles then enter the OFF angle as 360 degrees. In this
case the On angle is ignored. A value of 360 degrees cannot be entered using the JOG keys.
Cams 2 to 32 can be programmed in exactly the same manner. In the limited program mode only
cam numbers up to the value set on parameter page 4 can be programmed in this way.
To examine the programmed angles of any of the cam outputs, say CAM NO 4, the following
sequence can be used,
Display A and B will now show the programmed angles for cam number 4.
However if there are some outputs which have not been programmed (CCC) and one of these is
selected using the above key sequence then the unit will select the lowest output which is
unprogrammed.
For example if cams 1 to 12 have been programmed and an attempt is made to select cam
number 16 cam 13 will be automatically selected since this is the next cam that can be
programmed.
Pressing the
ENTER
key continuously allows the operator to scan through all of the programmed
values.
Programming
can
be carried out whilst the machine is running, this enables fine tuning of a
process. When operating in this manner, great care must be taken not to enter values which could
cause damage to the machine. It is therefore recommended that this facility only be used when
absolutely necessary.
