4th field
: consents the use of the second display line by suppressing the automatic val-
ue display. When set at 0 the value is displayed, when set at 1 the area may be used
to send text via CAN BUS.
5th field:
Set at 1, this field forces transmission of ID 701h even in the presences of a movement
control and movement actuation.
The above details refer to standard firmware installed on the board for the STEPPING-
MOTOR VERSION.
Controls
:
After having connected the external devices to the board and, set up stepping-motor
voltage by means of trimmer R8, the board needs to be tested for CAN BUS net inter-
rogation response.
The standard versions frame 701h, composed of 5 bytes, is sent automatically every
250 msec.
Receipt of this frame indicates correct CAN BUS net connection.
We start by sending
ID=700h DLC 8
; the board should reply with a string correspond-
ing to the model.
We can then transmit control ID=703h DLC 8 to obtain the board serial number when-
ever necessary.
Frame 704h DLC = 5 is transmitted with the appropriate values bearing in mind that, if
we want the board to consider the 4 parameters, the mask (1st byte) to be sent will be
0Fh.
This frame is not normally sent again
Frame 705h DLC =7 is then sent with values related to the two speeds (frequency)
and acceleration time.
In this case also, the mask byte (07h) must be supplied.
Supposing we want a start frequency of 200 Hz and a running frequency of 1000Hz,
acceleration time between the two frequencies of 300 mSec, we would send the follow-
ing string: (besides ID e DLC) 07h 00h c8h 03h E8h 01h 2Ch.
We might want to perform a movement at a different running speed for some particular
reason, eg.: running= 1500Hz. The string would be 02h 00h 00h 05h DCh 00h 00h.
The underlined digits can contain any value since, because of the mask 1st byte, they
are not considered.
The same consideration applies to the variation of one or more parameters.
The correct procedure is now to send a re-set control to the motorised axis. To do this
we send the following frame:
702h DLC = 1 with the 1° byte (type of movement) = 00h
Wait for the re-setting cycle to terminate
