The controller's DOUTs are represented by a mask of bits, to be used with the STI command. The number of
digital outputs is different from a position controller to another. Here is a table giving the number of digital
outputs present on each position controller (refer to the corresponding
’Hardware Manual’
for more
information):
Caution:
On the DSCDM, the digital inputs and outputs are on the same pin. The pin must be selected in
order to have an input
or
an output.
It is NOT possible to have both on the same pin.
The state
of the digital output is given by the value of parameter K171.
Example:
K162.1 = 15
;15=(1+2+4+8) means that all the DOUTs of the controller will be modified when a
STI command is executed.
K163.1 = 2
;the status will be DOUT2=1 (bit# 1, value 2), and all the other DOUTs = 0.
Parameter
K164
: time limit for STI start
The ISO time is for the DSC2P/DSC2V: K164 x 166.67
µ
s. Thus, K164 max. value = 100[sec].
DSCDP, DSCDL and DSCDM: K164 x 500
µ
s. Thus, K164 max. value = 300[sec].
STI command timing
STI use example:
The user wants the movement to begin when DIN1=0 and DIN10=1.
Furthermore, the user wants DOUT2 to move to 1 and DOUT1 to 0 when the movement begins.
K160.1 = 513
;513 = (1 + 512) means that the inputs DIN1(=1, bit# 0) and DIN10 (= 512, bit# 9) will
be tested to execute a STI command

STI time-out limit
Defines the time limit between the moment when the STI command is sent and the moment when
the DIN (defined in mask K160) are set to the required values (defined in mask K161). If this time is
exceeded, a
SYNCHRO START
error (M64=63) appears on the controller.
