9.6.7 Output cam programmer
This function gives a digital output (OUT1) according to the present position of the motor in
a module. The user has to set the value corresponding to the module in Pr144:145. Inside the
module can be defined 2 further values (Pr146:147 and Pr148:149) indicating the position at
which the digital output is toggled. The user has to initialise the value of the motor position at
Pr142:143 and the output status at b91.1; the function is enabled by b70.3=1 and in this case
Pr142:143 shows the motor position inside the module. An offset for this position may be set
at Pr140. The refresh time of the digital output is 512 µs. The limits for the parameter values
are:
