10.8.7. Output cam programmer
This function gives a digital output (pin 8 X4) 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:
Pr140: range –2

10.8.8. Analogue output programmable
In X4 terminal block is available one analogue output programmable. The parameter Pr188
defines the parameter to monitor. The analogue output scale has a range from –512 to +512
counts corresponding ±4,096 V. By parameter Pr189 is possible to modify the scale: the value
is the exponent of base 2.
There are three different cases:
Pr188=Pr0, (monitor speed) has in escape +4,096V when Pr0=+Pr32, while –4.096V
when Pr0=-Pr32 [with Pr189=0].
