10.4.3 Value Range of output parameters
When values are to be read out, it will sometimes not be the entire range that is of inter-
est but only a restricted one. Therefore, output via the PWM output can be adapted to
the desired range by means of the 1603 / 1608 PWMOutx_ValueMin and 1604 / 1609
PWMOutx_ValueMax. As there are a great many different value ranges, these parame-
ters are to be set to the required low and high output values specified in per cent of the
value range of the respective output parameter.
Figure 10: Reading out a parameter via a PWM output
If the entire value range is required, the minimum value should be set to 0 % and the
maximum value to 100 %.
The HEINZMANN PC programme DcDesk 2000 features a special window
for PWM outputs, where the value ranges of the output parameters are
listed with their physical values and the respective percentage values are
calculated.
Parameterising Example:
Actual speed 2000 Speed is to be read out via a PWM output but the range is to be re-
stricted to 500 rpm - 1500 rpm, i.e., 500 rpm will correspond to 5 % and
1500 rpm to 95
%. As the values of this parameter have a range from 0 to 4000 rpm, the output will
have to be adapted:
