SV Manipulated variable
Value range: 0 to 4095 (12 bit) of this value
range corresponds to 0...100% of the period dur-
ation. Notes on the normalization of the manip-
ulated variable are provided in the previous
section Manipulated variable SV.
No signals are output at Q1 and Q2 if
SV=0 or SV<ME, and the output con-
cerned will stay at 0.
PD Period duration [ms]
When the value is 0, no pulses are output at
Q1 and Q2.
The minimum period duration for a device with
transistor outputs is 5 ms.
(the resulting max. frequency is 200 Hz).
Value range: 0…65535
ME Minimum On duration [ms]
The minimum on duration for devices with tran-
sistor outputs is 0.1 ms.
This on duration applies if ME is not set or set
to 0.
If ME=1, the on duration is 1ms etc..
The minimum on duration possible essentially
depends on the downstream electronics.
Value range: 0…65535
Manipulated variable SV
The value range from 0 to 4095 of the manipulated variable SV corresponds to 0 to
100% of the period duration.
If you wish to control the pulse duration with the DC.. PID controller, you can associate
the DC..QV output directly with the input PW..SV. This kind of application does not
require any normalization since the DC..QV covers the same value range between 0 and
4095.
If you wish to control the pulse duration via an analog input that has a value range
between 0 and 1023, you will have to normalize this value first of all. If you require an
integral normalization factor, in this case the factor of 4, only multiplication with the AR
arithmetic function block is required.
