Analog/digital outputs
The two analog/digital outputs (terminals 42 and
45) can be programmed to show the present status
or a process value such as 0 - f
MAX
.
If the VLT AFD is used as a digital output, it gives
the present status by means of 0 or 24 V DC. If the
analoge output is used for giving a process value,
there is a choice of three types of output signals:
0-20 mA, 4-20 mA or 0-32000 pulses
(depending on the value set in parameter 322
Terminal
45, output, pulse scaling
. If the output is used as
a voltage output (0-10 V), a pull-down resistor of
470
(max. 500
) should be fitted to terminal 39
(common for analog/digital outputs). If the output is
used as a current output, the resulting impedance of
the connected equipment should not exceed 500
.
Outputs
