Function:
The analogue output can be used for stating a process
value. It is possible to choose two types of output sig-
nals 0 - 20 mA or 4 - 20 mA.
If used as a voltage output (0 - 10 V), a pull-down re-
sistor of 500
Ω
must be fitted to common (terminal 55).
If the output is used as a current output the resulting
resistance from the equipment connected may not ex-
ceed 500
Ω .
Description of choice:
No function . Is selected if the analogue output is not to
be used.
External Ref
MIN
- Ref
MAX
0-20 mA/4-20 mA.
An output signal is obtained, which is proportional to
the resulting reference value in the interval Minimum
reference, Ref
MIN
- Maximum reference, Ref
MAX
(pa-
rameters 204/205).
FB
MIN
-FB
MAX
0-20 mA/ 4-20 mA.
An output signal is obtained, which is proportional to
the feedback value in the interval Minimum feedback,
FB
MIN
- Maximum feedback, FB
MAX
(parameter
414/415).
0-f
MAX
0-20 mA/4-20 mA.
An output signal is obtained, which is proportional to
the output frequency in the interval 0 - f
MAX
(parameter
202 Output frequency, high limit, f
MAX
).
0 - I
INV
0-20 mA/4-20 mA.
An output signal is obtained, which is proportional to
the output current in the interval 0 - I
INV
0 - P
M,N
0-20 mA/4-20 mA.
An output signal is obtained, which is proportional to
the present output power. 20 mA corresponds to the
value set in parameter 102 Motor power, P
M,N
.
0 - Temp.
MAX
0-20 mA/4-20 mA.
An output signal is obtained, which is proportional to
the present heatsink temperature. 0/4 mA corre-
sponds to a heatsink temperature of less than 20 °C,
and 20 mA corresponds to 100 °C.
