Analog outputs (AO’s)
The basic I/O board is the SDCS-CON-F with 3 standard AO’s. Two AO’s are programmable, the third one is
fixed and used to display the actual armature current taken directly from the burden resistors. They can be
extended by means of one RAIO-01 analog I/O extension module. Thus, the maximum number of AO’s is 5.
The hardware source is selected by:
−
AIO ExtModule (98.06) for AO3 and AO4
SDCS-CON-F
Output range AO1 and AO2 set by parameter:
−
±
10 V, 0 V to 10 V, 2 V to 10 V, 5 V offset, 6 V offset
Output range fixed AO I-act:
−
8 V equals the minimum of 325 % M1NomCur (99.03) or 230 % ConvNomCur (4.05) see also IactScaling
(4.26)
Resolution:
−
11 bits + sign
Cycle time for AO1 and AO2:
−
5 ms
Cycle time fixed AO I-act:
−
directly taken from hardware
RAIO-01
Output range AO3 and AO4 set by parameter:
−
0 mA to 20 mA, 4 mA to 20 mA, 10 mA offset, 12 mA offset
Resolution:
−
12 bits
Cycle time for AO3 and AO4:
−
5 ms
Additional functions:
−
all AO’s are galvanically isolated
Configuration
The value of AO1 and AO2 can be read from group 5.

The AO’s can be connected to any integer or signed integer of the drive by means of group 15. It is
possible to invert the AO’s by simply negate IndexAO1 (15.01) to IndexAO4 (15.16).
