Voltage "AO_1xV": Output ranges
- 1. Set the output range via index 0x80BD:11 "Output type".
(see table "Output ranges and scaling type") - 2. Select the scaling type via index 0x80BD:12 "Scaler":
Scaling type
0x80BD:12 | Name | Resolution 1 LSB | Meaning |
|---|---|---|---|
0x0000 (0dec) | Extended Range |
| This type of scaling allows the nominal output range to be exceeded or undershot by approx. 7 %. The technically usable range is -107 % to +107 % of the respective full scale value. For the "Extended Range", the PDO value ±30518 (0x7736) is defined as 100 % for 16 bits. |
0x0003 (3dec) | Legacy Range |
| This scaling type shows the range from -100 % to +100 %.

|---|---|---|---|
Extended Range 0x80BD:12 "Scaler" = 0x0000 (0dec) | Legacy Range 0x80BD:12 "Scaler" = 0x0003 (3dec) | Full scale value (FSV) | |
0x0002 (2dec) | -10.737 … +10.737 V | -10 … +10 V | 10 V |
0x000E (14dec) | 0 … +10.737 V | 0 … +10 V | 10 V |
The following status bits report that the output range has been exceeded:
- Underrange / Overrange: The corresponding bits are set if the output value is outside the nominal output range.
- Range Error: The error thresholds for the error bit and the error LED can be set in extended range mode via index 0x80BD:17 “Low Range Error” and index 0x80BD:18 “High Range Error”. The limit values of the technical output range are pre-set.
A complete description of these status bits can be found in the chapter Output range monitoring.
