Analog Outputs Continued
Example 1 – Read the field current feedback using Analog Output 1.
The tag number for the field current feedback parameter is 300.
1. Set CONFIGURE I/O::CONFIGURE ENABLE to Enable.
2. Set ANALOG OUTPUTS::ANOUT 1 (A7):: SOURCE TAG to 300.
3. Set ANALOG OUTPUTS::ANOUT 1 (A7):: % TO GET 10 VDC to 100% (factory setting).
4. Set SETUP PARAMETERS::CALIBRATION::ARMATURE I (A9) to Bipolar (factory setting).
5. Reset CONFIGURE I/O::CONFIGURE ENABLE to Disable.

Example 2 – Connect the serial link to Analog Output 1.
Allows analog output 1 to read values written by an external device to PNO 58 (ASCII 3A) which is AUX I/O
Analog Out 1. The tag number for the AUX I/O::ANOUT 1 parameter is 128.
1. Set CONFIGURE I/O::CONFIGURE ENABLE to Enable.
2. Set ANALOG OUTPUTS::ANOUT 1 (A7):: SOURCE TAG to 128.
3. Set ANALOG OUTPUTS::ANOUT 1 (A7):: % TO GET 10V to 100% (factory setting).
4. Reset CONFIGURE I/O::CONFIGURE ENABLE to Disable.

Example 3 – Connect the current demand to Analog Output 2.
The tag number for the current demand parameter is 66.
1. Set CONFIGURE I/O::CONFIGURE ENABLE to Enable.
2. Set ANALOG OUTPUTS::ANOUT 2 (A8):: SOURCE TAG to 66.
3. Set ANALOG OUTPUTS::ANOUT 2 (A8):: % TO GET 10V to 200%.
4. Reset CONFIGURE I/O::CONFIGURE ENABLE to Disable.
Setting % TO GET 10V at 200% results in 5 volts output when current feedback is at 100%.
