4.5.8. General purpose analog input¶
Analog input may be used for other purpose. For example, it can be used to measure any external signal. Value at the analog input may be read by the GETC command and is visible in the XiLab charts.
This controller represents analog input values as a number in 0..10000 range. Analog input pin is located on BPC connector.
IMPORTANT. Analog input voltage should not go outside of 0-3 V range. If this voltage is exceeded errors in analog input and other controller subsystems are possible! This may also damage the controller or connected motor.
| Signal voltage | 0-3 V |
| Scanning frequency | 1 kHz |

Controller board¶
For the controller board analog input contact is located on the BPC connector.

One-axis and two-axis systems¶
Only two-axis system has general purpose analog input on supplementary HDB-26 connector.

Multi-axis system¶
Multi-axis system does not have general purpose analog input.
