P6.21 is used to select functions of AI1, AI2, AI3 and DI terminals. Since the using methods of AI1, AI2,
AI3 and DI are identical, AI1 is described as an example here:
0: Open loop frequency or analog close loop rotation velocity reference: AI1 analog input is converted
into setup frequency via the analog curve.

5: Motor temperature feedback: It is used together with P9.17 sensor protection threshold to report
motorthermal protection alarm.
6: Reserved
Note: If the analog channel function is set to non-zero value, please make sure that different analog
channels have different functions.
In field applications, the analog values input via AI1, AI2 and AI3 terminals usually have certain
interference signals. It can enlarge the setup value of AI filter time properly to improve the
anti-interference capability of the terminal input. However, the longer the filtering time of the terminal is,
the longer the delay for the response to the action of the terminal is.
