Parameter
Description
P6.21 is used to select functions of AI1, AI2 terminals. Since the using methods of AI1and AI2 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.
1~4: Reserved
5: Motor temperature feedback: It is used together with P9.17 sensor protection threshold to report motor
thermal protection alarm.
6: Reserved
Note: If the analog channel function is set to a non
−
zero value, please make sure that different analog
channels have different functions.
In field applications, the analog values input via AI1, AI2 usually have certain interference signals. It can
amplify 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.

function Output Parameter (Group P7)
Y1 and relay terminals can be defined as multifunctional digital signal output. AO1 and AO2 terminals
can be defined as multifunctional analog value output, and the analog value type (0 ~ 10V/0 ~ 20mA) can
be selected via the jumper.
The definition table of multifunctional digital signal output is as follows:
