AIx' = -30.0 % means that the motor will spin counterclockwise with a reference in module equal to 30.0 % of
P0134 if the signal AIx function is "Speed Reference".
In the case of filter parameters (P0235, P0240 and P0245), the value set corresponds to the time constant used to
filter the input signal read. Therefore, the filter response time is around three times the value of this time constant.

12.2 ANALOG OUTPUTS

The analog outputs (AOx) are configured by means of three types of parameters: function, gain and signal, as per
block diagram of
The standard CFW500-IOS plug-in module has just the analog output AO1, but the CFW500-IOAD plug-in provides
one more analog output AO2.

Description:
Those read-only parameters indicate the value of the analog outputs AO1 and AO2 in percentage of the full
scale. The indicated values are those obtained after the multiplication by the gain. Check the description of
parameters P0251 to P0256.
