NOTE!
If some of the inputs DI4, DI5 or DI6 are set for a function different from “Multispeed”
(P0266/P0267/P0268
13), it will be considered as 0V for the selection of the reference in this
function.

Analog Inputs [32]
On the control board of the CTW900 (CC900) are two analog inputs (AI1 and AI2), normally enough for most
applications. If necessary, however, other two inputs (AI3 and AI4) can be added by means of the available
accessories

.
With those inputs, it is possible, for instance, to use an external speed reference or to control the torque current
limitation.
The following parameters present the details for these configurations.
P0018 – AI1 Value
P0019 – AI2 Value
P0020 – AI3 Value
P0021 – AI4 Value
Adjustable Range:
–100.00 to 100.00 %
Factory Setting:

Description:
Those read-only parameters indicate the value of the analog outputs AI1 to AI4 in percentage of the full scale.
The indicated values are those obtained after the offset action and multiplication by the gain.
Check the description of the parameters P0231 to P0250.
P0231 – Signal AI1 Function
P0236 – Signal AI2 Function
P0241 – Signal AI3 Function
P0246 – Signal AI4 Function
Adjustable Range:
0 = Speed Reference
Factory Setting:
0
1 = Speed Reference (N*) after the Ramp
2 = Current Auxiliary Reference (I*)
3 = Direct Torque Current Limit (I+)
4 = Reverse Torque Current Limit (I-)
5 = Direct and Reverse Torque Current Limit (I+/I-)

Description:
Those parameters define the analog input functions.
When the 0 option is selected (Speed Reference), the analog inputs can provide the reference for the motor,
subject to the specified limits (P0133 and P0134) and to the action of the ramps (P0100 to P0103). However, in
order to do so, it is also necessary to configure parameters P0221 and/or P0222 by selecting the use of the
desired analog input.
