Description / Notes
To use the bipolar option (-10 to +10) V with the version
“A2” of the control board (refer to item 2.4) the following
settings are needed:
- P234 = 2 and P236 = -50 - using AI1
- P238 = 2 and P240 = -50 - using AI2
In the option 5 in P235 or P239, the AIx can detect an
overtemperature fault (E32), through the motor PTC
detector. For this, the AIx must be configured to current
input, i. e., the DIP switch S1:3 or SI:4 must be set to
ON. The figure 6.20 shows how to make the PTC
connection to the inverter.
The two PTC inputs operate independently.

Time Constant
It configures the time constant of the analog inputs filter
between 0 (without filtering) and 200 ms.
Thus the analog input will have a response time equal to
three time constants. For instance, if the time constant is
200 ms, and a step is applied to the analog input, the
response will be stabilized after 600 ms.
