5.1 Configuration of external programmable interfaces
Some configurable inputs and outputs are available, which makes it possible to reach a
personalization level of the drive and an adequate diagnostic.
Together with the two inputs with set configuration, RE, J1/3, for torque enabling and SE,
J1/4, for the enabling of the speed reference, there are another two digital inputs: their
function can be configured through the parameters P10, IN3_CF, related to the input TE,
J1/5, and P11, IN4_CF, related to the input UE, J1/2: the meaning is shown in Table 5/1,
together with the state in which the command is active:

For alarm reset it is necessary to give a positive impulse(not a positive level) of at least 1.5
ms; on the contrary, the remaining configurations are sensitive to the level. The HW limit
switch inputs are used to generate an alarm (that can be reset only when the limit switch
signal becomes H again). There are many different possibilities for the management of such
an alarm; contact Customer Service in case of need.
For diagnostics, two digital configurable outputs and two analog configurable outputs are
available on the terminal board J1; while the former makes it possible to control the condition
of some flags of internal control, the latter give an analog representation of some internal
variables. The digital outputs are related to the terminals DIG1, J1/10 and DIG2, J1/11, with a
signal 0/+15V (for size 224 0/+24V ), in relation to ØD, not optoinsulated and with capability
of driving only a few mA. For the configuration of digital outputs see Table 5/2.

Finally, the analog configurable outputs refer to terminals DAC1, J1/21 and DAC2, J1/22,
with a signal of ±10V in relation to ØD and driving capability of 10 mA. The configuration is
