- The internal potential 0V is connected to terminal 11. In the majority of the cases the interference suppres
-
sion is decreased!
- The regulation card puts at your disposal the following power supplies, which have a common reference
point:
+ 10V and - 10V for the reference
+ 24V for the power supply of the digital inputs and outputs
+ 5V for the encoder power supply
- The analog outputs are divided from the internal potential through a differential amplifier. The two outputs
of the option card have the same potential (terminal 22 and 24 of TBO option card). When the TBO option
card is used, the potential of the analog outputs are divided. For a better interference suppression and for the
“cleaning” of the output signals, the terminals 2 and 4 of the TBO option card are directly ground connected
(terminal 10 and /or 20 of the R-TPD32-EV card) or via a 0.1µF/250V capacitor.
- The digital outputs have the same potential (terminal 37) but they are divided from the regulator internal
potential via optoisolators. In order to use the outputs, it is necessary to connect a power supply voltage to
the terminal 30.
- The digital inputs are divided from the regulator through optoisolators. The terminals 31 to 34 have terminal
37 as a common potential.
External devices
As for the installation of contactors, protection devices, chokes, filters and other external devices it is neces
-
sary to follow the indication given in the previous chapters. The same theory is valid for motors, encoders and
tachometers.
Connection cables
The encoder shielded cable must be made of twisted pairs. The connection cables of the encoders and of the
motors, if possible, should be connected directly to the device, without going through support terminal strips.
The shieldings of the signal conductors have to be ground connected on both sides. Anyway, for all analog and
digital signals with very long connections (outside the electric board), it is suggested to have a ground connec
-
tion only on the converter side, in order to avoid possible noises caused by the closing of the ground loops. In
particular cases it could be necessary to connect the shielding on both sides, thus granting the point equipoten
-
tiality via suitable connection cables.
The encoder cable has to be made up of twisted loops with the global shielding connected to the ground on the
converter side. Avoid to connect the shielding on the motor side connector. In particular cases (cable longer than
100 meters, strong electromagnetic noise), it could be necessary to use a cable with a shielding on every loop to
be connected to the power supply ground. The global shielding has always to be ground connected.
