DI6 (XDI:6) as PTC sensor input


A PTC sensor can be connected to this input for motor temperature measurement as
follows. The sensor resistance must not exceed the threshold resistance of the digital input
at the motor normal operating temperature. Do not connect both ends of the cable shield
directly to ground. Leave the other end of the shield unconnected or ground it directly via a
few nanofarads high-frequency capacitor, for example, 3.3 nF / 630 V. The shield can also
be grounded directly at both ends if they are in the same ground line with no significant
voltage drop between the end points. See the firmware manual for parameter settings.
Note: PTC sensors can alternatively be connected to FEN-xx encoder interface module.

WARNING! As the inputs pictured above are not insulated according to
IEC/EN 60664, the connection of the motor temperature sensor requires double
or reinforced insulation between motor live parts and the sensor. If the assembly
does not fulfill the requirement, the I/O board terminals must be protected against contact
and must not be connected to other equipment or the temperature sensor must be
isolated from the I/O terminals.
DIIL input (XD24:1)

The DIIL input can be selected as the source of, for example, an emergency stop
command or an external event. See the firmware manual, for more information
Drive-to-drive link (XD2D)

The drive-to-drive link is a daisy-chained RS-485 transmission line that allows basic
master/follower communication with one master drive and multiple followers.
Set termination activation jumper J3 (see section
this terminal block to the ON position on the drives at the ends of the drive-to-drive link. On
intermediate drives, set the jumper to the OFF position.
Use shielded twisted-pair cable (~100 ohm, for example, PROFIBUS-compatible cable) for
the wiring. For best immunity, high quality cable is recommended. Keep the cable as short
as possible; the maximum length of the link is 100 meters (328 ft). Avoid unnecessary
loops and running the cable near power cables (such as motor cables).
