Terminating resistor
After connecting the modules, make sure that the elements at each
end connected to the bus have the terminating resistor activated; i.e.
the terminal resistor switch (under the CAN connector) of the last
drive (usually the one farthest away from the CNC) is set to 1 (switch
down) and the rest of the drives with the terminal resistor set to 0
(switch up).The CNC (or the ESA panel), located at the end of the bus
always has this resistor activated.

ELECTRICAL INSTALLATION
MOUNTING CONDITIONS
The servodrive system must be mounted vertically in the
electrical cabinet with the power connectors on top.
The equipment should be installed so as to leave at least 80 mm
(3.15 in) above and below it.
The temperature around the equipment should always be under
55°C/131°F. Vibration should be avoided.
When applying external cooling to the system, make sure that
water condensation does not fall on the equipment.
Never install the servodrive system in places where there are
corrosive gases.
The ER+TH-x/x and ER+TH-18/x+FAN modules should be
mounted away from the rest of the heat sensitive modules and
materials. We recommend the upright position with the cables
down (ideal case), but the horizontal position is also acceptable
(although with lower dissipation). Never position it in the upright
with the cables up.
ELECTRICAL INTERCONNECTION

Remove the wire joining Ri and L+ and connect the module
between Re and L+ terminals. Never connect an external
resistor in parallel with the internal Ballast resistor.

WARNING.
On top of the ER+TH modules, the air temperature
can reach values over 120°C/248°F. Therefore, the resistor
should be mounted away from the rest of the modules or even
outside the electrical cabinet, always vertically and away from
cables and other temperature sensitive material.

From version 07.02 on, the drive
may have a CAN board capable
of transmitting data at 1 MBd,
800 kBd or 500 kBd.
The communication speed
between all the drives being
governed by the CNC in the CAN bus
is selected by hardware using the
“BOOT” button on top of the CAN
board connector.
