blocks.
Output driver interface
The i116 output driver is a PWM switching amplifier capable of supplying 2ARMS
continuous and 4ARMS peak (for 1 second max.) at a switching frequency of
approximately 39KHz.
This driver is intended for driving brushless AC (BLAC) and brushed DC motors and
actuators. Depending on the motor type, the connection to the board must be done in a
different way. Figure 2 and Figure 3 show how to connect a BLAC and a DC motor to
the i116 board:
Figure 2: Brushless motor connection diagram
Figure 3: Brushed DC motor connection diagram
An over current protection mechanism is included in the board for security. Maximum
allowed currents are 2ARMS continuous and 4ARMS peaks (for less than one second).
The power phase can reach temperatures of more than 100ºC. Take due
precaution before exposing this area to human contact.

Communication interfaces
The LCC-10 is provided with two different communication interfaces:
•CAN interface
•RS-232 serial interface
CAN interface
The LCC-10 can communicate with a host computer via CAN interface. The CAN-Bus
(Controller Area Network-Bus) is a serial communication protocol developed by Bosch
for exchanging information between electronic control units on automobiles.
This system makes it possible to share a great amount of information between the
nodes or control units appended to the system, which causes a major reduction in both
the sensors used and the quantity of cables in the electrical installation.
The baud rate is user selectable from 125Kbps to 1Mbps (default value). Figure 4 shows
how to connect one controller to the host, and Figure 5 shows a multiple controller
configuration.
Bus termination resistors (120Ωbetween CANL and CANH at both ends of the bus) is
necessary for correct operation of the CAN bus (mainly for long distances and high baud
rates).
Figure 4: CAN interface connection
Figure 5: Multiple node connection
Chapter 2: Description 7
When using CAN interface, jumpers located near connector J1 must be placed (see
Figure 6).
Figure 6: For CAN communications, jumpers must be placed. Red points show pin
number one.
The LCC-10 is provided with two CAN connectors to simplify the cabling in multi-node
configuration. In this mode, the previous node on the bus could be connected to J2
connector (IN), and next node on bus could be connected to J1 (OUT).
Table 5 and Table 6 show the pin out of these connectors:
