Setup and Operation
1.2.5
Motor Position Feedback Interface
Interface to two different types of commonly used motor position feedback devices is
provided.
Note that no electrical isolation is provided on the board. The user must ensure that the
motor frame is correctly earthed (grounded) and that the position feedback devices are
isolated from the motor windings.
J3 (Halls) is intended for electrical commutation signals from (typically) Hall effect
devices. These signals are used for BLDC and SR motors and have edge transitions
aligned to the electrical cycle of the motor phases. The three inputs (A, B, C) are
connected to 3 input capture channels (IC1 - IC3) of the dsPIC device. Pull-up resistors
and a small amount of filtering are provided on the board. The inputs are therefore,
suitable for either open-collector or driven use. Clearly, the inputs can be used for any
input capture or I/O requirements the user may have.
J5 (QEI) is intended for a Quadrature (or Incremental) Encoder Interface. These
devices produce two position related pulse train outputs, 90° apart (A and B) and an
optionally index output (Z) that pulses once per revolution. A typical device will produce
many hundreds of pulses per revolution allowing high resolution position feedback and
high bandwidth speed measurement. The inputs have a very small amount of filtering.
Weak pull-down resistors are also fitted. The three inputs are connected through to the
dedicated inputs of the QEI module of the dsPIC device.
The digital power supply (+5V and 0V-"G") is brought out to the connectors for power-
ing the transducers. Series inductors are used to reduce electrical noise entering the
board. The user should ensure there is adequate local decoupling of the power supply
at the position transducer end of the cable. The maximum current that may be drawn
from the +5V supply is 200 mA. If the user wishes to use a transducer that requires
more current, then an external power supply should be used with a common
connection between the grounds made on the G pin.
To minimize electrical noise, a shielded cable should be used.
1.2.6
Oscillator
A 7.3728 MHz, low profile crystal (Y1) is provided on the board. In combination with the
internal PLL and programmable postscaler of the dsPIC device, this allows a wide
range of system clock frequencies to be generated. A low profile component is used to
clear the emulator device adapter.
1.2.7
RS-232 Serial Port
One of the dsPIC UARTs is connected to J8 via an RS-232 level shifting interface
implemented by U5 (MAX232A). Using RG2 and RG3 as port pins also provides
optional hardware handshaking using CTS and RTS. To use the handshaking, the user
must install links LK6 and LK7. As RG2 and RG3 are multiplexed with the I 2 C? clock
and data lines available on the digital prototyping header J7, both features can not be
used at once.
1.2.8
RS-485 Serial Bus
The second dsPIC UART is connected to J10 via an RS-485 level shifting interface
implemented by U8 (MAX485). A 120R terminating resistor may be connected across
the bus lines (A, B) by installing LK9. The user may (optionally) control the RX and TX
enable lines by driving RG0 and RG1. Pull-down resistors are used to ensure the RX
is enabled and the TX is disabled by default.
