1.3.3
1.3.3.1
Current Feedback from the Power Modules
PFC
When an active power factor corrector is used, a Hall effect isolated current transducer
is included on the power module design to measure the input current. This signal is
assigned to AN6.
1.3.3.2
BRAKE CHOPPER
Although not strictly required for correct control of a brake chopper, feedback of the
amplified shunt voltage is provided. This signal is brought to the analog prototyping
header J6 as BR_SHUNT. If AN14 is not already in use, then a 0.1" jumper may be
used to easily connect BR_SHUNT to AN14. Alternatively, a wire link may be soldered
into J6 to assign BR_SHUNT to any other available channel.
1.3.3.3
MOTOR POWER STAGE
Owing to phase symmetry of motors and the connection to their phases, a separate cur-
rent transducer is not necessarily required per phase. This has been taken advantage of
to reduce the number of feedback signals as is done in commercial applications.
Two alternative sets of current feedback signals have been allowed. The two sets
represent signals from transducers measuring output current to the motor or those
measuring switch currents referenced to the -DC bus. A given application tends to use
one type or the other depending on isolation, accuracy and cost requirements.
A maximum of 3 output transducers is allowed along with up to 4 switch shunts.
LK1-LK3 are used to change over between the two sets of signals for Phase#1-Phase#3.
In this instance, the isolated signals come from Hall effect transducers. As delivered, the
isolated signals are selected to match the (default) isolated configuration of the power
module. The Phase#1-Phase#3 current feedback signals are allocated to AN0, AN1 and
AN2. This has been done so that simultaneous sampling may be carried out on all three
phases. This is especially important for certain motor control algorithms.
The fourth shunt (if used) is allocated to AN10.
Note that the ICD/ICSP data and clock lines must be reallocated before the Phase#1
and Phase#2 current feedback channels may be used. See Section 1.2.4 for details.
1.3.3.4
DC BUS SHUNT FEEDBACK
Feedback of the current in the -DC bus shunt is provided.
This signal (BUS_SHUNT) is assigned to AN8
1.3.4
1.3.4.1
Voltage Feedback
ISOLATED VOLTAGE FEEDBACK
Isolated voltage feedback signals are accommodated through the use of a PIC12C671
located within the power module. This device has its own ADC and communicates with
the dsPIC device via a simple 2-wire (clock and data) serial communications interface.
These signals are assigned to SCLK1 and SDI1 via RF6 and RF7.
Re-synchronization of the serial link is achieved by asserting the FAULT_RESET line
on RE9 for a minimum of 2 μ s provided a FAULT does not already exist. For details of
the serial communication protocol, refer to the power module documentation.
The two signals passed back are the DC bus voltage and, for AC input power modules
with PFC, the rectified AC voltage.
A small amount of passive filtering is used on the clock and data lines to remove noise
spikes.
