Using output connections 6 and 7, the user may connect an external braking resistor.
The user should consider the maximum and average power to be dissipated at the
required DC bus voltage when considering the resistor value. They should also
consider the peak allowable resistor current of 4A. For example, if regulating at 400V
then a 100 ? minimum value should be used which would allow 1.6 kW (at most) to be
dissipated.
The user may feed in an external DC supply using output connections 5 and 7. This
offers the simplest way for a user to bypass the PFC section of the unit. In the simplest
case all the user needs to do is use an external rectifier and fuse. The input current
rating when using the auxiliary DC input is 15A (RMS). The inverter output rating is
unchanged. Note that if using the auxiliary DC input, the internal fuse, soft-start, PFC
and ground FAULT protection is bypassed. It is up to the user to ensure adequate
external protection circuitry is used and incoming DC voltage is correctly regulated.
1.2.3
Connecting To The Control Board
The system has been designed so that the Microchip dsPICDEM MC1 Motor Control
Development Board (02-01648) plugs directly into the 37-pin, D-Type connector.
Section 1.7 “User Signal Connector Pinout (37-Pin, D-Type)” contains details of
the pin allocation.
Correct operation with the use of an extension cable can not be guaranteed as it may
introduce additional noise. If an extension is used, it should be as short as possible
and use screened cable.
The power module derives its low voltage power supplies from the control PCB. The
supplies on the isolated supply are taken directly from the control PCB via the 37-pin
connector. The supplies on the live side of the isolation barrier are derived using an
isolating DC-DC converter that is connected to the digital +5V supply input on the
37-pin connector. In this way, the power module may be used at any input voltage up
to the maximum. This arrangement is shown in Figure 1-4.
