WARNING:
- This EVM is meant to be
operated in a lab environment only and is not considered by TI to be a
finished end-product fit for general consumer use.
- This EVM must be used only by
qualified engineers and technicians familiar with risks associated with
handling high voltage electrical and mechanical components, systems and
subsystems.
- This EVM operates at voltages
and currents that can result in electrical shock, fire hazard and/or
personal injury if not properly handled. Equipment must be used with
necessary caution and appropriate safeguards must be employed to avoid
personal injury or property damage.
- Always use caution when using
the EVM electronics due to presence of high voltages! DC bus Capacitors will
remain charged for a long time after the mains supply is disconnected.
- The EVM can accept power from
the AC Mains/wall power supply, only uses the live and neutral line from the
wall supply, the protective earth is unconnected (floating). The power
ground is floating from the protective earth ground, all of the ground
planes are the same. Hence appropriate caution must be taken and proper
isolation requirements must be met before connecting scopes and other test
equipment to the board. Isolation transformers must be used when connecting
grounded equipment to the EVM.
- The power stages on the board
are individually rated. It is the user’s responsibility to make sure that
these ratings (i.e. voltage, current and power levels) are well understood
and complied with, prior to connecting these power blocks together and
energizing the board. When energized, the EVM or components connected to the
EVM should not be touched.
TMDSHVMTRINSPIN is a DIMM100 controlCARD based motherboard evaluation
module showcasing control of the most common types of high voltage, three-phase
motors including AC induction (ACI), brushless DC (BLDC), and permanent magnet
synchronous motors (PMSM). The High Voltage Motor Control Kit has individual DC bus
and three-phase voltage sensing making this board for BLDC/PMSM control with C2000
LaunchPad™ development kits suitable for use with the sensorless InstaSPIN-FOC
algorithm.
This section explains the steps needed
to run the TMDSHVMTRINSPIN with the software supplied through MotorControl SDK. The
kit ships with the jumper and switch settings correctly positioned for connecting
with the controlCARD. Make sure that these settings are valid on the board as
described below, and then insert the controlCARD with the TMDSADAP180TO100 adapter into the TMDSHVMTRINSPIN board as shown in Figure 3-16.
CAUTION: Do not apply AC
power to the board before you have verified these settings!
- Make sure nothing is connected to
the board, and no power is being supplied to the board.
- Insert the Control card with
TMDSADAP180TO100 adapter into the [Main]-J1
controlCARD connector if not already populated.
- Make sure the following jumpers
& connector settings are correctly implemented as shown in Figure 3-17.
- [Main]-J3, J4, J5 and J8
are populated.
- [Main]-J9 and [M3]-J5 are
not populated for using a controlCARD with its own onboard emulation to
disable the XDS100 on HVKIT.
- [Main]-J7 is populated
between pins 2-3 (pins furthest from the DIMM 100 socket).
- Banana cable between
[Main]-BS1 and [Main]-BS5 is installed to bypass the PFC.
- Make sure that the DC Fan
shipped with the kit is connected to the DC Fan Jumper [Main]-J17 when
operating the motor under load > 150W.
- Two options to get DC Bus power
are as below, recommend using the external 15V DC power supply.
- [Main]-J2 is not
populated if using the +15V from an external 15V DC power supply. Ensure
that [M6]-SW1 is in the “Off” position, connect 15V DC power supply to
[M6]-JP1.
- [Main]-J2 is populated
with a jumper between bridge and the middle pin if using the +15V power
supply from aux power supply module.
- Turn on [M6]-SW1. Now [M6]-LD1
should turn on. Notice the control card LED would light up as well indicating
the control card is receiving power from the board.
- Connect [Main]-BS1 and BS5 to
each other using banana plug cord, and then connect one end of the AC mains
power or DC power to [Main]-P1.
- Connect the motor, encoder, and
Hall sensors to the kits as described in Table 3-2 and shown in Figure 3-17.
- Connect a supply voltage from an
AC or a DC voltage source to the voltage supply pins. Power should only be
applied when instructed to do so in Section 3.5, keep disconnected otherwise.
