Overview
The IRMD2336DJ is a reference design kit for the IRS2336DJ three phase gate driver IC with integrated bootstrap
functionality. The design kit includes a complete drive system board with an input rectifier, control power supplies,
digital motor control IC and power inverter. Safety features include protections against motor line-to-line and line-
to-DC Bus(-) short situations. The power stage features the IRS2336DJ gate driver and six discrete IGBT power
switches allowing for easy customization. The included PC based GUI software allows the user to drive an
Induction Motor in open-loop Volts-per-Hertz mode of operation using the on-board digital control IC. The motor
speed and system parameters such as PWM frequency and deadtime can be modified using the GUI. Alternately,
the IRS2336DJ gate drive input PWM signals can be supplied externally by patching in signals through an on-
board connector.

Safety Precautions
In addition to the precautions listed throughout this manual, please read and understand the following
statements regarding hazards associated with development system.
ATTENTION:
The ground potential of the IRMD2336DJ system is biased to a
negative DC bus voltage potential. When measuring voltage waveform by
oscilloscope, the oscilloscope ground needs to be isolated. Failure to do so may result
in personal injury or death.
!
!
!
!
ATTENTION:
The IRMD2336DJ system contains dc bus capacitors, which take time to
discharge after removal of main supply. Before working on drive system, wait three
minutes for capacitors to discharge to safe voltage levels. Failure to do so may result in
personal injury or death.
Darkened display LEDs is not an indication that capacitors have discharged to safe
voltage levels.
ATTENTION:
Only personnel familiar with the drive and associated machinery should
plan or implement the installation, start-up, and subsequent maintenance of the
system. Failure to comply may result in personal injury and/or equipment damage.
ATTENTION:
The surface temperatures of the drive may become hot, which may
cause injury.

!
ATTENTION:
The IRMD2336DJ system contains ESD (Electrostatic Discharge)
sensitive parts and assemblies. Static control precautions are required when installing,
testing, servicing or repairing this assembly. Component damage may result if ESD
control procedures are not followed. If you are not familiar with static control
procedures, reference applicable ESD protection handbook and guideline.
!
ATTENTION:
An incorrectly applied or installed drive can result in component damage
or reduction in product life. Wiring or application errors such as undersizing the motor,
supplying an incorrect or inadequate AC supply, or excessive ambient temperatures
may result in system malfunction.
!
!
ATTENTION:
Remove and lock out power from the drive before you disconnect or
reconnect wires or perform service. Wait three minutes after removing power to
discharge the bus voltage. Do not attempt to service the drive until bus voltage has
discharged to zero. Failure to do so may result in bodily injury or death.
ATTENTION:
Do not connect power factor correction capacitors to drive output
terminals U, V, and W. Failure to do so may result in equipment damage or bodily injury.
Debris When Unpacking
IRMD2336DJ system is shipped with packing materials that need to be removed prior to installation.
ATTENTION:
Failure to remove all debris and packing materials which are unnecessary
for system installation may result in overheating or abnormal operating condition.
