Mounting, Hookup and Application Instructions
Mounting
Unless supplied connected, first connect the IRPT5051D and the
IRPT5051A power assembly.
1. Remove all particles and grit from the heat sink and power
substrate.
2. Spread a .004" to .005" layer of silicone grease on the heat
sink, covering the entire area that the power substrate will oc-
cupy.
3. Place the power substrate onto the heat sink with the
mounting holes aligned and press it firmly into the silicone
grease.
4. Place the 5 M5 mounting screws through the PCB and
power substrate and into the heat sink and tighten with fingers.
Control Connections
All input and output control connections are made via a female
connector to CN6.
Power Connections
3-phase input connections are made to terminals R,S and T. Inverter
output terminal connections are made to terminals U,V and W.
Positive and negative dc bus connections are brought out to ter-
minals P (positive) and N (negative). An external braking circuit
can be connected across terminals P and N.
Logic Sequence During Power-Up
When 3-phase input power is first switched on, PWM inputs to
the IRPT5051 must be inhibited until all the following logic con-
ditions are met:
1. external 15V supply is established
2. UV feedback signal is low, indicating local power supply
for gate drive circuits is established
3. K1FB signal is high, indicating capacitor precharge relay is
energized.
When these conditions are simultaneously met, a 15V RESET
pulse should be applied to the RESET input.
PWM input signals can now be released to the IRPT5051. The
first PWM input signal to each of the lower IGBT inputs (IN2,
IN4, IN6) should have at least 50μs duration, to allow the boot-
strap capacitors to charge.
Logic Sequence During Power-Down
The following sequence is recommended for normal power down:
1. reduce motor speed to zero by PWM control
2. inhibit PWM inputs
3. disconnect main power.

5. Tighten the screws to 2 Nm torque, according to the se-
quence shown below.
6. Re-tighten the screws to 4-5 Nm using the same sequence
as in step 5.
