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.
