I missed this conversation between EDI and engineer Adams on my 3 playthroughs. I'm glad there is some reasoning behind this.
HUMANS ARE DUST IN THE STELLAR WIND.
There are quite a few reasonable explainations. I can think of a dozen.
1. Stealth systems. Reapers don't exactly have optics arrays, so they probably see through sensors. Which the Normandy's stealth drive would make them invisible to. Organic beings give off heat, making them visible, but the Normandy's emissions sinks keep heat from getting out.
2. Updated Reaper IFF. EDI keeps the IFF's programs updated and unpredictable, that way they appear as a Reaper to scanners.
3. Cyberwarfare suites. EDI's firewalls and programs are based off of Reaper viruses extracted by Sovereign, and have evolved in what she described as "ways that would be computationally impossible to predict" meaning she might be able to hack Harbinger when close by.
4. It's not in his orders. Harbinger was guarding the beam. Shooting down the ship would distract him from blasting people who were trying to get to the beam. He cant risk someone getting through just because he has a grudge with Shepard's ship.
5. Shepard wasn't on the Normandy. Harbinger has always been fascinated by Shepard and wanted to study him. But he always gave orders to kill him if they couldn't bring him in alive.
6. No point in shooting down a retreating ship when his goal is to kill anyone who approaches the beam.
7. Harbinger's gun may not have been angled appropriately. If you notice, the Reapers generally only fire straight forward and don't have a lot of movement. Harbinger's had a little more, but every shot he fired was tecnically below him. The Normandy, at the point when he would have fired was above his range.
8. His gun may not have been able to pierce the Normandy's shields. Harbinger's gun fires smaller versions of the conventional Reaper laser as a trade off to being able to fire at multiple targets simultaneously. And the Normandy SR-2 has upgraded armor and shields from ME2. Cyclonic Barriers are more resistent than normal shields, and if they fail, the normal shields kick in. And if he gets through those, the Normandy has diamond coated silaris armor. Meaning Joker could have taken a few hits and still gotten away. Making firing at it a waste of time.
9. If the Normandy fell into the beam itself, it could destroy it, something that's just as detrimental for the Reapers as the organics. The Reapers set up the beam as a way to transport their harvested materials to the citadel for processing. The fact that Harbinger didn't just destroy the beam to keep Shepard's forces from going through means it's important to them to keep it running.
10. If the Normandy crashed on the beam, there's also a chance that it could be sent up into the Citadel(remember the Conduit on Ilos when Shepard drove the Mako into it.) And if it didn't explode, surviving crew members would be able to get the arms open. If it did explode, the ships mass effect core's explosion would be devestating and could damage the Catalyst's core, which is in the chamber right above the entry point as the ending shows.
11. Mass Effect core explosions also cause powerful shock waves. If the Normandy blew up in range of the beam, it could very well propel objects and people nearby into the beam. Like the people in the Makos who wouldn't be killed by the blast. Thus sending them up to the Citadel.
12. If the Normandy did get shot down, Shepard could call for more ships to come down. Which would begin firing on him to keep him busy while evacuating more people and allowing Shepard to get through to the beam. Harbinger was far away enough from the beam that it wouldn't interfere with shots fired on him.
