Overview

The proLIGHT 2500 was a sister machine to the 2000.    Both the 2000 and the 2500 are servo motor controlled.  The proLIGHT 1000 and later SUPER proLIGHT 1000 both used stepper motors.

Unlike the proLIGHT 1000 which used a ISA/PCI card to control an external stepper control box,  the 2000/2500 contains it's own servo controller and connects to the PC using an RS232 cable.

The proLIGHT 2000 had a belt driven R8 spindle which could run at either 5,000 (or, via a belt change, at10,000 RPM). The proLIGHT 2500 has an air-cooled direct drive EX16 spindle which runs at upto 42,000 rpm.   The motor is driven by a variable frequency drive (VFD) and requires a 10A 240V circuit.

I was told by Intelitek that they sold one 2500 for every thirty 2000s.

Electronics

Both the 2000 and the 2500 have a "backpack" mounted to the rear of the column which contains the electronics package.    There are two versions of this backpack.   

The first version is narrower with an auxiliary box optionally mounted to contain additional electronics (VFD on the 2500,  ATC on the 2000).   I believe it used the first generation servo controller pcb (LMC Servo Rev 1).

The second is wider allowing optional electronics to be mounted inside.   It also has a power switch on the front.   It uses the second generation servo controller pcb (32-8200-0002).

My 2500 came with a 5407M Animatics controller which means it is the later 7 series with all 4 axis populated but only 3 are used.      More information can be found on my Animatics page.

More information on the servo controller pcb can be found here.
