The Danaher DMC2 30151P servo drive is rated for 3.5 A at 3 phased 240 VAC, 0 – 400 Hz. The DMC2 series drives seems to have been sold as OEM products with different names like Kollmorgen, InMotion or Thomson Industries. These drives are available on surplus market for medical devices in radiology, so presumably used for positioning tables or x-ray heads.

Inside the Danaher DMC2
The bottom has connectors for mains input, motor output, control input/output and encoder connector. On the front is status LEDs, bus connectors and bus address rotary switches.
The controller board is marked CPU2E and uses a Intel S8029, or S86029, the text is hard to make out, it is from 1995. Memory consists of one AMD AM29f400bb 4 Megabit flash memory IC and two Samsung X6X1008C20 1 MB RAM ICs. A Xilinx XC95108 CPLD is assumed to be used for ADC data collection. IGBT drivers is assumed to the two ST L6376PD in PowerSO20 packages.
Servo drive breaking circuit board consists of a single IXYS IXSH35N100A IGBT and diodes. IGBT is maybe to switch between DC bus and breaking resistors. Breaking resistors is ceramic types rated for 50 Ohm at 50 Watt. The 3 phase full bridge rectifier consists of 6 IXYS DSEI30-06A diodes. The more advanced motor drive board uses a 3 phase full bridge of Infineon K30N60 IGBT. These IGBTs are rated for 600 V, 30 A and 112 A pulsed.
