The Fanuc A06B-6111-H006#H550 is an Alpha i series spindle amplifier module, also identified as the SPM-5.5i, used to control AC spindle motors on CNC machine tools equipped with Fanuc i series controls. The nameplate confirms a rated input of 283 to 339V DC at 6.8 kW, a maximum output voltage of 240V AC, and a rated output current of 27A. The module is marked Series B and carries serial number V03Y07536. The variant designation SP12 is shown on the side tab. Manual reference B 65282 is listed on the nameplate, and the unit is built to EN50178 and UL508C standards with CE marking. Manufactured by Fanuc Ltd in Yamanashi, Japan, this module is typically installed on small CNC lathes and vertical machining centers driving compact Fanuc AC spindle motors. Compatible cooling fans referenced for this drive include the internal fan A90L 0001 0510 and the external fan A90L 0001 0507#A. The module operates as part of the Alpha i drive stack, working alongside a Fanuc Power Supply Module (PSM) and connected via the high speed serial interface (HSSB) used across the Alpha i platform. Common applications include CNC lathes, machining centers, and turning centers using Fanuc 0i, 16i, 18i, 21i, 30i, 31i, and 32i series controls. The module supports vector control of the spindle and accepts feedback from position coders and motor sensors typical of Alpha i spindle systems.
