Input and regeneration The PSM-55 supplies the Alpha drive group and returns regenerative energy toward the mains during deceleration.
⇄
Shared DC link Servo and spindle amplifier modules receive power through the compatible Alpha-series DC-link arrangement.
⚙
CNC machine role Used in high-capacity multi-axis machine configurations where the connected amplifier group determines sizing and reactor requirements.

12-month warranty and return route Report a concern within seven days. Keep the item in its original condition and state the reason clearly. A return or replacement can be arranged after receipt and inspection; return freight is paid by the buyer.
Can A06B-6087-H155 be selected only from the PSM-55 rating? No. Confirm the full order number, input class, connected servo/spindle group, cabinet wiring and any suffix option. Similar Alpha supplies can differ mechanically and electrically.
What should be checked if A06B-6087-H155 reports an overcurrent or DC-link alarm? Inspect the downstream amplifiers, motor circuits, busbars and regenerative path before replacing the supply. A secondary fault can damage the replacement module.
Why is fan condition important when purchasing A06B-6087-H155? Cooling degradation can raise heat-sink temperature and shorten power-component life. Verify fan operation, airflow path, dust loading and thermal alarm history.
What cabinet evidence helps confirm A06B-6087-H155 compatibility? Provide the complete module label, machine control family, neighboring amplifier numbers, input voltage, connector layout and clear cabinet photographs.
Should A06B-6087-H155 be energized immediately after long storage? Use an appropriate qualified commissioning procedure. Inspect capacitors, contamination, insulation, fans and damage first; high-energy DC-link equipment should be handled only by trained personnel.
