More Information

Overview Manuals Amplifier Group Regenerative Power Path External Power Magnetics Assembly Identification

Features:

  • PSM-55 power supply position in the FANUC alpha system
  • 200 VAC input, power-regeneration configuration
  • Shared power path for servo and spindle amplifier modules
A06B-6087-H155 identifies the PSM-55 unit that receives incoming machine power and supports the connected alpha-series amplifier group.

The module works with the input circuit breaker, magnetic contactor and AC reactor rather than operating as an isolated bench power supply.

Its regenerative architecture handles energy returned by the motor system while maintaining the common power path used by the adjacent servo and spindle amplifiers.

The FANUC A06B-6087-H155 PSM-55 Power Supply Module is listed as Active / Available from OEM. Apter Power can assist with A06B-6087-H155 purchasing enquiries and access to the available FANUC manufacturer documentation.

Position of A06B-6087-H155 in the Alpha Drive Group

  • Power-supply role: The PSM-55 provides the common DC link used by the connected spindle and servo amplifier modules.
  • Group architecture: FANUC documents the power supply module together with SPM and SVM units as one modular drive system.
  • System boundary: The installation also depends on the specified AC reactor, protective devices, connectors, and associated wiring.
  • Replacement impact: A fault or mismatch at the power-supply module can affect the full amplifier group, so downstream units should not be assessed in isolation.

Energy Flow Through the PSM-55

  • Incoming supply: The module accepts the documented 200 VAC class input through the required upstream equipment.
  • Common DC link: It establishes the 300 VDC link shared with the spindle and servo amplifier modules.
  • Regenerative operation: Returning motor energy is handled by the power-regeneration architecture rather than by an isolated axis supply.
  • Troubleshooting scope: Isolate the common power path and connected amplifier group before assigning a link-voltage problem to one downstream module.

Required Equipment Ahead of A06B-6087-H155

  • Circuit protection: FANUC specifies circuit breakers in the incoming power path for the amplifier system.
  • Controlled isolation: A magnetic contactor is required so the drive group can be disconnected under the documented control conditions.
  • Line interface: The specified AC reactor forms part of the input arrangement and should be matched to the amplifier configuration.
  • Surge control: Install the documented surge suppressor between the power lines and ground at the power-magnetics cabinet input.

Matching the Complete PSM-55 Assembly

  • Order identity: A06B-6087-H155 is the complete PSM-55 order specification used for replacement matching.
  • Unit marking: The maintenance table associates the #BM unit designation with this PSM-55 specification.
  • Board-level identity: A06B-6087-C155 and the listed PCB, driver-board, and connector-board numbers identify internal assemblies, not substitutes for the complete module.
  • Quote and repair check: Record both the full module label and any board markings so a board-level repair item is not ordered in place of the complete PSM.
Description
The FANUC A06B-6087-H155 PSM-55 Power Supply Module occupies the incoming-power position of a 200 VAC alpha-series servo and spindle amplifier group and establishes the common supply path for the connected amplifiers.

Motor energy returned during deceleration passes through the regenerative architecture of A06B-6087-H155. The operating relationship therefore includes the connected SVM and SPM modules rather than treating the PSM as an independent low-voltage power supply.

External equipment on the input side of A06B-6087-H155 includes the circuit breaker, magnetic contactor, and AC reactor. Their sizing, switching sequence, and wiring affect startup and regenerative behavior across the complete amplifier group.

A replacement for A06B-6087-H155 must retain the full order specification, PSM-55 capacity, 200 VAC class, common-bus connections, control connectors, and the installed servo and spindle amplifier combination. Selecting only by the PSM-55 name is not a complete system match.

Technical notes
A06B-6087-H155 is the PSM-55 regeneration supply; verify the full label, input devices, DC-link wiring and adjacent amplifier combination before replacement.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why must upstream devices be checked with A06B-6087-H155?
The breaker, magnetic contactor, and AC reactor form the A06B-6087-H155 input power and switching arrangement; incorrect sizing, sequencing, or wiring can create faults that appear to originate in the PSM.
What can cause a regenerative alarm after installing A06B-6087-H155?
After an A06B-6087-H155 exchange, check incoming voltage, AC reactor and contactor wiring, regenerative path, amplifier-group compatibility, motor operating conditions, and the complete order code.
What evidence best supports an A06B-6087-H155 replacement match?
For A06B-6087-H155, provide clear images of the full label, connected SVM and SPM units, power and control connectors, incoming supply arrangement, and any displayed alarm information.
Why should the connected amplifiers be recorded before replacing FANUC A06B-6087-H155?
The A06B-6087-H155 feeds a shared amplifier group, so PSM capacity and compatibility depend on the connected servo and spindle modules as well as the PSM-55 designation.
Is PSM-55 alone sufficient for selecting A06B-6087-H155?
No. A correct A06B-6087-H155 match requires the full order specification, 200 VAC class, PSM-55 capacity, and details of the installed servo and spindle amplifier group.
