FANUC A06B-6087-H130 Servo Power Supply 127A

A06B-6087-H130 FANUC Servo Power Converter

Product Introduction

The FANUC A06B-6087-H130 power supply module serves as the energy backbone for modern CNC machining centers. This servo power converter transforms incoming three-phase AC into regulated DC power that feeds subsequent servo amplifier modules. Consequently, it plays a critical role in maintaining torque and speed accuracy during heavy cutting operations.

Specifically, the A06B-6087-H130 accepts an input voltage range of 200 to 230 VAC at either 50 or 60 Hz. Its rated current reaches 127 A, making it suitable for multi-axis systems that demand substantial instantaneous power. Meanwhile, the conversion efficiency exceeds 95%, which minimizes wasted heat and reduces overall energy costs over the machine's lifetime.

Furthermore, this power supply includes three layers of protection: overload, overcurrent, and overvoltage. These safeguards automatically shut down the unit if abnormal conditions occur, thereby protecting downstream servo drives and motors from damage. For maintenance engineers, this feature significantly cuts troubleshooting time because fault indicators pinpoint the issue quickly.

The FANUC A06B-6087-H130 also stands out for its mechanical flexibility. Weighing 11.34 kg, it supports both vertical and wall-mounted orientations. This adaptability allows integrators to optimize cabinet layout, especially in retrofitting projects where space is limited. Additionally, the air-cooling design uses a built-in fan that maintains safe internal temperatures across an ambient range of 0°C to 55°C.

Moreover, its high current capacity supports simultaneous acceleration on several axes without voltage sag.

Mechanical & Environmental Parameters

• Weight: 11.34 kg (25.00 lbs)

• Mounting: Vertical or wall‑mounted

• Cooling Method: Air cooled (forced fan)

• Operating Temperature: 0°C to 55°C

The robust mechanical construction resists vibration and shock commonly found in milling and turning applications. Additionally, the fan unit is field‑replaceable, which extends the service life without requiring full module replacement. Regular cleaning of the air intake grille helps maintain optimal cooling efficiency.

Installation Guidelines

Proper installation of the FANUC A06B-6087-H130 ensures both safety and performance. First, mount the unit on a flat, non‑combustible surface using M6 bolts. Maintain at least 150 mm clearance above and below the fan openings for unobstructed airflow. Next, connect the three‑phase input wires to terminals R, S, and T, observing the correct phase rotation—though the converter is phase‑sequence insensitive, consistent wiring simplifies future diagnostics.

For the DC output, connect terminals P and N to the common DC bus linking all servo amplifiers. Use cables rated for at least 150 A to handle peak currents. Additionally, install a fast‑acting fuse on the input side as a secondary protective measure. Finally, ground the chassis terminal firmly to the cabinet earth bar, as proper grounding reduces electromagnetic interference and enhances safety.

Important checks before power‑up:

• Verify that all input and output cables are tightly secured.

• Confirm that the cooling fan rotates freely without obstruction.

• Ensure that the total connected servo amplifier load does not exceed 127 A continuous.

Frequently Asked Questions (FAQ)

Q1: Can the A06B-6087-H130 run on single‑phase power?
No, this power supply requires a three‑phase input (200–230 VAC). Single‑phase operation will cause the undervoltage alarm and may damage the input rectifier stage.

Q2: How do I calculate the total current for multiple servo amplifiers?
Add the rated input currents of all connected amplifiers. The sum must stay below 127 A for the A06B-6087-H130. For peak loads, consider the duty cycle because milling typically uses short bursts rather than continuous full current.

Q3: What happens if the cooling fan fails?
The unit has an internal thermal sensor that triggers an overheat alarm when temperatures exceed 55°C. The servo power converter will shut down to prevent component failure. Replace the fan promptly using FANUC's designated spare part.

Q4: Is this module compatible with older FANUC 0i or 16i controllers?
Yes, the A06B-6087-H130 works with any FANUC CNC that uses the standard DC bus interface. However, always check your controller's power budget because older models may have lower total capacitance requirements.

Q5: How often should I clean the air filter?
Inspect the intake grille monthly. Clean it with compressed air (below 0.3 MPa) every 500 operating hours or sooner in dusty environments. Clogged filters reduce airflow and shorten the lifespan of this FANUC power supply.
