FANUC A06B-6250-H030 αiPS 30HV-B Power Supply Module

The A06B-6250-H030 supplies the common DC link for the connected αi-B servo and spindle amplifier modules. Its 30 kW continuous rating describes the power supply, rather than a motor-axis output rating. Regenerative control returns energy to the power source.

Select the power supply using the combined servo and spindle duty, acceleration demand and regenerative loading. Continuous, 30-minute and peak figures describe different operating conditions; the peak value is not a continuous power rating. Main power equipment capacity assumes operation at continuous rated output.

The three-phase main circuit provides drive power; the external 24 V DC circuit supplies control electronics. Include the current of every connected module in the 24 V supply budget. The manufacturer permits up to 15 SV/SP modules per power supply, subject to capacity selection and wiring requirements.

Install the applicable AC reactor and size the input breaker, magnetic contactor and wiring for the selected module and machine supply. Use a transformer when the main supply is outside the stated range. Input protection and reactors are separate system components.

This order is the standard A06B-6250 version. The manufacturer lists PFB-24 control-power backup support, but PFB-R and PFB-C Model B modules require the Level-up A06B-6252 version. Connecting PFB-R or PFB-C to the standard 6250 version causes the stated hardware-malfunction alarm; those versions are not interchangeable by power rating alone.

Install the module vertically and arrange the drive modules horizontally. Reserve the model-specific panel cut-out and maintenance area, separate power and signal wiring, and prevent dust or cutting fluid entering the cooling path. Keep exhaust flow unobstructed.

Ambient temperature affects the available operating time at short-term rating for both the power supply and AC reactor. Use the manufacturer’s temperature curve when the machine cycle depends on the 30-minute rating, rather than treating it as available at every cabinet temperature.
