KUKA 00-250-623 DC Radial Fan 24V Papst for KR C4 Cabinet

KUKA 00-250-623 DC Radial Fan 24V Papst for the KR C4 Fan Module

The KUKA 00-250-623 is the 24 V DC radial fan that sits in the fan module assembly of the KR C4 control cabinet. KUKA lists it as the DC radial fan 24V, Papst, and describes it as an integral part of the KR C4 fan module assembly, with the assembly installed inside the control cabinet and used for cooling. The fan weighs 0.16 kg and carries customs HS code 84145935. KUKA lists this article as the cooling unit for KR C4 and KR C4 midsize, and also under the additional fan for motor A1 in the KR QUANTEC press family. Send us the article number on the fan in your cabinet or the controller serial number, and we confirm the match before you order.

Industrial Applications

• Replacement of the cooling fan in the KR C4 fan module assembly when the cabinet reports an overheating fault or the fan has stopped.
• Cooling of the KPP and KSP power supply and drive modules in the robot control cabinet, where the heat has to be moved out of the cabinet.
• Service on robots running in continuous duty in hot production halls, where the cabinet cooling runs for the whole shift.
• Additional fan for motor A1 on KR QUANTEC press robots, where KUKA lists the same fan for that position.
• Spare holding for service teams that keep cabinet cooling parts on the shelf instead of waiting for one to be sourced.

Design Purpose

A robot control cabinet runs on power, and the power modules inside it turn into heat. The fan module assembly is the part of the KR C4 cabinet that moves that heat out, and this radial fan is the moving part inside it. A radial fan is used here rather than a plain axial fan because the blower wheel pushes air through the cabinet cooling circuit at a pressure the housing can handle, and that is what carries the heat from the drive bay to the outside air. The fan itself is small, at 0.16 kg, but it runs continuously while the robot is powered, which is why it is a wear item and why the cabinet temperature is the first thing to check when the controller reports a thermal fault. The article number on the fan and the controller it came from are what confirm the match, because KUKA uses the same fan body in more than one position and under more than one article number.

Common Failure Modes

• The controller reports an overheating fault on the KPP or KSP heat sink, and the cabinet fan is the first item the KUKA troubleshooting table points to.
• The cabinet temperature climbs while the robot is running, and the drive or power supply drops out once the thermal protection reacts.
• The fan no longer turns, or it turns but the airflow is weak, so the cabinet cools poorly even though the fault is not yet reported.
• The fan runs noisily or rattles, which points at a worn bearing or a fan that is no longer balanced.
• Dirt and dust build up in the cooling circuit, which raises the cabinet temperature and makes the fan work harder than it should.

The KUKA KR C4 operating instructions list the heat sink overtemperature error for the KPP and KSP in the troubleshooting table, and the remedies it gives are to check the cabinet fan, check the ambient temperature, check and reduce the load in the program, clean the dirt in the cooling circuit, and check the ventilation slits and clearance at the installation site. Please contact us with the fault code shown on your controller for an accurate diagnosis of your cabinet. When the cabinet is overheating, the checks that separate a failed fan from a blocked cooling circuit and from a cabinet that is simply too hot at the installation site are whether the fan turns, whether the intake path and filter are clear, and how much heat the surrounding hall carries in.
