Heat sink temperature too high, KPP/KSP (axis)

What does 26040 mean?

This fault indicates an overtemperature condition on the heat sink of a KPP or KSP drive unit for an axis. Prolonged high temperatures can degrade component lifespan and lead to drive shutdown.

• High ambient temperature around the cabinet
• Excessive load in the robot program causing high heat generation
• Dirt or obstruction in the cooling circuit of the drive
• Blocked ventilation slits or insufficient clearance at the installation site
