KUKA 00-198-266 KSP 600-3x20 UL Servo Pack | KRC4 Drive

KUKA 00-198-266 — KSP 600-3x20 UL Servo Pack for KRC4 Controllers

The KUKA 00-198-266 is a KSP 600-3x20 UL servo pack (KUKA part of the KRC4 drive stack). It is the 3-axis drive amplifier that draws from the KRC4 DC link and delivers three matched 20 A AC axis outputs, driving up to three robot or positioner motor axes from one module.

Specifications

Industrial Applications

• Drives robot and positioner motor axes on KUKA KRC4 welding, handling, palletizing and general automation cells.
• Replaces a faulty KSP in the KRC4 drive cabinet to bring a downed axis back online.
• Used in multi-axis systems where one KSP 600-3x20 covers up to three lighter axes from the DC link.
• Suitable for production lines that must restore a single failed drive without replacing the whole control cabinet.

Design Purpose

The KSP 600-3x20 is the power stage of a KUKA KRC4 axis drive. It takes the DC link voltage from the controller cabinet and converts it into three matched AC axis outputs, each rated 20 A, to run the robot or positioner motors. When one KSP fails, only the affected axes lose power — swapping the failed module on the same controller generation restores the cell without touching the robot arm or the rest of the drive stack. The 3x20 rating (three 20 A axes) is the lowest-current member of the KSP 600 family, used for smaller or lighter robot and positioner axes, below the 3x40 and 3x64 packs — so the correct current rating must match the driven axes.

Common Failure Modes

• Overcurrent or short-circuit trip on one or more axes, stopping the robot with a drive fault.
• DC-link fault, where the KSP cannot hold the link voltage and the controller reports a DC-link error.
• Output-stage damage from motor or cable faults, leaving an axis without drive power.
• Overheating or internal component failure after years of service in a warm cabinet.
• Communication loss with the controller, preventing axis enable and motion.
• Verify by part number 00-198-266 and the controller type — send us your KRC4 controller label or drive-stack photo and we confirm the correct KSP rating before you order.
