Kollmorgen SBD2-20-1101-0000023/160-20
Product Name: External Dynamic Brake Resistor Module (SBD2 Family)
Product Introduction: This is a Kollmorgen external braking resistor used to dissipate regenerative energy from decelerating servo motors when internal drive braking capacity is exceeded.
Detailed content
Technical Specification:
-
Family: SBD2-20 (STEP-type plate/tube resistor)
-
Resistance: 23 Ω
-
Continuous Power: 2000 W
-
Short-time Power: 3200 W
-
Max Bus Voltage: 850 VDC
-
Energy Absorption: 200 kJ per 120 s cycle
-
Compatible Drives: AKD-x02407, S600/S601–S620, S700, S300/S400 (with 23 Ω class)
-
Protection: IP20 (BAR/BAS) or IP40 (BAFP) depending on sub-type
-
Certification: CE, UL, RoHS
Functional Characteristics:
-
Mounts outside cabinet or in ventilated zone
-
Reduces DC-bus overvoltage during rapid deceleration
-
Prevents drive fault F600 / overvoltage trips
Working Principle: During four-quadrant operation, motor acts as generator; energy is dumped into resistor through drive brake chopper.
Application Scenario: Vertical axes, high-inertia flywheels, frequent reversing conveyors, press feeds.
Installation Requirement:
-
Maintain 200 mm clearance (BAR) or 300 mm (BAS) free space around resistor
-
Use listed brake cable, separate from signal wiring
-
Torque terminal screws to drive spec
Usage Note: Never operate above 160 % of continuous rating; resistor surface exceeds 100 °C in normal use.
