Kollmorgen TTE29360-1010-FA-13
Product Introduction: A factory-matched power resistor assembly used with Kollmorgen servo drives (BDS5, SERVOSTAR, early AKD) to absorb regenerative energy from decelerating motor loads that exceeds the drive’s internal bus capacitance and AC line regeneration capability. Prevents DC-bus overvoltage faults.
Detailed content
-
Key Specifications (typical for TTE29xxx family):
-
Resistance: ~10 Ω (common for 29360-1010 type; verify nameplate — “1010” often encodes 10 Ω / 1000 W class)
-
Power Rating: Continuous ~100–250 W; short-time peak several kW (duty-cycle dependent)
-
Chassis: Aluminum housed wirewound resistor, IP20 or enclosed
-
Connections: Screw terminals or flying leads
-
Mounting: Panel/DIN-rail mount with adequate clearance for hot surfaces
-
Label “FA-13”: Likely factory assembly / lead-length / connector variant
-
-
Function & Working Principle: When DC bus exceeds a preset threshold (~390 VDC on 230 VAC drives), the drive’s braking transistor switches ON, dumping excess energy into this resistor as heat.
-
Installation & Notes:
-
Mount in a ventilated area — resistor gets hot during braking.
-
Wire directly to drive’s “BR+” and “BR−” (or “R+ / R−”) terminals with appropriately sized cable.
-
Do NOT short the resistor terminals during operation.
-
Select resistance low enough to draw sufficient current but high enough not to exceed brake transistor rating.
