Product Details:
KOLLMORGEN BJRL-20012-110001 is a brushless servo amplifier of the classic Goldline BJRL series, using V-MOS power technology. It accepts 3×35VAC three-phase input, DC bus 60V, rated output current 12A, and is specially matched with Kollmorgen Silverline H series brushless servo motors. It is widely used in small CNC feed axes, indexing rotary tables, textile machinery and precision positioning stations, supporting analog ±10V speed command and closed-loop speed/torque control. It is a compact rack-mounted legacy servo drive for low-power high-response closed-loop motion control.
This servo amplifier is equipped with differential analog setpoint terminals and separate power and feedback connectors, with strong anti-interference performance for oil mist and dusty workshop environments. It has built-in ballast braking circuit for energy dissipation during deceleration, and supports external brake resistor expansion. Front panel fault LED and BTB ready relay contact directly show running and alarm status for fast on-site troubleshooting. The switching frequency is 30kHz, which ensures smooth current output and low motor running noise.
Professional technicians can adjust current limit, speed loop gain and braking threshold on the drive according to load characteristics. Real-time monitoring of bus voltage, output current and internal temperature runs continuously. Once overload, overheating, overvoltage or feedback loss is detected, the drive will block output rapidly to protect motor windings and feedback components. The mechanical structure is shock-resistant, suitable for long-cycle continuous operation of automation equipment.
This KOLLMORGEN BJRL-20012-110001 servo amplifier has been discontinued by the original manufacturer. It is supplied as a tested aftermarket replacement spare part for legacy Goldline motion systems. Maintenance personnel can complete replacement safely after power cut, and the original H-series servo motor and mechanical installation dimensions can be kept consistent without large modification.
It is a classic low-power BJRL series rack servo drive spare part, commonly used for maintenance and retrofit of old small automation and CNC equipment.
