Product Description:
The BJRL-20012-110001 drive produced by Kollmorgen belongs to the Goldline Smart Drives series. It is an AC servo amplifier that conditions mains power for brushless motors and coordinates motion axes in industrial automation. The unit regulates motor current, manages regenerated energy, and exchanges input and output signals with a machine controller. These functions allow the amplifier to control motor torque and respond to commands from the connected automation system.
The servo loop bandwidth reaches 2.5 kHz, allowing the current regulator to respond rapidly to torque disturbances. Continuous output is rated at 12 ADC, providing steady motor excitation during sustained operation, while a peak capability of 25 ADC supports short acceleration periods without saturation. The internal resistor dissipates up to 30 W of regenerative power before external braking hardware is required. Motor inductances as low as 250 µH are supported, so the drive can control compact windings without excessive current ripple. Overvoltage protection activates at 195 VDC, and the regeneration circuit opens at 190 VDC to keep the DC bus below critical limits. The switching devices operate at a PWM frequency of 22 kHz, which reduces audible noise and current ripple. A peak regeneration current of 20 ADC is available during rapid deceleration.
This model is supplied in its standard configuration with an IEC three-prong line cord for direct connection to plant mains. Control wiring is consolidated on a 25-pin DB connector that routes 14 digital inputs and 6 digital outputs for sequence control and alarm reporting. This centralized connection reduces the number of separate control terminations required around the drive. An embedded memory capacity of 16 K stores motion parameters used by the control system. The drive permits master or slave operation so multiple axes can execute synchronized motion profiles. During deceleration, regenerated energy is managed through the braking circuit to prevent the bus voltage from exceeding the protection threshold.
