Product Description:
Kollmorgen manufactures the PRD-B040AAIB-63 CD Servostar drive. It is a 3-phase, 230V frequency inverter for industrial automation. 2 HP rated load, so suitable for applications that require precision motion control. The drive has several key specifications. The current loop, which controls the motor current and thus the torque, has a 62.5 μs (16 kHz) update rate and 2400 Hz bandwidth. This fast update rate allows the drive to react quickly to changes in load or speed commands and minimizes current ripple. The high bandwidth also enables the current loop to track rapidly changing current demands. This is critical for dynamic applications where the motor torque needs to be adjusted quickly and accurately.
The velocity loop, which controls the motor speed, has a 250 μs (4 kHz) update rate and 400 Hz bandwidth. These are critical for precision speed regulation. The 4 kHz update rate allows the drive to adjust the motor speed quickly to the setpoint even in disturbance. The 400 Hz bandwidth is the frequency range the velocity loop can control the motor speed. A higher bandwidth allows for faster speed changes and more accurate tracking of speed commands. The velocity loop also has a 1 rpm resolution via serial communication, so you can have very fine speed control. This level of precision is critical for applications where small speed variations can affect the final product quality.
The drive’s commutation loop, which controls the switching of the motor phases, also has a 62.5 μs (16 kHz) update rate and a maximum frequency of 400 Hz. Fast switching is required to generate the desired motor torque. The PRD-B040AAIB-63 uses a sinusoidal commutation loop output waveform. This type of waveform is preferred as it minimizes torque ripple and makes for smoother motor operation compared to other commutation methods. Smoother operation means less vibration, noise and wear on the mechanical parts of the system. The 50 dB analog input common mode rejection (CMR) helps to minimize the noise in the system so the drive’s control is accurate.
