Product Description:

The SR03000-2G102A is an original Kollmorgen digital amplifier manufactured under the Servostar series. When interfaced with any of the Goldline motors by Kollmorgen, the SR03000-2G102A functions optimally to create a flawless motion control system. As with most Servostar drives, the SR03000-2G102A features fully digital control loops, self-tuning, and precision torque control. With its compact metal package, this digital drive has a modern construction, suitable for applications with tight installation space constraints. Rather than implementing a single control algorithm, the SR03000-2G102A can freely toggle between the following control algorithms: pole placement, PDFF, and PI. Due to its flexibility, this drive can accommodate various types of machines and applications.

Like other SR03 digital amplifiers, the SR03000-2G102A has a DC bus voltage input range of 110 to 360 volts. At this DC voltage range, the corresponding continuous output current per phase of the amplifier is 3 amperes. As a three-phase digital amplifier, the drive can safely transmit a peak phase current of 6 amperes for 2 seconds. Whenever the digital drive delivers the rated continuous current per phase, the equivalent continuous output power of the drive reaches 1.1 kilowatts. At any point in time, the SR03000-2G102A supports a maximum PWM switching frequency of 16 kHz.

The SR03000-2G102A comes with an exclusive MOTIONLINK software that allows the user to fine-tune the operating parameters for a specific application. The closed-loop velocity bandwidth of this device can reach up to 170 Hz, assuming an input resolution of 12 bits. To get the most out of this digital amplifier, the recommended operation range of the drive must be respected. Based on Kollmorgen’s official SERVOSTAR documentation, the SR03000-2G102A can operate safely at an ambient temperature range of 0 to 45 degrees Celsius.
