Product Description:
The 0190-a2440 is a servo drive produced by Kollmorgen for the PD Servostar Servo Drives series. It regulates the torque, speed, and position of brushless servomotors in automated machinery. The drive links motion commands from a controller to the motor phases through controlled power delivery, making it suitable for compact positioning and velocity-controlled axes.
The drive accepts a command span of ±10 VDC on a differential analog pair with 14-bit precision, providing fine velocity and position references through its analog control interface. Onboard logic provides 3 digital inputs and 1 digital output for step, enable, and fault signals. The enclosure measures 140 × 108 × 51 mm, helping conserve space inside a control cabinet. Power arrives through a single DC bus rated at 24 VDC, 13 A, and 250 W, and this rail also supplies the internal logic circuits. The motor phases receive a sinusoidal output rated at 12 VAC, 5 A RMS per phase, and 220 W, which is suitable for low-voltage servomotors used on small axes. Control-loop frequencies of 16 kHz, 4 kHz, or 2 kHz can be selected to balance dynamic response and switching losses. An RS-232 service port supplements the differential analog interface and operates at either 9,600 or 19,200 bps for configuration and diagnostics.
For pulse-train operation, the command edge rate is limited to 2.5 kHz. Remote encoder feedback can be captured at up to 3 MHz, allowing electronic gearing or follower operation without missed counts. Closed-loop velocity regulation supports a bandwidth of up to 400 Hz, enabling the axis to reject load disturbances quickly when paired with stiff mechanical components. A dedicated 24 VDC logic supply pin supports external sequencing without requiring a separate control voltage level. The differential analog input helps reduce susceptibility to electrical noise in industrial cabinets and long control-signal runs. Selectable control-loop rates allow the response to be adjusted for different motor loads and machine inertias while preserving stable operation. The digital input and output channels also provide direct connections for basic machine-control functions without requiring an additional interface module.
