Product Description:
The 0190-A2451 is a servo drive manufactured by Kollmorgen for the PD Servostar Servo Drives series. It regulates permanent-magnet servomotors in automated machinery, converting low-level motion commands into tightly controlled torque, velocity, or position outputs at the motor terminals. By integrating power electronics and real-time control loops, the unit provides a dedicated motion node that offloads the central controller and maintains repeatable axis performance in packaging, material-handling, and small assembly lines.
A 14-bit A/D converter captures feedback with 16,384 discrete levels, allowing fine current regulation. The command channel accepts a ±10 VDC analog reference, so the drive can follow proportional speed or torque setpoints from conventional PLC analog cards. The drive has three front-panel digital inputs that support enable, direction, or limit functions. It also has one digital output that returns drive status to external interlocks. During operation, the control loop sustains a 400 Hz velocity bandwidth, allowing it to track rapid speed changes without excessive overshoot. For position feedback, the differential encoder interface passes pulses at up to 3 MHz. The drive supports torque, velocity, and position operating modes selected through the analog control interface.
Panel space is conserved by an enclosure with a depth of 51 mm, a width of 140 mm, and a height of 108 mm, making side-by-side mounting possible inside compact cabinets. Internal logic circuits operate on 24 VDC, so the drive can share the same low-voltage rail used by sensors and contactors. For remote diagnostics, the RS-232 serial port exchanges parameters at a maximum rate of 19200 baud. The communication protocol carries absolute position data from encoders with up to 10 million lines per cycle. Its compact enclosure and standard serial interface support installation in distributed motion systems where cabinet space and access to operating parameters are limited.
