Product Description:
The 0090-A9710 is a compact servo drive from Kollmorgen’s PD Servostar Servo Drives series. It conditions low-voltage DC power and translates command references into regulated motor torque, speed, or position for automated machinery. By bridging PLC motion instructions with three-phase servo windings, the unit provides the closed-loop actuation required for pick-and-place axes, feeders, and small material-handling stations.
The drive accepts a control signal range of ±10 VDC and resolves that command with 14-bit precision, allowing fine incremental moves without encoder jitter. Its power stage is supplied from a 24 VDC input rail, drawing 6 A at full load for a continuous demand of 144 VA. Three optically isolated digital inputs accommodate limit switches or homing sensors, while a single relay output can forward ready or fault states to higher-level control circuits. Configuration and diagnostics are carried out through an RS-232 serial link, eliminating the need for proprietary adapters. For motion-control flexibility, the drive supports torque, velocity, and position modes, so the same hardware can accommodate diverse mechanical loads. An internal velocity loop updates every 4 kHz, keeping speed error low even when inertia varies between cycles.
The power stage delivers 5 A RMS per phase to the motor terminals at an output voltage of 15 VAC, yielding a continuous shaft capability of 130 VA. Current regulation is refreshed at a fast 16 kHz rate, reducing ripple and permitting smooth servo operation during quick direction changes. The current loop’s rapid response also helps the drive maintain commanded torque as the connected mechanism accelerates or decelerates. The housing measures only 140 × 108 × 51 mm, allowing multiple drives to mount side by side in shallow panels. Its compact enclosure is suitable for distributed control layouts where panel depth is limited and several low-voltage axes must be installed close together.
