Product Description:

The SERVOSTAR-614 is a servo drive manufactured by Kollmorgen within the S600 Servo Drives series. It converts DC bus energy into controlled phase currents so that connected servomotors follow position, speed, and torque commands issued by higher-level PLC or motion controllers in automated machinery. This makes it suitable for coordinated axis control in systems that require accurate and repeatable motor response.

The drive can supply a continuous motor current of 14 Arms, which is its steady-state delivery limit without thermal derating. For short acceleration events, it can rise to a peak of 28 Arms, giving extra dynamic headroom during demanding motion profiles. System sizing is based on a total apparent power of 10 kVA, which helps with the selection of upstream fuses, contactors, and busbars. An output-current form factor of 1.01 indicates that its pulse-width-modulated waveform is nearly sinusoidal, which helps limit additional copper and iron losses in the motor. Heat generated under rated load is dissipated at 160 W, while standby mode draws only 15 W, helping keep enclosure temperatures lower during idle periods. Physical dimensions of 100 mm in width, 275 mm in height, and 265 mm in depth without connectors permit dense stacking, and the aluminum housing weighs 5 kg. A residual voltage drop of 5 V exists between the DC bus and motor terminals, which should be considered when calculating available motor voltage margin.

The control electronics are powered by a separate 24 VDC auxiliary supply. When a holding brake is fitted on the motor, this line must deliver 3 A. Systems without the brake need only 1 A, which reduces the demand on the low-voltage power supply. Allowed load inductance extends from 2.5 mH to a maximum of 15 mH, so the connected motor windings must remain within that range to maintain current-loop stability. Separating the auxiliary supply from the main power stage also helps the control section remain powered independently of the motor power path.
