Product Description:
The S77202-DNF2-PM is a servo drive manufactured by Kollmorgen within the S700 Servo Drives series. Acting as the power conversion and control interface between a three-phase supply and a servomotor, it delivers the regulated current and voltage needed for accurate motion control in automated assembly stations, printing equipment, and pick-and-place axes. It is suited to motion systems that require repeatable speed and position response during frequent starts, stops, and command changes. Physically, the housing measures 386 mm in height, 190 mm in width, and 244 mm in depth, and it weighs 13 kg, allowing installation on mid-sized backplates without additional bracing.
An auxiliary supply of 24 V DC maintains the drive’s logic circuits and the factory-installed fan controller even when the DC bus is de-energized. The enclosure is rated IP20, so the unit is protected against accidental finger contact and is intended for cabinet mounting. Its output stage is pulse-width modulated at 8 kHz, allowing fine current resolution and low motor ripple. During short acceleration bursts, the drive can deliver a peak current of 140 Arms, whereas continuous operation is limited to 72 Arms to keep semiconductor temperatures within design limits. All position-related input and output lines are referenced to a 5 V signal level, matching typical encoder and limit-switch electronics.
The incoming three-phase mains is specified at up to 50 kVA, ensuring the DC link can support rapid load changes without sag. Safety is addressed with a Dual channel STO circuit, which removes gate drive from the output transistors to achieve an emergency stop without mechanical contactors. A wide supply window of 208…480 V lets the unit operate in both low-voltage and high-voltage plant networks. Standard PCBs are used throughout the controller, and an expansion slot is occupied by the dedicated fan board that manages internal airflow. Combined with the fan-assisted cooling path, this range helps the output stage stay within thermal limits during lengthy production cycles.
