Product Description:
The S7720-SNF2-NA is a servo drive manufactured by Kollmorgen for the S700 Servo Drives series. It regulates motor power, position, and velocity for coordinated industrial motion applications such as packaging lines, machining centers, and automated material-handling cells. Through an integrated SynqNet interface, the drive exchanges deterministic clocked data with a system controller, allowing multiple axes to remain synchronized during high-speed production tasks.
Electrically, the drive accepts a three-phase supply across a line range of 208 to 480 V and can deliver up to 72 Arms of phase current to the motor windings. The unit is rated for 50 kVA of input power, and its output stage switches at 8 kHz to reduce current ripple and audible noise. The analog command channel presents an input resistance of 150 kOhm, which keeps loading on upstream control electronics low. A residual 6 V drop appears across the output stage, so drive selection must account for that margin when calculating motor terminal voltage. Dynamic braking energy can be routed to a 10 Ohm external resistor to protect the DC bus during rapid deceleration. Onboard EtherCAT and CANopen interfaces remove the need for an expansion card, while motion commands are carried through the SynqNet network.
The unit measures 190 mm in width, 244 mm in depth, and 386 mm in height, and it weighs 13 kg. Heat is expelled by a controlled fan, and with the drive disabled, waste heat falls to 24 W, which helps reduce cabinet temperature when the axis is idle. During continuous regenerative operation, the braking stage can dissipate up to 8 kW into the connected resistor. A front-panel RJ-45 port provides the SynqNet connection, and the primary network controller identifies the drive as a SynqNet node. The listed dimensions help with cabinet spacing and airflow around the fan-cooled enclosure.
