Product Description:

The S7240S-NANANA is a rack-mount servo drive produced by Kollmorgen for its S700 Servo Drives series. As a drive, it regulates the torque and speed of synchronous or induction motors within automated machinery. By supplying controlled three-phase power, the unit forms the interface between a motion controller and a plant’s actuators, allowing coordinated axes to follow programmed commands. The device is intended for installations that require high peak current bursts and fieldbus connectivity while maintaining compatibility with industrial safety architecture.

The drive accepts a three-phase supply from 208 to 480 V and elevates the DC link to as much as 900 VDC, enabling high dynamic response from connected motors. Its cabinet rating of IP20 means touch-safe but unsealed operation suited to protected control enclosures. During transients, the unit can deliver a peak phase current of 72 Arms for up to 2 seconds, a capability supported by the Extended Ipeak option and a switch-on rate of 30 cycles per hour. Continuous operation is backed by a rated input demand of 18 kVA, while pulse-width modulation is produced at 8 kHz to help minimize motor torque ripple. EtherCAT and CANopen are available onboard, eliminating the need for expansion cards and simplifying fieldbus wiring.

For continuous loads, the drive supplies 24 Arms, and it dissipates 330 W as heat at full output, so adequate panel airflow is required. Braking energy can be absorbed internally by a 23 Ω resistor rated at 200 W, but applications with rapid deceleration can route excess power to an external circuit that handles up to 4 kW. Mechanical dimensions are limited to 100 mm in width and 348 mm in height, allowing dense stacking in multi-axis cabinets. Acoustic output is limited to 65 dB(A), and dual-channel STO provides safety-oriented power isolation when the machine enters a safe stop.
