Kollmorgen S72402-NANANA-NA | S700 Servo Drive | 24 A Motion Control

Description

Key Technical Specifications

The 48 A peak rating applies to the standard S72402 model for approximately 2 seconds. Do not use the 72 A figure unless the nameplate confirms the extended-peak S7240S version.

Product Introduction

The Kollmorgen S72402 is a high-current digital servo amplifier for industrial motion systems requiring controlled motor torque, speed, and position. Its IGBT power stage converts the incoming three-phase AC supply into a controlled motor output. The drive includes current and speed regulation, an integrated position controller, and a DC bus architecture that supports energy sharing between compatible amplifiers. An internal dynamic braking circuit dissipates regenerated energy; an external brake resistor may be required depending on the application and braking duty.

The standard S700 configuration includes EtherCAT and CANopen communication, an RS-232 setup interface, feedback evaluation, and dual-channel STO. Three front-mounted expansion slots provide options for additional fieldbus, I/O, positioning, and safety functions. The exact installed options must be checked against the full order code and physical drive, particularly where a machine uses PROFIBUS, DeviceNet, SERCOS, SynqNet, or a dedicated positioning card.

Application Scenarios and Field Pitfalls

Typical applications

• CNC machine axes and precision positioning systems.
• Industrial packaging and material-handling machinery.
• Synchronous and asynchronous servo motor control.
• Multi-axis systems using EtherCAT or CANopen.
• High-inertia machinery requiring controlled deceleration and regenerative-energy management.

Engineering checks before replacement

1. Verify the motor rating. Check continuous and peak motor current, rated voltage, feedback type, and minimum motor inductance. A 24 A drive rating alone does not establish motor compatibility.
2. Confirm the supply network. The S72402 is the 208–480 VAC class. It is not interchangeable with the S7246 low-voltage-class version.
3. Check the peak-current variant. S72402 and S7240S have different peak-current capabilities. Do not assume their overload performance is identical.
4. Verify the communication option. The standard model has EtherCAT and CANopen onboard. Additional fieldbus options require the correct expansion card and slot configuration.
5. Check STO wiring. Verify both safety channels and the machine safety circuit before commissioning. STO is not a substitute for electrical isolation during maintenance.
6. Evaluate braking requirements. Confirm the internal brake resistor’s duty limits and whether an external resistor or DC-bus arrangement is required.

Related Products and Options

These are related models or documented options, not automatic substitutes. Confirm the required expansion-slot configuration and firmware compatibility before changing a drive.

Procurement and Quality Control

The S700 is a legacy drive family, and secondary industrial listings describe the variants as discontinued. Current OEM service and spare-part availability should be checked before planning a long-term replacement strategy.

Before purchasing, request:

• A clear photograph of the complete nameplate and serial number.
• Confirmation of the full order code, including the additional -NA suffix.
• Hardware and firmware revision.
• Photographs of the power, motor, feedback, and communication connectors.
• Confirmation of the installed expansion cards.
• Inspection for capacitor leakage, overheating, corrosion, and damaged terminals.
• Power-up, fault-history, and communication test records.
• A functional motor test under a compatible configuration, where possible.

Replacement recommendation: Specify the complete order code and verify the 24 A rating, 208–480 VAC supply class, feedback interface, fieldbus options, and STO wiring. Do not approve an S7240S or S7246 as a direct replacement without a documented engineering compatibility check.
