Description

Schneider MDI1FRD34C7-EQ-N – MDrive 34 Integrated Stepper Motor

Product Overview

The Schneider MDI1FRD34C7-EQ-N is an integrated stepper motor from the Intelligent Motion Systems (IMS) MDrive 34 family. Available product references identify it as a two-phase stepper motor with an integrated motion-control drive, designed for compact machine-motion applications. The unit accepts a 12–75 VDC input and provides approximately 529 N·cm of stall torque. RS-422/RS-485 communication capability allows configuration and control within suitable motion systems. The 85 × 85 mm flange format follows a NEMA 34-style mechanical arrangement, while IP20 construction makes it intended for protected equipment installations.

Technical Specifications — MDI1FRD34C7-EQ-N

The available product documentation and supplier records consistently classify this unit as an MDrive stepper motor with integrated electronics, while the detailed specification identifies the EQ suffix with an encoder configuration.

Key Features and Benefits — MDI1FRD34C7-EQ-N

• Integrated motor and motion-control electronics
• Two-phase stepper motor architecture
• Wide 12–75 VDC supply range
• Approximately 529 N·cm stall torque
• RS-422/RS-485 communication capability
• Encoder-equipped EQ configuration
• 85 × 85 mm flange mounting
• NEMA 34 mechanical format
• Suitable for compact industrial positioning systems

An integrated stepper solution can reduce external drive wiring and cabinet components compared with a conventional motor-and-drive arrangement. For replacement work, however, the encoder option and communication configuration should be matched exactly.

Installation and Maintenance — MDI1FRD34C7-EQ-N

Before installation, verify the motor wiring, DC supply range, communication interface, encoder configuration, and mechanical mounting dimensions. Confirm that the machine controller is configured for the correct stepper-motor parameters.

Use appropriate ESD precautions when handling the integrated electronics. Inspect the connector, flange, shaft, and cable assembly for damage. After installation, establish communication with the motor and verify configuration parameters before applying the machine’s normal motion profile.

Personally, I would back up the existing motor configuration before replacement. With integrated motion hardware, retaining the original parameter set can save considerable commissioning time.

Product Warranty — MDI1FRD34C7-EQ-N

Warranty terms depend on supplier, equipment condition, and purchase agreement. For new, surplus, or refurbished units, confirm the exact suffix, encoder configuration, serial number, functional-test status, and warranty period before purchase. The part is listed as discontinued by some industrial-equipment suppliers, making exact identification particularly important for legacy machinery.

The Schneider MDI1FRD34C7-EQ-N is best managed as a complete integrated motion assembly, with electrical, mechanical, communication, and encoder compatibility verified before replacement.
