SERAD MD SERIES MD400/2/R/F MOTION DRIVE CONTROLLER SN- 516.45

The SERAD MD SERIES MD400/2/R/F is a high-performance digital drive controller designed specifically for brushless servomotors. As part of the advanced Intelligent Motion Drive (IMD) evolution, this unit combines a powerful servo amplifier with a sophisticated motion controller, allowing for drastic simplification of traditional machine control architectures .

Designed for industrial environments requiring precise axis control, the MD400 series integrates PLC functionalities, an indexer, and an electronic gearbox (CamBox) into a single compact chassis. The MD400/2/R/F model offers robust power delivery and high-resolution feedback for demanding automation tasks.

Advanced Features & Capabilities

The MD Series (IMD) goes beyond standard speed control. It is equipped with native programming capabilities that reduce dependency on external PLCs.

1. Multi-Mode Operation

• Stand-alone Drive: Operates independently using internal programming.

• Controller Mode: Acts as an intelligent master in a multi-axis system.

• Slave Mode: Controlled via an external motion controller or PLC .

2. Integrated Intelligence

The drive supports complex motion profiles including:

• Electronic Cam (CamBox): Dynamic phase shifting and high-speed synchronization.

• Electronic Gearbox: Master/Slave following with programmable ratios.

• Flying Cutoff: Ideal for cutting-to-length or machining on the fly applications.

• Virtual Master: Synchronize multiple drives without a physical master encoder .

3. I/O and Connectivity

• Feedback: Supports Resolver (standard) and optional Hiperface / EnDat encoders.

• Analog I/O: 2 x Analog Inputs (16-bit resolution), 1 x Analog Output (±10V, 8-bit).

• Digital I/O: Opto-isolated digital inputs and NPN open-collector outputs.

• Communication: RS-232 serial port for programming; optional fieldbus extensions (EXT1/EXT2) .

4. Diagnostics and Safety

• 7-Segment Display: Real-time status and error diagnosis on the front panel (Error codes for Over-voltage, Following Error, Over-current, etc.).

• Protection: Short circuit protection, over-voltage protection (900V DC bus), and excess following error detection
