INFRANOR GMBH MSM Series Technical Notes

The INFRANOR GMBH MSM series represents a family of servo drive boards and motion control modules engineered for continuous-duty industrial environments. Deployed across chemical processing plants, oil refineries, nuclear auxiliary systems, and heavy manufacturing lines, MSM-series boards occupy a critical position in legacy and mid-generation servo drive architectures. Their compact PCB form factor, deterministic PWM output stages, and robust fault-isolation logic made them a preferred OEM choice for machine builders across Europe and Asia throughout the 1990s and 2000s. As installed base units age into their maintenance phase, sourcing verified replacement boards has become a primary operational concern for plant engineers and MRO procurement teams worldwide.

The Evolution of MSM Series Architecture

The MSM series was introduced by INFRANOR GMBH as a modular drive board platform designed to interface with the company's XtrapulsPac and SMT-BD1 servo amplifier families. Early-generation boards (MSM0404, MSM0606) used analog reference signal conditioning with discrete IGBT gate driver circuits. Mid-generation revisions introduced surface-mount gate driver ICs, improved thermal management layers, and expanded fault diagnostic registers accessible via RS-232 or CANopen interfaces. Late-generation variants added encoder feedback conditioning circuits compatible with EnDat 2.1 and SSI absolute encoders.

MSM Series Full Catalog & Functionalities (SKU List)

The following SKUs represent verified models within the INFRANOR GMBH MSM drive board series, classified by functional role:

Drive & Power Stage Boards

• MSM0404: 4A/4A dual-axis drive board; lower-current variant for compact servo axes.
• MSM1212: 12A/12A high-current drive board; used in heavy-duty spindle and feed axis applications.
• MSM0808: 8A/8A mid-range drive board; balanced current rating for general servo axes.
• MSM1515: 15A/15A drive board; configured for high-torque servo motor applications.
• MSM2020: 20A/20A drive board; heavy industrial servo axis, typically paired with liquid-cooled chassis.

Control & Signal Conditioning Boards

• MSM-CTL01: Main control board; hosts DSP, reference input conditioning, and fault logic.
• MSM-CTL02: Enhanced control board with expanded I/O and CANopen node support.
• MSM-ENC01: Encoder interface board; supports incremental TTL and differential encoder inputs.
• MSM-ENC02: Multi-protocol encoder board; EnDat 2.1, SSI, and Hiperface compatible.
• MSM-ANA01: Analog reference conditioning board; ±10V input scaling and offset adjustment.

Communication & Interface Modules

• MSM-PROF01: PROFIBUS-DP interface module; cyclic process data and acyclic parameter channel.

Power Supply & Auxiliary Boards

• MSM-PSU01: Internal auxiliary power supply board; generates ±15V and +5V logic rails.
• MSM-PSU02: Reinforced power supply board; extended temperature range for harsh environments.

Quality Control for the MSM Series Range

MSM series drive boards present specific test challenges due to their integrated gate driver and current feedback architecture. DriveKNMS applies the following test protocol to all MSM boards prior to dispatch:

• Visual inspection: PCB trace integrity, solder joint condition, component seating, and connector pin condition checked under magnification.
• Static electrical test: Insulation resistance and continuity verified across all power and signal nets before energization.
• Dynamic load test: Board installed in a reference SMT-BD1 chassis and operated under controlled resistive load at rated current (e.g., 6A per axis for MSM0606) for a minimum burn-in period.
• Gate driver verification: PWM switching waveforms measured at IGBT gate terminals; rise/fall times and dead-band intervals verified against INFRANOR factory specifications.
• Fault response test: Overcurrent, overvoltage, and encoder loss fault conditions induced and board response verified against expected fault code output.
• Thermal imaging: Infrared scan performed at full load to identify abnormal heat distribution indicating marginal components.

All tested units are issued a DriveKNMS test certificate recording test date, technician ID, chassis used for testing, and measured parameters. Boards that do not pass all test stages are quarantined and not offered for sale.
