Sanyo Denki RRMA400 Multi Axis Servo Motherboard

Module Feature

Sanyo Denki RRMA400 belongs to SANMOTION R series multi-axis servo system 4-slot motherboard (backplane). AC200V main circuit power supply architecture, support up to 4 pcs of RR series servo amplifier modules plug-in installation. It realizes shared power supply and internal bus communication among each axis module, simplifies wiring and cabinet layout. Supports pulse command interface, match SANMOTION R series servo motors. Built-in power distribution circuit and interlock signal path, with overcurrent and overvoltage protection signal transmission function. Widely applied to multi-axis precision motion platform in semiconductor wet bench and chemical automation equipment.

Working principle

The RRMA400 backplane provides shared DC bus power and internal signal bus for 4 servo amplifier modules. External control command is transmitted to each servo module through backplane signal routing. Each axis drive module communicates via backplane bus and outputs three-phase power to corresponding servo motor to realize torque, speed and position closed-loop control. When any axis triggers fault, backplane transmits interlock signal for safety protection.

Onboard components

Main power distribution circuit, internal communication bus connector, module slot connectors, interlock signal circuit, power terminal block, alarm signal terminal, aluminum base plate.

LED indicators

Power status LED and system fault LED on backplane edge.

Hardware self-diagnosis

Visual inspection of connector pins and PCB surface; power-on voltage measurement of each slot bus; continuity test of interlock signal; module insertion and communication handshake test.

Programming software

Sanyo Denki SANMOTION servo setup software for multi-axis parameter configuration, axis assignment and alarm log reading.

System compatibility

Compatible with Sanyo Denki SANMOTION RR series servo amplifiers and RM / R2 series servo motors for automation multi-axis positioning.

Function

RRMA400 backplane manufactured by Sanyo Denki. It supplies shared bus power and internal signal transmission for multiple servo drive modules, supporting synchronous multi-axis positioning. Damaged connectors or poor contact will trigger system interlock and stop motion. It is multi-axis base platform for semiconductor wet bench and chemical automation equipment.

Installation

Follow lockout/tagout safety procedure before installation. Power off the whole servo system completely. Mount backplane on DIN rail inside cabinet. Install servo amplifier modules into slots, wire main power cable and control signal cables. Configure multi-axis parameters via SANMOTION software, test communication and axis movement verification before formal operation.

InterfaceMain power input terminal, module slot connectors, alarm signal terminal, emergency stop terminal, status LED indicators on housing of RRMA400.

Diagnostic

System no power: Power supply missing or damaged backplane circuit.

Module communication failure: Poor slot contact or broken bus wiring.

Overvoltage interlock: Abnormal input voltage or faulty power circuit.

Axis cannot be enabled: Emergency stop activated or interlock signal loss.
