Product Description:
The RS2A05A0AA0W00 is a servo drive module produced by Sanyo Denki for the R SANMOTION Servo Drives series. It functions as the power and control interface between a motion controller and a matched SANMOTION servo motor. The module converts command signals into regulated phase current so that automated equipment can position loads or regulate their speed with high accuracy.
This model delivers up to 50 A of amplifier output and uses an IGBT PWM sinusoidal drive topology to achieve clean, low-distortion waveforms. During energization, the control circuit can draw as much as 40 A of inrush current, while the main bus faces a separate surge of 18 A; both values assist with upstream fuse and breaker selection. The frequency response of the current loop is rated at 600 Hz, supporting precise torque regulation on high-bandwidth axes. Leakage current to ground is limited to 1.5 mA, meeting common safety limits for grounded industrial cabinets. A built-in dynamic brake dissipates regenerative energy during rapid stops. A built-in transistor network handles continuous regeneration without external resistors. No external encoder interface is provided because feedback is received from the motor’s serial encoder.
For position commands, the pulse input channel accepts up to 5 million pulses per second, and the speed loop permits a control range of 1:5000 from base speed down to stable low-speed operation. Analog supervision is available through a 2.0 V ±10% speed monitor, a DC ±2.0 V ±15% torque-limit input, and a 2.0 V ±10% torque monitor output. These channels allow real-time observation without placing an excessive load on the drive electronics. Motor feedback is read exclusively from the serial encoder, and a secondary encoder cannot be attached. The unit has a mass of 2.2 kg, which helps simplify cabinet mounting. Cabling requirements remain minimal because the power-dissipation and braking hardware are integrated into the module.
