Product Description:
The RS1E03AA servo amplifier is built by Sanyo Denki within the R SANMOTION Servo Drives series. It manages one motor axis and converts low-voltage mains power into precisely timed phase currents, allowing automated equipment to perform accurate positioning, velocity, or tension control. Its compact dimensions and DIN-rail mounting make the module suitable for multi-axis panels where each drive is dedicated to a separate machine element.
Output performance is supported by an amplifier capacity of 30 A, giving the axis short-term torque to overcome inertia during starts and stops. Both the control and main inputs use an AC 100 V system, so the drive connects directly to 100-volt supplies without auxiliary converters. Feedback flexibility comes from support for incremental and absolute encoders, allowing the drive to receive position data from either encoder type. Motion commands are accepted through an analog and pulse interface that supports ±10 V references or step-pulse streams from motion cards. Status lines use an NPN transistor configuration for straightforward connection to standard 24 V inputs. Continuous power draw is 0.8 kVA, which helps with sizing power feeds and planning thermal management. Because no internal braking resistor is fitted, an external braking component must be installed when the application requires dynamic deceleration.
The drive operates from 0 °C to 55 °C, allowing installation in ventilated industrial control panels. It tolerates ambient humidity of up to 90% RH without condensation, so moisture must not collect on internal electrical components. Its single-axis architecture simplifies wiring and keeps parameter sets focused on one connected motor. The assembly has a mass of 1.0 kg, making it suitable for lightweight panels and compact mounting structures. Adequate spacing and airflow should be provided when several R SANMOTION units are grouped in a confined enclosure. Panel placement should also permit access to the power, feedback, command, and status connections without placing excessive strain on the attached cables.
