Product Description:
The RR1A01AAB00 is an AC servo amplifier unit produced by Sanyo Denki as part of the R SANMOTION Servo Drives series. Designed to coordinate rotary servomotors with position controllers, the module converts DC-bus power into controlled phase current so automated machinery can execute precise speed and torque profiles. In factory cells, it forms the power stage between a motion CPU and servo axes, allowing compact installation in assembly, packaging, or semiconductor equipment. The amplifier regulates motor current in response to incoming motion commands while using encoder data to maintain accurate positioning. Its modular format also supports cabinet layouts in which the power and control components are mounted on a common backplane.
The amplifier section has a continuous current rating of 15 A, providing sufficient capacity for moderate-torque rotary servomotors. A dedicated DC 280 V input supplies the converter, eliminating the need for an internal rectifier stage and reducing heat loss within the module. Control signals are accepted through a pulse-train interface, allowing step-and-direction or clock-and-direction pulses from a motion card to reach the drive without network delays. Position feedback is returned through a serial encoder channel that supports automatic resolution detection. The unit supports multi-axis operation, allowing compatible amplifier modules to share a common bus and regenerative brake resistor. Its single printed circuit assembly occupies one backplane slot, which helps conserve cabinet width and keeps adjacent drive connections accessible.
Within a complete R SANMOTION system, up to 6 amplifiers can be connected to provide a combined drive capacity of 2000 W across the shared DC bus. The command section has an open-collector output stage that follows the NPN convention, simplifying connections to standard sink-type I/O cards. The amplifier is designed for use with a rotary motor, and electronic current monitoring limits the commanded motion when operating conditions exceed permitted values. Safe Torque Off is not included, so external interlocking relays are required when the motor power must be isolated during maintenance or an emergency stop. A mechanical holding device may also be necessary when an axis must remain stationary after motor torque is removed.
