Product Description:
The RS2A01A2MA3E00 is a servo drive amplifier produced by Sanyo Denki and placed within the R SANMOTION Servo Drives series. It is intended to regulate torque, speed, and position for a single rotary or linear motor in automated machinery by converting control commands into accurately metered phase current. Through this function, the unit links motion controllers with field actuators so that manufacturing lines, inspection gantries, or pick-and-place stages can execute repeatable movements under closed-loop feedback.
This amplifier can deliver up to 15 A of output current to the motor phases, indicating the maximum continuous current that the connected winding may draw without derating. It is a single-axis model, so one amplifier manages one motor channel, simplifying cabinet layout when only a single mechanical axis is present. The power section accepts a mains supply of AC 200 V, allowing direct connection to common 200 V industrial feeders without an intermediate transformer. Command signals arrive through a selectable analog or pulse interface, enabling either ±10 V velocity references or step-and-direction pulse trains from a motion controller. The internal digital signal processor interprets both command modes and generates synchronized pulse-width modulation patterns for motor control.
Position feedback relies on an absolute encoder, so the drive powers up with the motor position available without requiring a homing routine. The encoder uses optical sensing, which supports accurate feedback in electrically dense enclosures. Incremental data reaches the controller at 2.5 Mbit/s over a half-duplex asynchronous channel. Primary feedback comes from a serial motor encoder, while a pulse encoder can be connected as an external reference. Multiturn position has a 16-bit resolution, providing position history across 65,536 revolutions. Each individual revolution is subdivided using a 17-bit single-turn resolution for precise angular interpolation and responsive position control during repetitive machine movements.
