Product Description:
The RS1L05AC is a servo amplifier produced by Sanyo Denki within the R SANMOTION Servo Drives series. Designed as a single-axis unit, it regulates current and velocity for a matched servo motor in positioning machinery such as pick-and-place actuators and indexing tables. By modulating its output according to encoder feedback, the drive enables repeatable motion profiles for industrial automation tasks. Its single-axis design is suitable for equipment that requires independent control of one servo motor without the added complexity of a multi-axis amplifier.
The amplifier section is rated at 50 A, allowing it to supply substantial peak current during acceleration without saturation. Its drive stage uses an IGBT PWM sinusoidal drive topology that supports closed-loop commutation with a frequency response of up to 600 Hz. Motor speed can be adjusted across a wide 1:5000 control range, and a tachometer input is unnecessary because the position loops use incremental encoder feedback. The unit accepts 200 V AC for main and control power, while the low-level electronics draw 24 V DC within a ±10% tolerance from a dedicated interface connector. Position control is executed in hardware, and NPN outputs permit direct connections to standard I/O cards. Thermal energy is dissipated through the chassis because the amplifier does not contain an internal braking resistor.
The wire-saving incremental feedback interface reduces the required cable count, while the optional absolute channel uses a battery backup method to preserve the machine origin during shutdowns. With the wire-saving incremental encoder active, commanded moves can reach a fast-forward velocity of 2,147,483.647 mm/s, supporting applications that require an extensive command range. The controller provides up to eight zone-area signals for supervising approach windows. It also supports 254 registration points for capturing product locations without interrupting the operating cycle. Despite these capabilities, the drive weighs only 2.2 kg, which eases panel installation and limits the load placed on mounting rails.
