The Yaskawa SGDA-01AP is a compact AC servo amplifier from the Sigma 1 Drive series, engineered for precise motor control in industrial positioning and speed regulation applications. This single-phase unit accepts 200-230 VAC input at 50/60 Hz and delivers 0-230 V output with 100 W rated power (0.13 HP). It employs IGBT-PWM control with exceptional speed regulation of 0.01% maximum at rated speed and voltage regulation of ±0.1% maximum, achieving a 1:5000 speed control range and ±2.0% torque repeatability.
The drive integrates auto-tuning and JOG operation modes, supports both incremental (2048 PPR) and absolute (1024 PPR) encoder feedback, and features electronic gear functionality for position control. A varnish-coated circuit board provides enhanced environmental resistance. PC monitoring via RS-232C (up to 2 m) or RS-422 for extended distances enables real-time diagnostics including I/O monitoring, speed and torque waveform display, and error messaging. The amplifier supports dynamic braking and external regenerative units, with selectable input signals for position control (reference pulse, 2-phase A/B, line driver) and speed/torque control (±2 to ±10 VDC variable range). Acceleration/deceleration times adjust from 0 to 10 seconds. The compact book-shaped design measures 16.00 × 13.00 × 5.50 cm and weighs approximately 0.80 kg, making it suitable for space-constrained installations while maintaining UL/CUL certification.
