Product Description:
The QS1A05AA04H01P00 is a servo amplifier manufactured by Sanyo Denki and supplied under the Q SANMOTION Servo Amplifiers series. Designed to pair with Sanyo Denki rotary servo motors, the unit converts single-phase AC input into controlled three-phase output through an IGBT PWM sinusoidal drive, allowing motion controllers to execute precise position commands. By combining a position-control interface with a built-in regeneration path, it supports compact axis modules in packaging equipment, electronics assembly systems, and other automated machinery.
Current delivery reaches 50 A, which is the maximum continuous motor current that the drive can regulate without thermal derating. The power stage belongs to the AC 200 V voltage class, making it suitable for standard factory power supplies in many regions. The control loop has a bandwidth of 600 Hz, allowing the amplifier to follow demanding acceleration profiles issued by the motion controller. Command signals arrive as differential pulses at rates up to 5 million pulses per second, preventing a loss of command resolution during high-speed motion. For emergency deceleration, the dynamic brake engages within 10 ms, minimizing overshoot when a fault or stop request occurs. Control power is single-phase, while the IGBT bridge produces a sinusoidal output that helps reduce motor heating.
Energy returned during rapid stops is absorbed by an internal 17 Ω resistor, eliminating the need for an external regeneration unit and simplifying cabinet wiring. Position feedback is handled by a wire-saving incremental encoder rated at 2000 pulses per revolution, which provides adequate angular granularity for medium-precision axes while reducing the required cable count. Protective leakage current remains within 1.5 mA, helping the installation meet grounding requirements. The speed loop provides a ratio of 1:5000, so the same axis can perform slow indexing and high-speed traverses under the same gain settings. The position interface is matched to the amplifier’s frequency response for consistent command tracking. The unit has a mass of 2.2 kg, which allows secure panel mounting without additional structural reinforcement.
