Product Description:

The QS1L01AJ0460MB01 is a servo amplifier produced by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. It converts the 200 V mains supplied to motion axes into precisely modulated phase currents through an IGBT PWM sinusoidal drive, giving machine controllers direct control over motor torque and velocity. By acting as the power interface between a motion CPU and a brushless servomotor, the unit supports accurate positioning, contouring, and speed regulation in packaging, assembly, and semiconductor equipment.

The rated output current of 15 A indicates the continuous load that the amplifier can support without derating. Compatibility with the 200 V input class allows the device to connect to standard factory power without transformers. Regenerative energy returned during rapid deceleration is dissipated by an internal 100 Ω resistor, protecting the DC bus from overvoltage. The amplifier has frequency characteristics of up to 600 Hz, allowing it to track high-frequency speed or torque commands with minimal phase lag. Closed-loop accuracy is supported by a wide 1:5000 speed control range. The analog reference ports have an impedance of 10 kΩ for both speed and torque commands, minimizing current draw from upstream controllers. A current monitor delivers 2.0 V at 100% output, while the speed monitor provides 2.0 V per 1,000 rpm for direct measurement during tuning. A built-in dynamic brake stops motor motion during faults or emergency stops.

The compact enclosure is 130 mm wide, 160 mm high, and 168 mm deep, permitting dense panel layouts beside other automation hardware. Its total mass is 1.25 kg, allowing the unit to be mounted without lifting equipment. Passive cooling is required because no internal fan is installed, so cabinet airflow must carry away switching losses while the fanless design eliminates periodic filter changes. Front-edge screw terminals keep the monitor outputs and command lines accessible inside crowded control panels.
