QS1A15AA03G01T00

QS1A15AA03G01T00 is a Sanyo Denki servo amplifier in the Q SANMOTION Servo Amplifiers series. It has a 150 A amplifier capacity and accepts 200 VAC power input. Its IGBT PWM sinusoidal drive controls the motor using pulse-width-modulated sinusoidal output, while torque control regulates motor torque from the command signal. The torque command input operates at DC ±2.0 V. The amplifier is intended for a rotary motor and supports a wire-saving incremental sensor with 2,000 pulses per revolution for position and speed feedback.

The maximum input pulse rate is 5 Mpulse/s, allowing the amplifier to process high-frequency pulse commands. Its open-collector pulse rate is 150 kHz for compatible pulse-signal interfaces. A 3-bit alarm-code output communicates operating fault information to an external controller. The control circuit has a 40 A inrush current, while the main circuit has an 18 A inrush current. Motor current leakage is 3 mA.

A dynamic brake is built in to decelerate the motor when drive output is interrupted, and it has an energy capacity of 2,450 J. The built-in regenerative resistance is 6 Ω, allowing regenerative energy produced during motor deceleration to be dissipated as heat.
