Product Description:

The QS1L01AA0M101S0F servo amplifier is manufactured by Sanyo Denki and belongs to the Q SANMOTION Servo Amplifiers series. The device conditions electrical power for a matched servomotor so that motion controllers can impose precise speed profiles in automated equipment such as pick-and-place heads, index tables, and transport axes. By converting line energy through an internal transistor bridge, the amplifier supplies responsive torque and relieves the host PLC of direct high-current switching duties.

It uses an IGBT PWM sinusoidal drive topology, a switching method that lowers harmonic distortion while maintaining smooth current delivery. The power stage is rated for a continuous output of 15 A, providing sufficient capacity for medium-frame servomotors during acceleration. The incoming supply must be in the industrial 200 VAC class, and an internal rectifier links this bus to a built-in dynamic brake and regeneration circuit so excess kinetic energy can be dissipated without external hardware. The amplifier supports closed-loop speed control, and the loop maintains stability up to a frequency response of 600 Hz. Within that bandwidth, commanded velocity can be adjusted across a range of 1:5000, allowing slow indexing and high-speed traverses from the same motor. Heat is removed by natural convection because a cooling fan is not installed, so the cabinet must provide sufficient airflow around the housing.

The front terminal block provides diagnostic voltages for process monitoring. Shaft speed is represented by a differential signal of ±2.0 V/1000 rpm, while developed torque is reported at ±2.0 V at rated torque. Both diagnostic outputs remain within the amplifier’s overall signal limit of ±8 V. These references support real-time feedback to data loggers without requiring separate isolation amplifiers. Safety is supported by a leakage current of 0.5 mA, and the metal chassis weighs 1.25 kg, making the unit easier to mount inside compact control panels.
