Product Description:

The QS1A15AP0XXXXS00 is a servo amplifier produced by Sanyo Denki for the Q SANMOTION Servo Amplifiers series. By converting fixed-frequency input power into controlled three-phase output power, it drives matched Sanyo Denki servo motors in positioning and speed-regulated machinery found on production lines, packaging cells, and semiconductor tools. Its IGBT pulse-width modulation system produces a sinusoidal drive waveform for smooth motor operation across changing speed and load conditions. The amplifier regulates motor current in response to control commands, allowing the connected axis to accelerate, decelerate, and maintain its commanded position.

The power stage can deliver up to 150 A of phase current, while a built-in regeneration resistor with a resistance of 6 Ω dissipates excess energy during rapid deceleration. The drive supports a frequency response of 600 Hz, allowing the velocity loop to track rapidly changing command profiles. To protect cabinet breakers during startup, an inrush-prevention delay of 900 ms staggers the charging of the internal capacitors. Leakage current is limited to 3 mA per motor, helping installers account for protective-device requirements when several axes share a power source. The amplifier also contains a dynamic brake rated for 2450 J and a parallel regeneration circuit. When the enable signal drops, the brake applies electrical braking to slow the connected motor. Control boards monitor output using a 2.0 V per 100% current scale and a 2.0 V per 1000 rpm speed scale, providing clear analog reference signals for diagnostic measurements.

The control inrush path draws 40 A, and the main power circuit momentarily reaches 18 A when the DC link begins charging. A speed-command impedance of 10 kΩ minimizes the electrical load placed on the upstream motion controller. Closed-loop regulation spans a ratio of 1:5000, supporting precise low-speed indexing without sacrificing the motor’s available maximum speed. Output status can be observed through dedicated current and speed monitor signals, allowing operating behavior to be checked without interrupting the command path. All circuitry is housed in a fan-cooled package that weighs 6.8 kg, and the enclosure is suitable for direct mounting inside standard control cabinets with a depth of 200 mm.
