Product Description:
The QS1E01AA0H4A3P1T is a compact servo amplifier from Sanyo Denki built for the Q SANMOTION Servo Amplifiers series. It operates as the power and feedback interface between a motion controller and a brushless servomotor, converting low-level command signals into phase-controlled current while returning velocity and position data. The unit is suited to multi-axis industrial machinery that requires deterministic position loops and streamlined cabinet installation because of its 1.2 kg mass.
The electrical operating range centers on an amplifier capacity of 15 A, which indicates the maximum continuous motor current the module can regulate. Input energy is taken from a 100 V supply rail and switched through an IGBT PWM sinusoidal drive topology that lowers acoustic noise and improves motor efficiency. Two distinct inrush events must be considered: the control section momentarily draws 20 A when energized, and the power stage reaches 9 A as its bulk capacitors charge. A current-limit input of DC ±2.0 V ±15% lets the motion controller impose a ceiling on real-time torque demand. Leakage current is limited to 0.5 mA, supporting operator safety and compatibility with ground-fault detectors.
For command exchange, the amplifier accepts position pulses at up to 5 Mpulse/s on its differential input pair, aligning with a sensor feedback link that transfers data at 2.5 Mbit/s. Internally, the resolverless encoder channel delivers a 17-bit single-turn position and a 16-bit multi-turn count, so the drive resolves motion to fractions of a degree without external interpolation. Speed, torque, and current loops are driven by symmetrical DC ±2.0 V command ports. A speed monitor outputs 2.0 V ±20% per 1,000 rpm for use with diagnostic scopes. The position-control interface complements the torque-command port by allowing blended control modes within the stated voltage range.
