Product Description:
The QS1L015Z178 servo amplifier is manufactured by Sanyo Denki as a member of the Q SANMOTION Servo Amplifiers series. The module conditions DC power and generates switching patterns to energize three-phase brushless motors in automated production lines. It interprets incoming position pulses and analog references, then delivers controlled current so actuators maintain commanded motion profiles. The amplifier supports compact, high-speed assembly cells, material feeders, and labeling systems while operating within the 200 V class power architecture used in many control cabinets.
The control section uses an IGBT PWM sinusoidal drive, providing loop stability while executing speed, torque, and position control routines. For incremental encoders, the amplifier accepts a 90-degree quadrature input at up to 1.25 million pulses per second, while a separate step-and-direction path reaches 5 million pulses per second. These high input rates support precise positioning when the connected motor has a high encoder resolution. Closed-loop bandwidth is rated at 600 Hz when load inertia equals motor inertia, allowing the system to correct velocity and torque deviations rapidly. A programmable gain structure supports a speed control range of 1:5000, maintaining repeatable shaft rotation from low speeds to the motor’s rated speed.
The speed and torque command channels each accept DC ±2.0 V, providing analog control references for the connected axis. The current monitor terminal produces 2.0 V at 100% output, allowing external equipment to observe amplifier loading without interrupting operation. A built-in dynamic brake helps stop the motor, and regenerative energy is routed to an internal resistor without requiring an external braking unit. The power, logic, and brake circuits share a built-in tray-type power supply, reducing panel depth and simplifying wiring. A separate speed monitor line provides velocity feedback at 2.0 V per 1,000 rpm, allowing the controller to verify actual motor speed. The torque limit signal uses a scale of 2 V per rated torque to help prevent the commanded load from exceeding the configured operating limit.
