Preface
Thank you for choosing SINEE’s A90 series inverter.
Document No.: 31010180
Release time: 2020-5
Version: 101
The A90 series inverter is a high-reliability and small-sized inverter launched by
SINEE. It supports the three-phase AC asynchronous motor and permanent magnet
synchronous motor; a variety of international leading drive control technologies, such as the
vector VF (VVF) control and speed sensorless vector control (SVC); and speed output and
torque output.
Features of the A90 series inverter:
 No need for derating at the ambient temperature of 50°C;
 Small size, leading in the industry;
 Wide speed range and high control accuracy: VF/1:50; SVC/1:200; rated speed:
±0.2%;
 High load capacity in low-frequency band: VF/1Hz/150%, SVC/0.25Hz/150%;
 Perfect protections: protections against the overcurrent, overvoltage, overload,
overheating, etc.
Before using the A90 series inverter, please read this manual carefully and keep it
properly.
While connecting the inverter to motor for the first time, please select the motor
type (asynchronous or synchronous) correctly and set the motor nameplate
parameters: rated power, rated voltage, rated current, rated frequency, rated speed,
motor connection, rated power factor, etc.
We are committed to continuously improving our products and product data, so the
data provided by us may be modified without prior notice.
