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.
