Product Q&A

Q:What control modes does the SF850 support?

The SF850 supports V/F control, sensorless vector control (SVC), and flux vector control (FVC). It can drive both asynchronous and synchronous motors with high precision, making it suitable for a wide range of industrial applications.

Q:How does the modular design reduce maintenance and after-sales costs?

The SF850 uses a modular structure: power module (PM), control module (CM), operation panel (OP), and expansion module (EM). If the power module is damaged, you can replace it without changing the control module, parameters, or control wiring. This greatly reduces downtime, labor cost, and re-commissioning time.

Q:What is the overload capacity of the SF850?

For G-type (constant torque / heavy load): 150% rated current for 60 seconds, and 180% for 3 seconds. For P-type (constant power / light load): 120% rated current for 60 seconds, and 150% for 3 seconds. This ensures reliable operation under demanding load conditions.
