Excellent Braking Function
【Over-excitation Braking Function】
The over-excitation braking function can help with a prompt braking action even without the braking unit on some occasions.
【Dynamic Braking Function】
The braking torque could be higher and braking time shorter if working with a braking resistor.
The 0.75-22KW models are designed with built-in braking units.
(Remarks) The braking performance varies from motor characteristics and load conditions.
Superior Control Performance
The improved low frequency and high torque quick- starting performance brings a faster response speed and a higher production efficiency The probability
of equipment failure and shutdown can be reduced effectively with the enhanced current suppression algorithmso as to ensure a more stable processing capacity of the equipment.
Random Carrier Function
【Noise Reduction】
The random carrier function helps reduce the noise of the equipment so as to improve the environmental comfort.
Motor GND Short-Circuit Detection
The motor GND short-circuit detection function makes sure that the equipment is operating under normal andsafe conditions thus improving the safety coefficient.
