CHINT NVF2G-S Series User Manual

8.3.3 Acceleration and deceleration time and curve setting
Acceleration time refers to the time required for the inverter to accelerate from zero frequency to the
maximum output frequency of F0.07; deceleration time refers to the time required for the inverter to decelerate
from the maximum output frequency of F0.07 to zero frequency.
● Linear acceleration and deceleration
NVF2G-S provides 4 groups of acceleration and deceleration time, which can be switched and selected by
digital input terminal X. For example: select X1 and X2 as the input switching terminals, and form 2-digit binary
numbers in turn (where 1 means that the setting function of the X terminal is valid, and 0 means that the
setting function of the X terminal is invalid).

8.4 Motor parameter self-learning
Motor parameter self-learning is the process for the inverter to obtain the parameters of the controlled
motor. The self-learning methods include: static self-learning and dynamic self-learning.
