CHINT NVF5 Series User Manual

NVF5 Series User Manual Chapter 6 Parameter Function Description
6.3.3 Accel./Decel. Time and Curve Setting
The acceleration time refers to the time required for the inverter to accelerate from
zero to F0.07-maximum output frequency；the deceleration time refers to the time
required for the inverter to decelerate from F0.07-maximum output frequency to zero.
 Linear Accel./Decel.
NVF5 has 4 groups Accel./Decel. time,you can switch them by using digital inputs.For
example：Configure DI1 and DI2 as switch terminals to consist 2 binary digits（1means DI
setting is effective，0 means DI setting is ineffective）
 S Curve Accel./Decel.
NVF5 has 2 groups S curve Accel./Decel. mode，you can select by setting parameter
F1.12：
S curve Accel./Decel.1：When the target frequency is fixed, the output frequency
increases or decreases according to the S curve. It can be used in places requiring slow
start or stop, such as conveyor belts, etc.
S curve Accel./Decel.2：When the target frequency is dynamically changed in real
time, the output frequency will increase or decrease in real time according to the S curve.
It is suitable for occasions with high comfort and fast real-time response.
