Stop detection frequency:

When the speed is reduced, the inverter will enter the stop state when the output frequency is less than this value.

Acceleration and deceleration selection

LED "0" digit: acceleration/deceleration time reference frequency
This parameter is used to select the basis for the acceleration/deceleration time.
0: Maximum frequency The reference for the acceleration/deceleration time is the maximum frequency [F00.09].
1: Fixed frequency The reference for the acceleration/deceleration time is 50.00 Hz fixed frequency.
2: Setting frequency The reference of acceleration/deceleration time is the set frequency. If the set frequency
changes frequently, the acceleration of the motor will change, so pay attention to the application.
LED "00" digit: acceleration and deceleration mode
This series of inverters provides two kinds of acceleration and deceleration modes; two kinds of acceleration and
deceleration modes are valid during normal start, stop, forward and reverse, acceleration and deceleration.
0: Straight line Generally suitable for general purpose loads.
1: S curve S-type acceleration and deceleration curves are mainly provided to reduce noise and vibration during
acceleration and deceleration, reduce the start-stop impact or low-frequency need to reduce the torque, and the
high-frequency needs short-time acceleration and other loads.

Schematic diagram of S curve
Tips:
 After setting the S curve, the acceleration/deceleration time will be extended as follows:
Acceleration time = selected acceleration time + ([F01.17]+[F01.18])/2
Deceleration time = selected deceleration time + ([F01.19]+[F01.20])/2
 The acceleration S curve is divided into three segments. Start S curve time [F1.17], acceleration time
[F0.14], end S curve time [F1.18]. Total acceleration time = acceleration time [F0.14 ] + ([F1.17]+[F1.18])/2,
try to ensure the selected acceleration time [F0.14]≥([F1.17]+ [F1.18])/2. When [F0.14 ]< ([F1.17]+ [F1.18])
/2, the total acceleration time will be calculated by the software itself and will deviate from the set time.
The deceleration S curve is the same as the acceleration S curve.

Acceleration time 2/3/4:

When the parameter [F01.16] LED "0" digit is set to "0", it refers to the time required for the output frequency to
accelerate from 0.00Hz to the maximum frequency;
When the parameter [F01.16] LED "0" digit is set to "1", it refers to the time required for the output frequency to
accelerate from 0.00Hz to 50.00Hz;
When the parameter [F01.16] LED "0" digit is set to "2", it refers to the time required for the output frequency to
accelerate from 0.00Hz to the set frequency;
