A24 Accel time4 setting limits: 0.0-3600s factory default: 10.0s
A25 Decel time4 setting limits: 0.0-3600s factory default: 10.0s
Accelerate time: Set the output frequency time decide by the start
frequency reach the highest frequency time.
Decelerate time speed: Set the output frequency time decide by the
start frequency reach the highest frequency time.
A26 S-curve select setting limits:0~3 factory default : 1
To avoid shock taken place on mechanical START/STOP, use S curve
to accelerate and reduce speed.

Notice!
Set special mode when motor(high speed motor) or machinery need
special rotation moment of force adjustment.
The follow conditions should be meet when setting data A10～A17: A16≤
A14≤A13≤A11
Motor rotating moment of force increase with voltage increase in V/F
mode, but too much increase will cause such problems:
1、Over excitation cause AC drive errors.
2、Motor overheat and vibrate too much.
When increase voltage, check motor current and increase step by step.
The value of Parameter A35 must be higher than the lower limit of the
output frequency of Parameter A36. 100% is the setting value of Parameter 01-
00. The upper limit of output frequency = (A11*A35)/100
