5.2 Setting acceleration/deceleration time
: Acceleration time 1 : Setting of acceleration/deceleration time unit
: Deceleration time 1 : Automatic acceleration/deceleration
Function
1) For acceleration time 1 programs the time that it takes for the inverter output frequency to go
from 0.0Hz to maximum frequency .
2) For deceleration time 1 programs the time that it takes for the inverter output frequency to go
from maximum frequency to 0.0Hz.

Note1): Setting increment unit can be changed to 0.01 seconds by parameter f519.
Note2): f519=2: When the acceleration/deceleration time is set to 0.0 seconds, the inverter accelerates
and decelerates 0.05 seconds.
f519=1: When the acceleration/deceleration time is set to 0.00 seconds, the inverter accelerates
and decelerates 0.01 seconds.
● If the programmed value is shorter than the optimum acceleration/deceleration time determined by load
conditions, overcurrent stall or overvoltage stall function may make the acceleration/deceleration time
longer than the programmed time. If an even shorter acceleration/deceleration time is programmed, there
may be an overcurrent trip or overvoltage trip for inverter protection. (Refer to section 13.1 for details)
