Parameter
01
-- Acceleration Time 1
Units
= Seconds
Range
= 0000/1600
Factory Setting = 005.0
This parameter determines the time that it will take the drive to accelerate
over a 60 Hz change in frequency. From 0 to 0.5 Hz, the accel rate is
effectively zero. From 0.5 Hz to maximum output frequency, the accel rate
set by Parameter 1 will remain constant. The total time it will take the drive
to accelerate from 0 to maximum drive output frequency is:
Total time = (Maximum Drive Output Frequency
×
Parameter 1)
÷
60.
If set to 0000, the drive will enter 40 ms but display 0000.
From 00.10-1000 seconds, this parameter sets the accel time value in 0.1
second increments.
From 1000-1600 seconds, this parameter sets the accel time value in 1
second increments.
