 When the drive starts, it operates from the minimum output frequency (Pr.01-07) and accelerates
to the setting frequency. It is not limited by the lower output frequency settings.
 Use the output frequency upper and lower limit settings to prevent operator misuse, overheating
caused by operating at a too low frequency, or damage caused by excessive speed.
 If the output frequency upper limit setting is 50 Hz and the frequency setting is 60 Hz, the
maximum output frequency is 50 Hz.
 If the output frequency lower limit setting is 10 Hz and the minimum operation frequency setting
(Pr.01-07) is 1.5 Hz, the drive operates at 10 Hz when the frequency command is greater than
Pr.01-07 and less than 10 Hz. If the frequency command is less than Pr.01-07, the drive stays in
ready status with no output.
 If the frequency output upper limit is 60 Hz and the frequency setting is also 60 Hz, only the
Frequency command is limited in 60 Hz. The actual frequency output may exceed 60 Hz if the
drive starts the slip compensation function.

Pr.01-45 = 1: 0.0–6000.0 sec.
 Use the acceleration time to determine the time required for the AC motor drive to accelerate
from 0 Hz to maximum output frequency (Pr.01-00).
 The acceleration and deceleration time are invalid when using Pr.01-44 Auto-acceleration and
Auto-deceleration Setting.
 Select the acceleration and deceleration time 1, 2, 3, and 4 with the multi-function input terminals
settings. The defaults are acceleration and deceleration time 1. With the enabled torque limits
and stall prevention functions, the actual acceleration and deceleration time are longer than the
above action time.
 Note that setting the acceleration and deceleration time too short may trigger the protection
function (Pr.06-03 Over-current Stall Prevention during Acceleration or Pr.06-01 Over-voltage
Stall Prevention).
 Note that setting the acceleration time too short may cause motor damage or trigger drive
protection due to over-current during acceleration.
 Note that setting the deceleration time too short may cause motor damage or trigger drive
protection due to over-current during deceleration or over-voltage.
