Settings
 The acceleration time determines the time required for the AC motor drive to ramp from 0.00 Hz
to the maximum operation frequency (Pr.01-00). The deceleration time determines the time
required for the AC motor drive to decelerate from the maximum operation frequency (Pr.01-00)
down to 0.00 Hz.
 The acceleration and deceleration time are invalid when using Pr.01-44 Auto-acceleration and
Auto-deceleration Setting.
 Select the Acceleration/Deceleration Time 1, 2, 3, 4 with the multi-function input terminal
settings. The defaults are Acceleration Time 1 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 drive's
protection function (Pr.06-03 Over-current Stall Prevention during Acceleration or Pr.06-01 Over-
voltage Stall Prevention), and the actual acceleration and deceleration time are longer than this
setting.
 Note that setting the acceleration time too short may cause motor damage or trigger drive
protection due to over-current during the drive's acceleration.
 Note that setting the deceleration time too short may cause motor damage or trigger drive
protection due to over-current during the drive's deceleration or over-voltage.
 Use suitable brake resistors (refer to Chapter 07 Optional Accessories) to decelerate in a short
time and prevent over-voltage.
 When you enable Pr.01-24–Pr.01-27 (S-curve acceleration and deceleration begin and arrival
time), the actual acceleration and deceleration time are longer than the setting.
Pr.01-45 = 0: 0.00–600.00 sec.
Pr.01-45 = 1: 0.0–6000.0 sec.
