JOG Acceleration Time
JOG Deceleration Time
Default: 10.00
Settings Pr. 01-45 = 0: 0.00–600.00 seconds
Pr. 01-45 = 1: 0.00–6000.0 seconds
Use the acceleration time to determine the time required for the AC motor drive to accelerate
from 0.0 Hz to maximum output frequency (Pr. 01-00). The Deceleration Time is used to
determine the time required for the AC motor drive to decelerate from the Maximum Output
Frequency (Pr. 01-00) down to 0.00Hz.
The acceleration and deceleration time are invalid when using Pr. 01-44 Auto-acceleration and
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.
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.
JOG Frequency
Default: 6.0
Settings 0.0–1500.0 Hz
You can use both the external terminal JOG and F1 key on the keypad KPC-CC01 to set the JOG
function. When the JOG command is ON, the AC motor drive accelerates from 0 Hz to the JOG
frequency (Pr. 01-22). When the JOG command is OFF, the AC motor drive decelerates from the
JOG frequency to stop. The JOG acceleration and deceleration time (Pr. 01-20, Pr. 01-21) are the
time to accelerate from 0.0Hz to the JOG frequency (Pr. 01-22). You cannot execute the JOG
command when the AC motor drive is running. When the JOG command is executing, other
operation commands are invalid.
