JOG Acceleration Time
JOG Deceleration Time
Factory Setting: 10.00 / 10.0
Settings Pr. 01-45 = 0: 0.00~600.00 sec.
Pr. 01-45 = 1: 0.0~6000.0 sec.
The acceleration time is used to determine the time required for the AC motor drive to accelerate
from 0 Hz to maximum output frequency (Pr. 01-00).
The acceleration / deceleration time is invalid when using Pr. 01-44 Auto acceleration /
deceleration setting.
The acceleration / deceleration time 1, 2, 3, 4 are selected according to the multi-function input
terminals settings. The factory settings are accel. / decel. time 1.
When enable torque limits and stalls prevention function, the actual accel. / decel. time will be
longer than the above action time.
Please note that it may trigger the protection function (Pr. 06-03 Over-current stall prevention
during acceleration or Pr. 06-01 Over-voltage stall prevention) when setting of accel. / decel. time
is too short.
Please note that it may cause motor damage or drive protection enabled due to over current
during acceleration when the setting of acceleration time is too short.
Use suitable brake resistor (please refer to Chapter 07 Optional accessories) to decelerate in a
short time and prevent over-voltage.
When enable Pr. 01-24 ~ Pr. 01-27 (S-curve accel. / decel. begin and arrival time) , the actual
accel. / decel. time will be longer than the setting.

Both external terminal JOG and key “F1” on the keypad KPC-CC01 (optional) can be used to set
JOG function. When the JOG command is ON, the AC motor drive will accelerate from 0 Hz to
JOG frequency (Pr. 01-22). When JOG command is OFF, the AC motor drive will decelerate from
Jog frequency to stop. The JOG accel. / decel. time (Pr. 01-20, Pr. 01-21) is the time that
accelerates from 0.0 Hz to JOG frequency (Pr. 01-22). The JOG command cannot be executed
when the AC motor drive is running. In the same way, when the JOG command is executing,
other operation commands are invalid.
