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.

JOG Frequency
Factory Setting: 6.0
Settings 0.0~1500.0 Hz
 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.
