01 - 19 Decel. Time 4
01 - 20 JOG Acceleration Time
01 - 21 JOG Deceleration Time
Settings
• The Acceleration Time is to determine the length of time required for the VFD to ramp from 0.0 Hz to Maximum Output
Frequency (Pr.01-00). The Deceleration Time is to determine the length of time required for an VFD to decrease from
Maximum Output Frequency (Pr.01-00) to 0.00Hz.
• The Acceleration/Deceleration Time is invalid when using Pr.01-36 Optimal 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 enabling torque limits and stalls prevention function, actual accel./decel. time will be longer than the above action time.
• Please note that it may trigger the protection function (Pr.06-02 Over-current Stall Prevention during Acceleration or Pr.06-01
Over-voltage Stall Prevention) when the 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.
• Please note that it may cause motor damage or drive protection enabled due to over current during deceleration or over-
voltage when the setting of deceleration time is too short.
• It can use suitable brake resistor (see Chapter 06 Accessories) to decelerate in a short time and prevent over-voltage.
• When enabling Pr.01-24~Pr.01-27, the actual accel./decel. time will be longer than the setting.
01 - 22 JOG Frequency (JOG)
Settings
• Both external terminal JOG and key "F1" on the keypad can be used. When the jog command is ON, the VFD will accelerate
from 0Hz to jog frequency (Pr.01-22). When the jog command is OFF, the VFD will decelerate from Jog Frequency to zero.
The Jog Accel./Decel. time (Pr.01-20, Pr.01-21) is the time that accelerates from 0.0Hz to Pr.01-22 JOG Frequency.
• The JOG command can't be executed when the VFD is running. In the same way, when the JOG command is executing, other
operation commands are invalid except forward/reverse commands and STOP key on the digital keypad.
• The optional keypad doesn't support JOG function.
