12 Descriptions of Parameter Settings | VFD-ED
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.
When there is a large opposing torque and inertial torque for the load, and the acceleration and
deceleration time settings are less than the necessary value, then they enable the torque limit and stall
prevention functions. When this happens, the actual acceleration and deceleration time are longer than
the settings.

You can use both the external terminal JOG and the JOG key on the keypad. When the JOG command is
ON, the AC motor drive accelerates from the fourth output voltage setting (Pr.01-07) to the JOG frequency
(Pr.01-22). When the JOG command is OFF, the AC motor drive decelerates from the JOG frequency to
zero. The Acceleration and Deceleration time are set by these parameters (Pr.01-20, Pr.01-21).
You cannot execute the JOG command when the AC motor drive is running. When the JOG command is
running, other operation commands are invalid except the Forward and Reverse commands.
