You can use both the external terminal JOG and F1 key on the optional keypad KPC-CC01 (optional) 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 0.00 Hz 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.

This function does not require the external terminal switching function; it switches the acceleration and deceleration

time automatically according to the Pr.01-23 setting. If you set the external terminal, the external terminal has

priority over Pr.01.23.

When using this function, set the S-curve acceleration time to 0 if the fourth acceleration time is short.

If Pr.01-02=10 s, Pr. 01-18=6 s, then the acceleration time is 3 s for 0 to 40 Hz and 5 s for 40 to 80 Hz.

If Pr.01-13=8 s, Pr. 01-19=2 s, then the deceleration time is 4 s for 80 to 40 Hz and 1 s for 40 to 0 Hz.
