The terminal determines three-line control of the AC
drive. For details, see the description of F4-11.
4 Forward JOG (FJOG)
FJOG indicates forward JOG running, while RJOG
indicates reverse JOG running. The JOG frequency,
acceleration time and deceleration time are described
respectively in F8-00, F8-01 and F8-02.
5 Reverse JOG (RJOG)
6 Terminal UP If the frequency is determined by external terminals, the
terminals with the two functions are used as increment
and decrement commands for frequency modication.
When the frequency source is digital setting, they are
used to adjust the frequency.
7 Terminal DOWN
