Functions
* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.
•Does not accept any frequency reference beyond the upper/lower limits.
•Set the upper limit first. Make sure that the upper limit (A061/A261) is larger than the lower limit
(A062/A262).
•Make sure that the upper and lower limiter settings do not exceed the maximum frequency (A004/
A204/A304).
•Make sure that the output frequency (F001) and multi-step speeds 1 to 15 (A021 to A035) are not
lower than the lower limit setting and not higher than the upper limit setting.
•Neither limit works if set to 0 Hz.
•Disabled when the 3rd control is selected.
When Using O-L and OI-L
When Using O2-L
(a) When the RUN command is set to the terminal (A002: 01)
(a) When the RUN command is set to the Digital Operator (A002: 02)
• Once the lower limit is set, the Inverter outputs the
frequency (A062) set for the lower limit, if 0 V (4 mA)
is input to the frequency reference.

• When the lower limit is used for the O2 input, the
rotation at 0 V is fixed to A062 for either forward or
reverse rotation, as described below.
