REMARKS
⋅
The priorities of the frequency commands by the external signals are
"jog operation > multi-speed operation > terminal 4 analog input >
terminal 2 analog input". (Refer to
page 282
for the frequency
command by analog input)
⋅
Valid in external operation mode or PU/external combined operation
mode (
Pr. 79
= "3" or "4").
⋅
Multi-speed parameters can also be set in the PU or external
operation mode.
⋅
Pr. 24 to Pr. 27
and
Pr. 232 to Pr. 239
settings have no priority between them.
⋅
When a value other than “0” is set in
Pr. 59 Remote function selection
,
the RH, RM and RL signals are used as the remote setting signals
and the multi-speed setting becomes invalid.
⋅
When making analog input compensation, set "1" in
Pr. 28 Multi-speed
