Frequency setting by external terminals
4
(2) Multi-speed setting higher than speed 4
(Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
⋅
Frequency from speed 4 to speed 15 can be set according to the combination of the RH, RM, RL and REX signals. Set
the running frequencies in
Pr. 24 to Pr. 27, Pr. 232 to Pr. 239
. (In the initial value setting, speed 4 to speed 15 are invalid.)
⋅
For the terminal used for REX signal input, set "8" in any of
Pr. 178 to Pr. 186
to assign the function.
*
When "9999" is set in
Pr.232 Multi-speed setting (speed 8)
, operation is performed at frequency set in
Pr.6
when RH, RM and RL are turned off and
REX is turned on.
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 160
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 input compensation selection
.
CAUTION
⋅
The RH, RM, RL, REX signals can be assigned to the input terminal using any of
Pr. 178 to Pr. 189 (input terminal function
selection)
. Changing the terminal assignment using
Pr. 178 to Pr. 189 (input terminal function selection)
may affect the other
functions. Make setting after confirming the function of each terminal.
