Frequency setting by external terminals
Forward
rotation
NOTES 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 section 6.15
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.
The RH, RM, RL, REX signals can be assigned to the input terminal using any of Pr. 178 to
Pr. 182. When terminal assignment is changed, the other functions may be affected. Please
make setting after confirming the function of each terminal.
