Frequency setting by external terminals
Operation is performed at the frequency set in Pr. 4 when the RH signal turns on, Pr. 5 when the
RM signal turns on, and Pr. 6 when the RL signal turns on.
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 unavailable.)

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.
NOTES In the initial setting, if two or three speeds are simultaneously selected, priority is given to
the set frequency of the lower signal. For example, when the RH and RM signals turn on, the
RM signal (Pr. 5) has a higher priority.
The RH, RM, RL signals are assigned to the terminal RH, RM, RL in the initial setting. By
setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr. 178 to Pr. 189 "Input terminal function assig-
nment", you can assign the signals to other terminals.
For the terminal used for REX signal input, set "8" in any of Pr. 178 to Pr. 186 to assign the
function.
