Forexample, 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 inthe initial setting.By setting "0 (RL)", "1 (RM)", "2 (RH)" in any of Pr.178 to Pr.189 (inputterminal function assignment), the signals can be assigned to otherterminals.(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 thecombination of the RH, RM, RL and REX signals. Set the runningfrequencies in Pr. 24 to Pr. 27, Pr. 232 to Pr. 239. (In the initial valuesetting, speed 4 to speed 15 are unavailable.).⋅ For the terminal used for REX signal input, set "8" in any of Pr. 178 toPr. 189 (input terminal function selection) to assign the function.* When "9999" is set in Pr. 232 Multi-speed setting (speed 8), operation is performed atfrequency set in Pr. 6 when RH, RM and RL are turned off and REX is turned on.148
