PU operation mode
Basic settings
5 - 44
Possible faults:
●
50Hz for the RH, 30Hz for the RL and 10Hz for the RL are not output when they are turned on.
– Check for the setting of Pr. 4, Pr. 5, and Pr. 6 once again.
– Check for the setting of Pr. 1 "Maximum frequency" and Pr. 2 "Minimum frequency" once
again. (Refer to section 5.1.4.)
– Check that Pr. 180 "RL terminal function selection" = "0", Pr. 181 "RM terminal function
selection" = "2", Pr.182 "RH terminal function selection" and Pr. 59 "Remote function
selection" = "0" (all are initial values).
●
FWD (or REV) lamp is not lit.
– Check that wiring is correct. Check the wiring once again.
– Check for the Pr. 79 setting once again. (Pr. 79 must be set to "4".) (Refer to section 5.1.6.)

Operate the inverter by using multi-speed setting
NOTE
Refer to section 5.3.2 to change the running frequency at each terminal in Pr. 4 "Multi-speed
setting (highspeed)", Pr. 5 "Multi-speed setting (middle speed)", and Pr. 6 "Multi-speed set-
ting (low speed)".
Screen at powering on
The monitor display appears.
Change the Pr. 79 setting to "4".
(Refer to section 4.3.7 for change of the setting.)
Press the start switch FWD or REV to give the
start command. When the frequency command is
not given, it flickers.
Turn on the low speed switch (RL). The output
frequency increases to 10Hz according to Pr. 7
"Acceleration time".
Turn off the low speed switch (RL). The output
frequency decreases to 0Hz according to Pr. 8
"Deceleration time".
Turn off the start switch STOP/RESET.
