Possible faults:
●
50 Hz for the RH, 30 Hz for the RL and 10 Hz 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" = "1", Pr. 182 "RH terminal function selection" = "2" and Pr. 59 "Remote function
selection" = "0" (all are initial values).
●
RUN lamp is not lit.
– Check that wiring is correct.
– Check for the Pr. 79 setting once again. (Pr. 79 must be set to "4".) (Refer to section 5.1.6.)
