External operation
Possible faults:
●
The EXT lamp is not lit even when the PU/EXT key is pressed.
– Switchover of the operation mode with is valid when Pr. 79 = 0 (initial value).
● 50 Hz, 30 Hz and 10 Hz are not output from RH, RM and RL respectively 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 for the Pr. 79 setting once again. (Pr. 79 must be set to "0" or "2".) (Refer to section 5.1.6.)
– 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.)
● The RUN lamp is not lit.
– Check that wiring is correct.
– Check that "60" is set in Pr. 178 "STF terminal function selection" (or "61" is set in Pr. 179 "STR
