Switchover of the operation mode with
50Hz, 30Hz and 10Hz are not output from RH, RM and RL respectively when they are turned on. ... Why?
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
page 52)
Check for the Pr. 79 setting once again. (Pr. 79 must be set to "0" or "2".) (Refer to page 57)
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)
[FWD (or REV)] is not lit. ... Why?
Check that wiring is correct. Check it again.
Check that "60" is set in Pr. 178 STF terminal function selection (or "61" is set in Pr. 179 STR terminal
