5.3.3

Error handling procedure

(1) Prevention of reverse rotation <When the prevention of reverse rotation is valid>
Follow the flowchart on 5.1.3 When the motor does not start to check that ON signals of STR and
high speed RH are input using FR Configurator2. Change D020 (Pr.78) (Reverse rotation
prevention selection) to the initial value "0".
(2) Maximum frequency setting
Follow the flowchart on 5.1.5 When the motor speed does not become the set speed to check
that the output frequency does not match with the command using FR Configurator2. Change
H400 (Pr.1) (Maximum frequency setting) to "120 Hz".
(3) E.OHT display <External thermal relay operation>
Change T708 (Pr.186) (CS terminal function selection) to "6" (automatic restart after
instantaneous power failure selection) and close the CS - SD terminal.
(4) E.OPT display <Option fault>
Change E300 (Pr.30) (Regenerative function selection) to "0" (built-in brake).
(5) E.PUE display <PU disconnection>
Return PU to the original position.
(6) E.CDO display <Output current detection value exceeded>
1) Use FR Configurator2 to check the output current when the output current detection value is
exceeded.
2) Change M464 (Pr.167) (Output current detection operation selection) to the initial value "0"
(continuous operation when output current detection value exceeded).
3) Change M460 (Pr.150) (Output current detection level) to the initial value "150%".
