Tips/FAQ/Troubleshooting
E104 Position control
range error
When the current position counter exceeds the
position control ranges for normal/reverse rotation in
the setting of [AE-52] position range (normal) or
[AE-54] position range (reverse), the inverter turns
OFF its output and displays the error.

E105 Speed deviation error
When the deviation between the frequency command
and the feedback speed exceeds the [bb-83] speed
deviation error detection level setting, the inverter
judges it as an error. If “01: Error" is specified for
[bb-82] Operation for speed deviation error, the
inverter turns ON the output terminal function 041
[DSE] with a speed deviation error, turns OFF the
inverter output, and displays this error.

Estimated cause(s)

Exemplar measures to be taken
Error occurred
during operation.
• Recheck the setting of
electronic gear.
• Re-examination of operation condition or correction of load condition
may improve the situation.
• A slip occurs due to
improper encoder
setting.
• Check the encoder mounting state. If any, re-examine factors for
slipping.
• Improper electronic gear
setting
• Recheck the setting of electronic gear.
• Improper encoder setting • Check the setting of encoder constant and the like.
