Name Description
A trip will occur if brake ON/OFF cannot
be confirmed within the Brake
Confirmation Wait Time (b124) after the
Inverter has issued a brake release
output, provided that the Brake Control
function is enabled (b120 = 01).

If an overload occurs in the extremely
low speed range of 0.2 Hz or below, it
will be detected by the built-in
electronic thermal of the Inverter and a
trip will occur. (However, the error
history may indicate a high frequency).
The Inverter is tripped when there is an
error or broken line for communications
with an externally connected Operator
(optional).
A trip will occur upon timeout if the
communication error selection is set to
tripping (C076 = 00).
−
This error is reported by an optional
board.
A timeout occurred in communications
between the Inverter and optional
board, and the Inverter was tripped.
