Brake error 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).
E36.
 Is the brake ON/OFF
function working?
→Check the brake.
Is the set time for b124 too
short?
→Increase b124 .
Has the brake confirmation
signal been input?
→Check the wiring.

Overload
protection in a
low speed
range
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).
E38.
 Is the load too large?
→Decrease the load rate.
−
Poor Digital
Operator
connection
A trip will occur upon error in the
communication with, or disconnection
of, the external Digital Operator or LCD
Operator.
E40.  Is there any communication
error?
→Check/replace the
cable.
(Note that if b165 is set
to "02," this error will
not be detected).
−
Modbus
communication
(Modbus-RTU)
error
A trip will occur upon timeout if the
communication error selection is set to
tripping (C076 = 00).
E41.  Is the communication
speed correct?
→Check the setting.
Is the wiring distance
appropriate?
→Check the
communication wiring.
Has disconnection
