The CX-Drive can-
not be connected
with the inverter.
The CX-Drive version is not
supported.
To connect the CX-Drive to the 3G3MX2-EV2
Series, use Ver. 2.8 or higher.
P. 3-16
The inverter software number
does not match.
Set the software number of the connected
inverter in the CX-Drive.
P. 3-20
The Modbus mapping endian
function setting is inappropri-
ate.
Set the Modbus Mapping Endian Selection
(P400) to 00 (Big endian).
P. 8-29
The inverter does
not accept parame-
ter settings from the
CX-Drive.
The inverter is in operation.
Stop the inverter and, after the motor falls in a
deceleration-stop state, set the parameters
again. Setting b031 to 10 (Data can be
changed during RUN) enables parameter
settings to be changed even when the
inverter is in operation.
−
The Modbus mapping function
is enabled.
Set the Modbus Mapping Function Selection
(P200) to 00 (Standard Modbus address).
P. 8-24
The brake control
function causes an
Overload protec-
tion alarm (E05).
The inverter is in operation with
the brake force.
Turn OFF the RUN command to the inverter
when the brake is applied. Even under DC
injection braking, an Overload protection
alarm may occur.
P. 6-25
P. 6-50
The brake control
function causes a
Brake error (E36).
The output current does not
reach the set brake release
current value.
Increase the Brake Release Wait Time (b121)
value or decrease the Brake Release Current
(b126).
P. 6-25
P. 6-50
The brake confirmation signal
is not input.
• Correct the wiring for the brake confirmation
signal (44: BOK). Deallocate the brake con-
firmation function from the multi-function
input setting.
• Review the operation sequence so that the
brake confirmation signal (44: BOK) is input
after the brake is released.
• Replace the brake if it is faulty.
P. 6-25
P. 6-50
The brake control
function causes the
load to fall.
The set brake release current is
insufficient.
• Increase the Brake Release Current (b126)
value.
• Set the 1st/2nd Control Method
(A044/A244) to 03 (Sensorless vector con-
trol).
P. 6-25
P. 6-50
The frequency setting for
releasing/forcing the brake is
too low.
Increase the Brake Release Frequency
(b125), Brake Force Frequency (b127), or
Creep Speed Setting (P015) value.
P. 6-25
P. 6-50
The PM motor
rotates during
startup.
The magnetic pole position of
the motor during startup is
incorrect.
Set the PM Motor Starting Method Selection
(H123) to 01 (Initial pole position estimation
enabled).
P. 6-64
The PM motor
causes an Overcur-
rent protection
alarm (E03) during
startup.
The PM motor stalls.
Increase the PM Motor Starting Current
(H117) value.
Or perform adjustments according to 6-8-6
Adjustment of PM Motor Mode Settings on
page 6-64.
P. 6-64
The load too heavy.
Reduce the load. Or increase the accelera-
tion/deceleration time.
P. 5-32
