Motion control setting and Motion module cannot communicate
When the motion control setting and Motion module cannot communicate in the PLCopen Motion control FB mode, check the
following.
Check item
Is a value less than Is the number of device stations in the network
125 s set in the configuration settings exceeding the referential number

MR-J5(W)-G cannot connect
When MR-J5(W)-G cannot connect, check the following items.
Check item
Has "Network parameter error (error code: 2221H)" occurred?
Has the MR-J5(W)-G 7-segment LED
*1
display stopped as shown below?
When in Simple Motion mode, has
the MR-J5(W)-G 7-segment LED
*1
display stopped as shown below?
*1 For MR-J5W-G, the number of characters displayed on the 7-segment LED is different.
Has a moderate error/major error
occurred in the Motion module?
When using multi-axis servo
amplifiers, has the control axis
deactivation switch of the DIP switch
(SW3) been set to ON?
In network configuration settings, has
the number of extension modules
connected to the multi-axis servo
amplifier been changed from the
default settings?
Has "Motion control station setting
error (error code: 1C4BH)" occurred
in the Motion module?
Action
• Reduce the number of device stations set in the network configuration.
• Increase the setting value of the communication period interval setting.
Action
Check the event history, and confirm the relevant parameter that corresponds
with the parameter No. found in detailed information.
• When setting a disabled axis in a multi-axis servo amplifier, set the disabled
axes from the latter axis.
• In Network configuration settings, change the number of extension modules
that are connected to the corresponding multi-axis servo amplifier so that
they match the number of axes not set to Axis Disabled minus "1".
<Example> When setting only 1 axis from A to C axis of MR-J5W3-G to axis
disabled.
• Control axis deactivation switch (SW3) setting:
Set only C axis to axis disabled (SW3-4 to ON).
• Network configuration setting:
Add or delete MRJ5W3-G_BC_Axis so that there is only 1 MRJ5W3-
G_BC_Axis that is connected to MR-J5W3-G.
• In network configuration settings, allocate the device station set to the
Motion control station to an axis in Simple Motion settings.
• Set the device stations with no allocations to any axes to a general station
(no check next to Motion control station setting) in network configuration
settings.
