error detection time  Set the time until the detection of [AL. 8D.1 CC-Link IE communication error 1] or [AL. 8D.6 CC-Link IE
communication error 3]. When the parameter is set to "0", the detection time varies depending on the setting
value of [Pr. PN03] as shown in the following table.
When [Pr. PD41] is set to "_ 1 _ _" or "1 _ _ _", increasing the parameter setting value may cause a collision
at the occurrence of a communication error. Remember this point when changing the setting value.
Setting range: 0 to 1000

communication _ _ _ x Station-specific mode setting
Select the motion mode for connection with a simple motion module or the I/O mode for connection with a
master/local module.
0: Motion mode
1: I/O mode
For the correspondence with the control modes, refer to [Pr. PA01].
The setting of this digit is used by servo amplifier with software version A1 or later. 0h

Set the network number of the servo amplifier.
When "0" is selected, use the network number transmitted from the master station.

error detection
frequency setting

Set the frequency of communication error detection until the detection of [AL. 8D.7 CC-Link IE
communication error 4] or [AL. 8D.8 CC-Link IE communication error 5]. When the parameter is set to "0", the
frequency will be 8%.
Setting range: 0 to 100 0 [%]

Function selection
N-1 _ _ _ x Communication error alarm history writing selection
Select whether [AL. 8D.1 CC-Link IE communication error 1] and [AL. 8D.2 CC-Link IE communication error
2] are recorded in the alarm history at their occurrence.
0: Disabled
1: Enabled
When the parameter is set to "1", follow the correct procedure for turning off the power to prevent the
occurrence of [AL. 8D.1] or [AL. 8D.2] at power supply shut-off (network disconnection). For details, refer to
[Pr. PN06 Communication error detection method selection]. 0h
_ _ x _ Communication error alarm detection method selection
Select the condition for detecting the occurrences of [AL. 8D.1 CC-Link IE communication error 1] and [AL.
8D.2 CC-Link IE communication error 2].
0: Detected only at servo-on.
1: Continuously detected.
When the parameter is set to "0", [AL. 8D.1] and [AL. 8D.2] are detected only at the input of servo-on
command. When turning off the power, set the servo amplifier to the servo-off status with commands and
then turn off the power.
When the parameter is set to "1", [AL. 8D.1] and [AL. 8D.2] are continuously detected while data is being
linked. When turning off the power, turn off the servo amplifier first and then the controller. 0h
