Remarks
Transmission Delay Time
*6
OK Sets the transmission delay time that is a parameter used to cal-
culate the I/O refresh time.
Selects the transmission delay time for each PDO communica-
tions cycle from the following values.
•
Estimated result from network configuration setting on Sysmac
Studio
•
Calculation result from the measured value in the actual net-
work configuration
*7
Default setting: Estimated result from network configuration set-
ting on Sysmac Studio
Reference Clock Not
al-
low-
ed.
Displays whether the master provides a reference clock.
*8
Exist: The master provides a reference clock.
Not Exist: The master does not provides a reference clock.
Total Cable Length
*9
OK This is the total cable length, including the cable between the
EtherCAT master and a slave and cables between slaves.
Setting range: 1 to (100 × Maximum number of slaves)
*10
Default setting: 1,000 m
Fail-soft Operation Setting OK Selects Stop or Fail-soft operation for communications with all
slaves on the network when the master detects a communica-
tions error (cable disconnection, slave malfunction, etc.).
Default setting: Fail-soft operation
For the operating specifications of the master and slaves with the
Fail-soft Operation Setting when a communications error occurs,
refer to
Errors in the EtherCAT Master Function Module in the
NJ/NX-series Troubleshooting Manual (Cat. No. W503) . For
events that are affected by the Fail-soft Operation Setting, the op-
erating specifications are specified for each set value.
Wait Time for Slave Startup OK Sets the time to wait from the detection of the link on the Ether-
CAT port until all slaves connect the network.
Setting range: 3 to 200 s
Default setting: 30 s
Process data communications start if all slaves are present within
the wait time. If all of the slaves are not present after the wait time
elapses, a
Network Configuration Verification Error (84220000
hex), Network Configuration Verification Error (Slave
Unconnected) (84380000 hex), Network Configuration
Verification Error (Unnecessary Slave Connected) (84320003
hex), Network Configuration Verification Error (Mismatched
Slave) (84330004 hex), or Network Configuration Verification
Error (Incorrect Ring Wiring) (843A0000 hex) event occurs.
When you use a slave that takes time to start, use a longer wait
time setting to prevent errors.
PDO Communications Timeout
Detection Count OK A Process Data Reception Timeout (842B0000 hex) event occurs
if process data (PDO) communications timeouts occur continu-
ously more often than the specified number of times.
Set the value to 2 or higher for a slave that needs to be replaced.
Setting range: 1 to 8
*11
Default setting: 2 errors
