[etherlab-users] Problem of state machine on OMRON Servo Driver (R88D-KN04H-ECT)

I get stuck in changing state machine to SAFEOP or OP, and my EtherCAT 
slave is OMRON G5 Servo Driver. I run EtherCAT Master via RTL8111, and 
had already install Realtek driver.  First, I download 0x0006 to 0x6040 
and 0x08 to 0x6060, it follows CiA402 Drive Profile in OMRON manual. 
However, when I type "ethercat state -p0 SAFEOP", the slave display Err 
No. 90 (Communications Setting Error).

Here is my error message:

[ 9897.670992] EtherCAT 0: Master debug level set to 1.

"Synchronization not supported".
[ 9900.353997] EtherCAT 0-0: Acknowledged state PREOP.

Currently, I can enter operational mode with TwinCAT via omron's xml. I 
see one point in this xml file, that is

_/*<Behavior StartToSafeopNoSync="true" />*/_

What is the "StartToSafeopNoSync" means? Where can I set it in EtherCAT 
Master? Any help is appreciated.
