axis index error，Z motor rotates when jog moving X......

LinuxCNC+3 sets of EtherCAT servo
now I met an issue: axis index error
I installed the EtherCAT servo from X to Z in EtherCAT topology, but when I jog moving X axis, Z motor rotates,  jog moving Z axis, X motor rotates
I checked the XXX.ini, XXX.hal and XXX.xml, can't found the reason, can you advice me how to solve it?

Sounds like your physical wiring is mixed up. Just debug one slve at a time.
You could try changing your ini file to 
COORDINATES = ZYX

Thank you for your timely reply.
Yes, my mistake, it is physical wiring issue.
I use Xinje Ethercat servo(Type: DS5C1K-20P4-PTA), its IN port on the down side while OUT port on the up side. I regarded upside port(OUT port) as IN port wrongly, it works in weird ways.

besides, I also changed the COORDINATES as your said, but there is not any differences before and after i correct the wiring, XZ axis not swaps.
XXX.ini file
[TRAJ]
COORDINATES = X Y Z or Z Y X
LINEAR_UNITS = mm
ANGULAR_UNITS = degree

Just adding my 5 cents. I also had the same issue (3 axis machine with the Z-axis actually moving when I jogged the X-axis on the PC).

I'm using the leadshine CS3E-D1008 and in/out was connected correctly. But the PC was connected to the drive with slave address 2. Motors are wired with slave 0 connected to the X motor, slave 1 to Y motor and slave 2 to Z motor.  This cause X/Z to be swapped in linuxcnc.

Ethercat is not ethernet. Order of connecting DOES really matter! See attached picture for correct wiring of 3 ethercat drives for an XYZ machine.
