Out of Estop.. BUT

I've only one axis hooked up with the computer
for now.It is something like this:

Regenerative Resistor
|
STG2 --> AC AMP-->Thermal Relay--> AC Servo Motor w/ encoder

Thermal relay is not connected with GND

Now few more problems turned out.
1)Motor rotates very slightly in a jerky motion simultaneously
giving a high pitched sound. I tried the zero setting on
the amplifier drive. It helps to slow down the motion but
didn't removed it completly.
I think thermal relay has something to do with it.
I'm not sure of Thermal relay function.

I ran EMC , X axis keeps ticking in EMC
I got Machine ON and it gave me the following error message
"Error:Axis 0 following error"

2)I stopped the motor supply but kept the
encoder running.I started EMC , got machine ON.
First i rotated the motor shaft slowly by hand
(on which the encoder is mounted) , EMC started giving me the
encoder ticks on X-Axis.But after I increased the rotation speed
slightly
the encoder reading stopped.
