Yes it is the weight of the head being carried by the servo.
Do you know if the machine has the Power Failure Detection Module Installed?
Without this module on some machines when the power goes of the spindle will drop anything up to 0.1". This happens because the magnetic brake on the servo clamps down to slowly when the servo loses power.
Watch the position display when you hit Estop and see if the spindle drops. Have someone watch the spindle when the power is shut off at the back of the machine and when the power is turned off at the panel breaker.
If the spindle drops with any of these you need the module, otherwise if you have a power outage during a long job you have probably lost a tool and the part.
An open mind is a virtue...so long as all the common sense has not leaked out.
