A couple questions on the G2002:

a) servo or stepper ?

b) what is the maximum motor voltage ?

c) what is the maximum motor current ?

d) is there a way to read the machine position after an emergency
shutdown, ie are the encoders powered separately from the motors and is
there a communication link between the PC and the axes position
registers ?
