We had this issue on 2 of these machines. We found that when you put the remote handwheel back on the machine the magents cause it to slap on causing a partial e-stop. To correct this press the e-stop on the remote hand wheel and reset it. Then hold MF1 and reset at the same time till the machine comes out of e-stop. We had both of the remote hand wheels replaced and still the same problem. Just got to be gental putting the remote back on the machine.
