I have a 2nd hand HITEC-TURN HT20, Serial N°22245, Constructed 14/10/1986, which I bought recently. As it didn’t work since long time, it lost all data table. With the help of friend I found some of them. But the data specific to “HITACHI”, DATA TABLE, DATA CONTROL, DATA N° D0000-D0002-D0010-D0018-D0026-D0034-D0042-D0050-D0058-D0066-D0074. All of this parameters contain 7 Bits. This DATA concern spindle speeds and tool post rotation.
And the DATA for PC counter and PC keep relay.
Please, If anybody have this type of machine, help me please.
