PURPOSE:To have high precision location by determining the lost motion amount according to the reverse direction locational amount commanded by an NC device, and by performing correction with the determined lost motion amount. CONSTITUTION:When a location command is given (Step 1), judgement is made whether it is a reverse direction command. In this case of a regular direction command, jump is made to Step 7 followed by implementation of regular direction location. In the case of a reverse direction command, the location amount is made sure (Step 3), and the lost motion amount corresponding to the locational amount in the reverse direction is read (Step 4) from a file (Step 5). The locational command value is corrected (Step 6) with the read lost motion amount, and reverse direction location is implemented (Step 7) with the corrected location command value.
