<p>When a program command read from a machining program is an auxiliary command, a command associated with the auxiliary command is transmitted. Monitoring of reception of a completion signal corresponding to the command is started. When the completion signal is not received, and when the auxiliary command is a command indicating the unnecessity of waiting to receive the completion signal, determination is made as to whether or not a condition for ending the monitoring of the completion signal corresponding to the auxiliary command is satisfied without receiving the completion signal. When the condition is satisfied, an error process is executed to end the execution of the machining program.</p> |
