PURPOSE:To relieve the load of the worker at teaching by deciding the playback speed based on the change amount of a stored position data and the change in a direction data so as to allow a playback data corresponding to the processing accuracy to be inputted. CONSTITUTION:A microprocessor 21 subtracts a value of the address 0 from a value of the address 1 of a table 22 and accesses a frequency table 23 by using the subtracted value as an address. A frequency indication data is stored in advance in the table 23, the processor 21 reads the command frequency corresponding to the displacing amount of a position data, gives it to motor drive sections 19b, 19a via an input/output interface 20 and the drive sections 19a, 19b revise an exciting pattern of motors 18a, 18b by the command frequency. Thus, a proper playback data is inputted by having only to tracing the locus of the tip tool at a natural speed being slow at the minute operating position and fast at a coarse operating position, allowing to relieve remarkably the load of the worker. |
