A trigger signal generating device 6 is proposed which can output the trigger signal with high accuracy that gives instructions on operation to the external device 5 operated in synchronization with the servo motor 1. The trigger signal generating device 6 includes a timer setting time calculating portion 63 for calculating a timer setting time by subtracting a servo side delay time and an external device side delay time from a time required until the external device 5 arrives at an operation starting position calculated by a position information of the servo motor and a trigger signal outputting portion 64 for outputting a trigger signal based on the timer setting time, wherein the servo side delay time is defined to be a time period from a time when sampling by the position detecting device starts to a time when the calculation of the timer setting time for generating the trigger signal is completed and the external device side delay time is defined to be a time period from a time when the trigger signal is outputted to a time when the external device starts operation. |
