To provide a servomotor and encoder diagnostic apparatus to discriminate whether a encoder used for a servomotor and a detection of the rotation number of servomotor is normal or abnormal. The servomotor and encoder diagnostic apparatus consists of motor power supply part encoder power supply part, wave form fixing part(101)(102), control part(200), channel selection part(300), counting part(400), indication part(100). The motor power supply part is to operate the servomotor. The encoder power supply part is to operate the encoder. The wave form fixing part(101)(102) fixes multiple channel signals to the wave forms of stable signal. The control part(200) is to output count up/down signal and channel selection signal according to the output signals from the wave form fixing part. The channel selection part(300) selects and outputs a channel signal among the multiple signals, receiving the channel select signal. The counting part(400) provides numerous counter to proceed up-count or down-count according to the count up/down signal. The indication part(100) furnishes a multitude of indication components to indicate a counted value, receiving the output of counting part. Thereby, it is possible to easily test the servomotor and encoder without the necessity of taking the equipment to pieces, and to provide high confidence for the equipment by reduction of downtime in the equipment and exact monitoring of rotation number in the servomotor.
