(M5 6). Match the end face of the waveform generator to the end face of the motor
shaft. One of the setscrews should touch the flat face in the motor shaft
perpendicularly. Insert a bush into the other setscrew hole and tighten the screw
carefully to avoid damage to the motor shaft.
Between the ES and EL series, the direction in which the waveform generator is
attached is different (See below). ES: The setscrews should be fixed at the end of
the motor shaft; EL: The setscrews should be fixed at the foot of the motor shaft.
