Installation : Joint #2
(1) Attach a new motor to the motor flange with bolts (2-M4×10 for the ES series;
4-M5×12 for the EL series).
(2) Mount the waveform generator to the motor shaft with two flat point setscrews (M4
×
6
for the ES series; M5×6 for the EL series). Match the end face of the waveform
generator to the end face of the motor shaft. One of the setscrews should touch the
flat side of the motor shaft perpendicularly. Insert a bush in the other setscrew hole
and tighten the screw. Do not over tighten to avoid damage to the motor shaft.
