„ Permissible moment load of the Harmonic geared type
When installing an arm or table on the flange surface, calculate the moment load using the formula below if the flange
surface receives any eccentric load. The moment load should not exceed the permissible value specified in the table.
Moment load: M [N·m (oz-in)] = F × L

Installing the driver
Mount the driver to a 35 mm (1.38 in.) width DIN rail.
When two or more drivers are to be installed side by side, provide 10 mm
(0.39 in.) and 50 mm (1.97 in.) clearances in the horizontal and vertical
directions, respectively.
Note
• Install the driver in an enclosure whose pollution degree is 2
or better environment, or whose degree of protection is IP54
minimum.
• Do not install any equipment that generates a large amount
of heat or noise near the driver.
• Do not install the driver underneath the controller or other
equipment vulnerable to heat.
• Check ventilation if the ambient temperature of the driver
exceeds 50 °C (122 °F).
• Be sure to install the driver vertically (vertical position).
1. Pull down the DIN lever of the driver and lock it. Hang the hook at the rear to the DIN rail.
2. Hold the driver to the DIN rail, and push up the DIN lever to secure.
3. Secure both sides of the driver using end plates.
