1.2.3 Installing the Servo Amplifier

(1) Install the servo amplifier vertically to the ground so that the

characters (see the arrow in the figure on the right) on the

front panel of the servo amplifier is horizontal.

Use M4 screws with length between 12 and 20 mm for the

mounting to the control panel.

Use screws together with plane washers or spring lock

washers or use 3-piece sems screw to avoid looseness.

When using plane washers, select the finished round type

(large size with φ9 mm).

(2) Some parts of the servo amplifier generate heat during operation.

Cool the surroundings if the servo amplifier is installed inside the control panel.

Natural convection, air

tight structure

(totally enclosed type)

(3) To install two or more servo amplifiers in the same control panel, the following shall be taken into

consideration.

Arrange transverse alignment in principle. The RYT type servo amplifier can be installed side by

side closely. If servo amplifiers are installed completely side by side closely, operate them at the 80

[%ED] rating.

If the ambient temperature is 45 [°C] or lower in the close installation state, 100 [%ED] can be

If there is a clearance of 5 [mm] or over between adjacent servo amplifiers, there is no limitation in

the operation frequency.
