8.2.2 Installing the SERVOPACK

Align the shaft of the Servomotor with that of the equipment to be controlled. When connecting
couplings, be careful not to apply any impact to the shaft or excessive force on bearings. Install
the Servomotor so that alignment accuracy falls within the range shown below. If the shafts are
not aligned properly, vibration will occur, resulting in damage to the bearings.
Measure this distance at four different positions on the circumference. The
difference between the maximum and minimum measurements must be
0.03 mm (0.0012 in) or less. (Turn together with couplings.)

Figure 8.2 Alignment
Do not apply any excessive thrust load or radial load to the AC Servomotor. When installing
gears, couplings, pulleys, etc., be careful not to apply any impact to the shaft or excessive force
on bearings. Mechanical shock to the shaft end must be less than 490m/s2 (1607.61 ft/s2 50 G)
Design the mechanical system so that thrust load and radial load applied to the servomotor shaft
end during operation falls within the range shown in Table 3.1.
Z—Series SGDB SERVOPACKS are base-mounted servo controllers.
Install the SERVOPACK according to the following instructions, since faulty installation may
cause malfunction.
