Installation/Fitting

5.4 Preparation for Installation

The following preparations must be made to allow the
servomotors to be installed reliably and effectively.
•
Provide a suitable mounting arrangement. The
mounting arrangement depends on the design,
weight and torque of the servomotor.
•
Seat the flange flush against the mounting
surface before fixing the servomotor.
5 5
Misalignment shortens the life of the bearing and
the coupling components and reduces heat
transfer from the motor.
•
Always fit couplings and other transfer
components in accordance with regulations.
•
Provide contact protection if hot surfaces (100 °C)
can be expected during operation.

5.5 Mechanical Installation

5.5.1 Installation and Space Requirements

In addition to its own dimensions, the servomotor only
needs space for the hybrid cable.
The amount of space necessary for installation depends on
the tool that is used.
Illustration 5.2 Required Space

5.5.2 Installation Aids and Tools Required

For installation the tool or tools corresponding to the
fixing screws is needed. The fixing screws are not included
with the servomotor.
With each motor, Danfoss supplies a specially designed
tool for connecting the hybrid cable. The hybrid cable
connector can be tightened quickly and correctly with the
aid of this tool.

5.5.3 Tightening Torques

See Table 5.1 for tightening torque values for the fixing
screws. Always tighten the fixing screws uniformly and
crosswise.

5.5.4 Fitting Instructions

Clamping
Observe the following fitting instructions to ensure reliable
and effective fitting of the servomotor.

Coupling
Use a conventional clamping set to couple the motor shaft
to the machine unit.
NOTE
Do not machine the shaft.
Do not use the servomotor if the shaft does not match the
coupling arrangement.

Check the counterface of the motor mount.
- It must have sufficient heat dispersion
capacity; an unpainted surface is
recommended.
Remove the protective end cap from the shaft.
Fix the servomotor with four screws using the
four mounting holes provided for this purpose in
the machine unit.
- Always use the designated mounting
holes in the mounting flange to fix the
motor.
- Do not modify the mounting holes.
- Always use all four mounting holes. The
motor may run unevenly if fewer
mounting holes are used.
