12.1
Connection cables
12.1
For the connection from the servo drive to the machine or plant,
there are different connection cables. For information on connecting
a servo drive to a machine or system, refer to the chapter: Electrical
installation.
12.2
Shaft sealing ring
12.2
The FKM radial shaft sealing ring serves to seal against splash wa-
ter and to protect the servo drive shaft against the ingress of dust or
dirt. This increases the degree of protection of the shaft feedthrough
to IP65.
The radial shaft-sealing ring can be replaced at any time. Please
note, however, that the exchange may lead to a reduction in the
nominal values.
12.3
Gear unit
Axial load due to thermal expansion of the motor shaft
To avoid displacement of the motor shaft at high temperatures, use
couplings as length compensation.
Directly mounted bevel gears or helical gear wheels can exceed
the axial load of the floating bearing on the shaft end A.
A gear unit serves to transmit a moment of force or a torque and is
used on the servo drive as an output element. Information on flange
sizes for combinations of servo drive and gear unit can be found in
the chapter: Type key.
