Operating Manual DUM/F6-Servomotors
V20 Edition: 12 March

2019
The motors of the DUM/F6 series are generally designed to meet degree of protection IP65 as specified in DIN EN 60034-5.
See table below for the respective sealing.
Shaft sealing
Degree of
protection User information
Diaphragm seal (standard)
IP64
Exposure to moisture in the shaft and flange area must be kept to a mini-
mum.
Please contact us, if the motor is mounted with the "shaft end
upward“ (IMV3, IMV19, IMV36).
Shaft outlet is not dustproof.
Rotary shaft seal (option)
IP65
Suitable for the installation of non-sealed gear units to seal against oil.
Lubrication of the rotary shaft seal
When using a rotary shaft seal, note that the sealing lip needs to be sufficiently lubricated and cooled with a
high-quality mineral oil such as SAE20 to ensure the proper functioning of the seal. Sufficient lubricant supply
is required for proper heat dissipation.
If the shaft seal is greased, the maximum permissible motor speed may need to be reduced.
Regular regreasing is imperative!
Excessive peripheral speeds destroy the sealing lip and its protective function is no longer guaranteed.
The rated power (rated torque) applies to continuous
operation (duty type S1) at a coolant temperature of
40°C and an altitude of up to 1,000m a.s.l. It is deter-
mined by using defined aluminium test flanges.
If the motor flange is thermally insulated, it is not able
to dissipate the motor heat. This requires a reduction of
the rated motor torque.
At higher temperatures or altitudes, the overload capa-
bility of the motors is reduced (see table opposite).

Surface temperatures of more than 100°C may occur on the motors. Therefore, no temperature-sensitive parts
must be allowed to come into contact or be attached to them.
If the motor is equipped with a separately driven fan, connect the fan properly and check the direction of rota-
tion (arrow on the fan housing). Make sure that the rotation of the fan wheel is not obstructed.
The different cycle frequencies of the electronic converter output stages may require the motor to be derated,
resulting from an increased harmonic content.
