Converter
● If operated with a frequency converter, the emitted interference varies in
strength, depending on the design of the converter (type, interference
suppression measures, manufacturer).
● Prevent the limit values stipulated by EN 61000-6-3 for the drive system
(consisting of the machine and converter) from being exceeded.
● You must observe the EMC information from the manufacturer of the converter.
● The most eff ective method of shielding is to conductively connect a shielded
machine supply cable to the metal terminal box of the machine (with a metal
screw con nection) over a large surface area.
● On machines with integrated sensors (e.g. PTC thermistors), disturbance
voltages caused by the converter may occur on the sensor cable.
Balancing
CAUTION
A suitable tool must always be used for fitting and pulling off output elements.
The feather keys are only secured to prevent them from falling out during
transportation.
Please observe the general requirements regarding touch protection measures that
need to be taken for the output elements.
NOTICE
If a machine without an output element is commissioned, the feather keys must be
secured to prevent them from
The rotors are balanced dynamically. The balancing quality corresponds to vibration
severity grade "A" for the complete machine as standard. The optional vibration
severity grad e "B" is indicated on the rating plate.
The declaration regarding the type of featherkey for balancing is generally marked on
the rating plate and optionally on the face of the shaft end.
Desi gnation:
● As a standard measure, balancing is carried out dynamically with a half
featherkey (code "H") in accordance with ISO 8821.
● "F" means bala
● "N" means balancing without a featherkey (optional version).
Note
Measures conforming to ISO 10816 must be taken in order to compensate any offs
between electrical machines and driven machines.
The foundation must be designed according to DIN 40
