Note
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 / IEC 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 effective method of shielding is to conductively connect a shielded
machine supply cable to the metal terminal box of the machine (with a metal
screw connection) 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.
5.3 Balancing
CAUTION
Safety precautions
● The general touch protection measures for drive output elements must be
observed.
● Output elements may only be attached or withdrawn using the correct
equipment.
● The feather keys are only secured against falling out during shipping. If you
commission a machine without an output element, the feather keys must be
secured to prevent them from being thrown out.
The rotors are balanced dynamically. The balancing quality corresponds to vibration
severity grade "A" for the complete machine as standard. The optional vibration
severity grade "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.
Designation:
● As a standard measure, balancing is carried out dynamically with a half
featherkey (code "H") in accordance with ISO 8821.
● "F" means balancing with a whole featherkey (optional version).
● "N" means balancing without a featherkey (optional version).
