7.2 Encoders 
 
WARNING 
 
Incorrect commutation can result in uncontrolled motor movements. 
When the encoder is replaced, make sure that the commutation setting is correct. The 
procedures involved here must only be carried out by trained personnel.  
 
 
 
 
Note 
To ensure a high control loop dynamic response (high k
V
 factor), rapid, overshoot-free 
positioning, and smooth running, measuring systems that emit a minimum of approx. 10,000 
pulses/revolution are recommended. 
 
 
 
 
Note 
To protect against contamination, the housing for the encoder on the axes construction of 
the built-in torque motor must fulfill degree of protection IP54 to EN 60529. 
The permissible mechanical speed and limit frequency of the encoder and Control Unit must 
be taken into account. Refer to the appropriate documentation issued by the manufacturer 
when configuring, installing, and adjusting the encoder  
 
 
 
 
Note 
The encoder pulse numbers must be able to be divided by 10 or 16 in order to be able to use 
the zero mark monitoring function of the drive system.
