Max. connectable cross-section: 1.5 mm
When using unipolar HTL encoders, at the terminal block A*, B*, R* must be connected to (jumper) M_Encoder (X531)
Because the physical transmission properties are more robust, the bipolar connection
1)
should always be used. The unipolar connection should only be used if the encoder type
does not output push-pull signals.
CAUTION
When the encoder system is connected via terminals, make sure that the cable shield is
connected to the component. Refer to the section titled "Electrical connection".
NOTICE
The KTY temperature sensor must be connected with the correct polarity.
Hazard due to electric shock
Only temperature sensors that meet the protective separation specifications in EN 61800-5-
1 may be connected to terminals "+Temp" and "-Temp". There is a risk of electric shock if
this is not carefully observed.
