NOTICE
Setting the encoder power supply
The encoder power supply can be parameterized to 5 V or 24 V. The encoder may be
destroyed if you enter the wrong parameter.
KTY temperature sensor connected with the correct polarity
The KTY temperature sensor must be connected with the correct polarity.
If the polarity is reversed, the sensor will not be able to detect if the motor overheats.
Risk of electric shock!
Only temperature sensors that meet the safety isolation specifications stipulated in
EN 61800-5-1 may be connected to terminals "+Temp" and "-Temp".
Failure to observe these instructions can result in electric shock!
