NOTICE
Damage to the motor in the event of incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating can cause damage to the motor.
• Connect a KTY temperature sensor with the correct polarity.
NOTICE
Damage to the encoder due to incorrect supply voltage
The encoder power supply can be parameterized to 5 V or 24 V. The encoder may be
damaged if you enter the wrong parameter.
• Select the appropriate supply voltage.
