NOTICE
Damage to motor when KTY temperature sensor is connected incorrectly
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 supply voltage can be assigned as 5 V or 24 V. Incorrect parameter
assignment can cause damage to the encoder.
• Select the appropriate supply voltage.
