Note
Operation of unipolar HTL encoders
When unipolar HTL encoders are used, terminal block A*, B*, and R* must be jumpered with
M encoder (-X531).

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.
