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).

Note
Cable shield for the encoder connection via terminals
Note that when the encoder is connected via terminals, the cable shield must be applied to
the module.
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.
