The output voltage at terminal 13 is 5V when Pr 3.23 is set at 0 (default).
When Pr 3.23 is set at 1, the output voltage will become 15V. This could
damage encoders that require a 5V supply.
Termination resistors should be disabled by setting Pr 3.24 to 1 if the
encoder output is 15V.
This terminal is connected internally to terminal 8 of the signal connector
Connect only one of these terminals to a motor thermistor. Analog input
3 must be in thermistor mode, Pr 7.15 = th.Sc (9) or th (10).
