If Pr 34 is set to th so that terminal B7 is used as a motor thermistor, the functionality of
terminal B7 as set-up with Pr 05, drive configuration, will be disabled.
When setting to th, press mode four times. Analog reference 2 will no longer be selected
as the speed reference. Analog reference 1 should be used.

This parameter is automatically changed by the setting of Pr 12. When Pr 12
automatically controls the setting of this parameter, this parameter cannot be changed.
NOTE
A change to this parameter is only implemented if the drive is disabled, stopped or
tripped and the STOP/RESET key is pressed for 1s.
