Note: With this selection, the control program converts the
analog signal to PTC resistance value in ohms and shows it
in parameter 35.02 The parameter name and unit still refer to
temperature.
PTC sensor connected to the analog input selected by

divider connection must be in use instead of the normal PTC
connection. The voltage divider connection uses the
terminals +10 V, digital input and analog input. See the drive
hardware manual for the actual connection.
This selection makes it possible to connect the PTC when no
analog output is available.
The required settings are same as with selection
analog I/O.
Notes:
• This is applicable only for frames R0...R2.
• Make sure that the digital input that you connect to this
voltage divider circuit is not used for any other purpose in
the control program.
• With this selection, the parameter

Note: If the measured temperature source selection (35.11) is
PTC analog I/O or PTC AI/DI Voltage divider tree, the motor
thermal protection function converts the analog input signal
(35.14) to PTC resistance value (ohms). Also this limit is then
a resistance value even the parameter name and unit refer to
motor temperature (°C or °F). You cannot change the unit to
ohm by the time being (96.16).
