Parameters 283
PTC analog I/O PTC sensor connected to analog input selected by parameter
35.14 Temperature 1 AI source and an analog output.
The required settings are the same as with selection KTY84
analog I/O.
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 AI/DI Voltage
Divider tree
PTC sensor connected to the analog input selected by
parameter 35.14 Temperature 1 AI source. A special voltage
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 KTY84
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 35.02 shows PTC
resistance in ohms, not motor temperature even the
parameter name and unit still refer to temperature.

35.12 Temperature 1 fault
limit
Defines the fault limit for temperature supervision function 1.
When measured temperature 1 exceeds the limit, the drive
trips on fault 4981 External temperature 1.
The unit is selected by parameter 96.16 Unit selection.
130 °C or
266°F or
4500 ohm
-60…5000 °C or
-76…9032 °F or
0...5000 ohm
Fault limit for temperature monitoring function 1.
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).

35.13 Temperature 1
warning limit
Defines the warning limit for temperature supervision
function 1. When measured temperature 1 exceeds the limit,
warning A491 External temperature 1 is generated.
The unit is selected by parameter 96.16 Unit selection.
110°C or
230°F or
4000 ohm
-60…5000 °C or
-76…9032 °F or
0...5000 ohm
Warning limit for temperature monitoring function 1.
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).
