If you are not using a standard motor, then you must parameterize parameters
p0600...p0606 (see above). Select parameters p4600...p4603 to match the sensor types or
temperature channels of the Sensor Module External SME12x.
Checking the temperature sensors for the Sensor Module External SME12x
In the online mode, you can read out the temperatures of the sensors at the channels of the
Sensor Module External SME12x using parameter r4620[0...3] using the STARTER
commissioning tool.
The maximum motor temperature can also be read in r0035. This parameter indicates the
highest value from parameters r4620[0...3].
For a parameterized PTC sensor type, irrespective of the actual temperature in r4620 - 200
°C is always displayed.
If a negative value in the range from – 40 °C to – 80 °C is displayed in parameter r0035 or
r4620[1], then the KTY connection has been interchanged with that of the PTC.
Checking the PTC sensor type
You can simulate a sensor responding to an overtemperature condition (high ohmic state) by
disconnecting the connections. You can disconnect the connections for the temperature
sensors by removing the Sensor Module External SME12x (connector, interface X200).
If the sensor type is parameterized as PTC fault, then fault "F07011 drive: Motor
overtemperature" is immediately displayed independent of the setting of p0604 - p0606. If
the sensor type is parameterized as PTC alarm with timer, after the time parameterized in
p0606, fault F7011 is generated.
Checking the KTY sensor type
When you withdraw the connector of interface X200, and have therefore disconnected the
KTY connection, after the time parameterized in p0607 has expired, fault "F07016 drive:
Motor temperature sensor fault" is displayed in the alarm window of the STARTER
commissioning tool.
Check the wiring of the temperature sensors, by checking the resistance values at connector
interface X200. The wiring is OK for the following resistance values:
KTY 84 at 20 °C, approx. 570 Ω
PTC at 20 °C, 120 Ω – 240 Ω
