Ptc Inputs For Motor Ptc Thermistor - Siemens SINAMICS G180 Installation And Operating Instructions Manual

16. Depending on parameter "P-INVERTER DATA/P-Monitoring/STO." You must
17. The inverter tests the shutdown paths according to step 9. and 10.
Resolving problems
For an incorrect setting at the bail switch S3 on peripheral board DI/DO and/or parameter
"P-INVERTER DATA/ STO" result in the following different responses. Recheck the settings.

For all additional deviations when checking the "Safe torque off" function, it is crucial that you
contact a service station or the factory.
Note
The inverter tests the two shutdown paths:
• After the "Safe torque off" function is tripped.
• After acknowledging the fault "!! Inverter fault !!" "Test safe torque off".
• After acknowledging the ATEX motor temperature monitoring "!! Fault !!" "PTC thermistor
X3:90/91".
• Each time the control voltage is switched on (supply for the various boards).
• If the test is initiated using parameter "P-EXTRAS/Test STO/PTC".

PTC inputs for motor PTC thermistor

The peripheral boards 2 / 4 provide two PTC thermistor inputs at the control cable terminals
-X3:90-93 for the motor temperature monitoring. When using the inputs, remove the 100 Ω
resistor connected there.
Peripheral board 1 and peripheral board 3 have control cable terminals for the PTC inputs.
However, there is no evaluation board. No monitoring is made if you connect PTC
thermistors.

acknowledge again. See Step 9.
Different response
The inverter either displays no response -
or just that response that is parameter-
ized for input X2:24, independent of the
"Safe torque off" function.
The inverter changes into state "Fault"
with display "!! Fault !!" "S7 inactive"
The inverter changes into state "Fault"
with display "!! Inverter fault!!" "Test safe
torque off".
The inverter changes into the "Switch
interlock" state, LED "READY" goes dark.
The "Safety torque off" "active" message
is displayed at the converter.

Incorrect setting
You have neither set switch S3 nor the
parameter to the two-circuit trip.
You have set switch S3 to the two-circuit
trip and the
parameter to single-circuit trip ("X2:20").
You have set switch S3 to the single-
circuit trip and the
parameter to two-circuit trip ("X2:20/24").
You have either only set the parameter or
simultaneously also switch S3 to the
single-circuit trip.
