Assignment Of The Analog Outputs; Input "Safe Torque Off" / Ptc Thermistor Inputs On Peripheral Board - Siemens SINAMICS G180 Installation And Operating Instructions Manual

8.8.1.10

Assignment of the analog outputs

● Isolated terminal -X2:62, 63:
An output signal of 4 mA to 20 mA is present here. This corresponds to a motor current
from zero up to a unit-dependent value.
● Isolated terminal -X2:60, 61:
This output provides a speed signal. A value from 4 mA to 20 mA is the default. This
corresponds to a motor speed from 0 to 1500 rpm.
● Terminal -X2:64, 67:
In the case of the "peripheral board 1 ... 4" option, the torque and the power are available
at these terminals. A value from 4 mA to 20 mA is the default. The corresponding
countervalue is output-dependent and is stored in the software "IMS".

Input "Safe torque off" / PTC thermistor inputs on peripheral board

● Terminal -X2:19/:20:
These terminals are dedicated for triggering the "Safe torque off" function.
This input is jumpered in the default setting. If you wish to use the "Safe torque off"
function, then you must remove this jumper and connect an NC contact of the switching
element that triggers the function.
● Terminal -X2:24
This terminal can be configured as a second trigger circuit for the "Safe torque off"
function. The DIP-FIX switch (bail switch) -S3 on the peripheral board determines
whether the "Safe torque off" function is controlled through one or two circuits.
-S3 closed means through two circuits.
To use this input as second circuit for the "Safe torque off" function, you must connect
terminal -X2:24 with -X2:3 using an NC contact of the appropriate switching element.
● Terminal -X3:90/:91:
This input is used for motor temperature monitoring certified according to ATEX. If you
wish to use this monitoring function, then you must remove the existing resistor and
connect the appropriate motor PTC thermistor.
Installation and Operating Instructions SINAMICS G180
Operating Instructions, 02/2019, 4BS0751-007
NOTICE
Peripheral board 2 or 4 is required for monitoring
The monitoring function is only available if the required peripheral board 2 or peripheral
board 4 is inserted in the SINAMICS G180
If the peripheral board 1 or peripheral board 3 is installed, then although the terminals
are available, there is no evaluation. There is no monitoring.
