EP terminals
Parameters are used to set the filter times to debounce terminals X21.3 and X21.4, as well
as X22.3 and X22.4 (see the SINAMICS S120/S150 List Manual). Additional parameter
settings are also required in order to prevent discrepancy errors when performing bit pattern
tests (light/dark tests). For comprehensive information, see the SINAMICS S120 Safety
Integrated Function Manual, Section "Controlling the safety functions".
Note
Function of the EP terminals
The function of the EP terminals is only available when Safety Integrated Basic Functions
are enabled.
Temperature sensor connection
NOTICE
Risk of the motor overheating due to an incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats.
• Always connect the KTY sensor with the correct polarity.
Note
The temperature sensor input is not needed if the motors feature an integrated DRIVE-CLiQ
interface or if temperature values are detected by means of a different module (SMC, SME,
TM).
