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".

Function of the EP terminals

The function of the EP terminals is only available when Safety Integrated Basic Functions

are enabled.

Temperature sensor connection

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

• Always connect the KTY sensor with the correct polarity.

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,

Danger to life due to electric shock in the event of voltage flashovers at the temperature

Voltage flashovers in the signal electronics can occur in motors without safe electrical

separation of the temperature sensors.

• Use temperature sensors that fully comply with the specifications of the safety isolation.

• If safe electrical separation cannot be guaranteed (for linear motors or third-party

motors, for example), use a Sensor Module External (SME120 or SME125) or Terminal

Module TM120.
