X21 EP terminal/temperature sensor
Table 6- 49 X21 EP terminal / temperature sensor
Temperature sensors: KTY84–1C130 / PT1000 / PTC /
bimetallic switch with NC contact
Supply voltage: 24 V DC (20.4 ... 28.8 V)
Current consumption, typical: 4 mA at 24 V
Isolated input
The pulse inhibit function is only available when the
"Safety Integrated Basic Functions via onboard termi-
nals" software is enabled.
4 EP M1 (enable pulses)
Type: Screw terminal 1 (Page 730)
The filter times to debounce terminals X21.3 and X21.4 can be parameterized (see
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 for pulse inhibit is only available if the "Safety Integrated
Basic Functions via onboard terminals" software is enabled.
Temperature sensor connection
Damage to motor in the event of incorrectly connected KTY temperature sensor
A KTY temperature sensor connected with incorrect polarity cannot detect if the motor
overheats. Overheating can cause damage to the motor.
• Connect the KTY temperature 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).
