Sensor Module External SME12x is a module to evaluate:
● Incremental encoders with sin/cos 1 V
PP
interface (SME120)
● Absolute encoders with EnDat interface (SME125)
● Temperature sensors
The temperature sensors in the motor do not have safe electrical separation in order to
achieve better thermal contact to the motor winding.
The SME12x evaluates the temperature sensors with safe electrical separation.
Information about the SME12x is provided in the "SINAMICS S120 Control Units and
Additional System Components" Equipment Manual.
The TM120 Terminal Module is a module for evaluating temperature signals.
The temperature sensors in the motor do not have safe electrical separation in order to
achieve better thermal contact to the motor winding.
Terminal Module TM120 evaluates the temperature sensors with safe electrical separation.
Information about the TM120 is provided in the Equipment Manual "SINAMICS S120 Control
Units and Additional System Components".
The Sensor Module Cabinet-Mounted SMC20 is a module to evaluate:
● Incremental encoders with sin/cos 1 V
PP
interface
● Absolute encoders with EnDat interface
Information about the SMC20 is provided in the "SINAMICS S120 Control Units and
Additional System Components" Equipment Manual.
Pin assignments and connection types
The 1FN3050 motors either have a permanently connected combined cable or two separate
permanently connected cables for the power connection and the signal connection. There is
a choice of 0.5 m length and preassembled connectors (size 1 or M17) or 2 m length and
open conductor ends for these cables.
The 1FN3100 to 1FN3900 motors are provided with separate cables for the power
connection and signal connection. To connect these motors, use the connection cover with
metric cable glands directly on the integrated terminal panel.
