Commissioning
2.13 Commissioning linear motors (servo)
Note
Without using a suitable protective module (e.g. TM120), for safe electrical separation it is
not permissible to connect Temp-F to a Sensor Module of the SINAMICS drive system.
The drive must always be switched into a no-voltage condition. When handling and
connecting Temp-F, when the drive is switched-on, hazardous voltages can be present at
the terminals on the motor side and at the Temp-F connecting cable.
Note
If a 3RN1013-1BW10 thermistor motor protection device or a suitable protective module is
not used, then for safe electrical separation it is not permissible to connect Temp-S to a PLC
or to a Sensor Module of the SINAMICS drive system.
The drive must always be switched into a no-voltage condition. When handling and
connecting Temp-S, when the drive is switched-on, hazardous voltages can be present at
the terminals on the motor side and at the Temp-S connecting cable.
Temperature evaluation unit with safe electrical separation
Terminal Module 120 is a temperature evaluation unit with DRIVE-CLiQ interface for
installation in a control cabinet. The TM120 has 4 measuring channels with safe electrical
separation to connect KTY or PTC temperature sensors. A TM120 can also be used with
Sensor Modules for encoder evaluation (SMCxx, SMIxx and SMExx) if safe electrical
separation of the temperature sensors is necessary.
