2.13 Commissioning SIMOTICS 1FW6 built-in torque motors
PTC connection via thermistor motor protection device 3RN1013-1GW10
You can evaluate the PTC sensors via a thermistor motor protection device 3RN1013-
1GW10. The normally closed contact must be connected to the temperature input at the
Motor Module (terminals X21.1 X21.2).
For a parallel connection of several motors, a thermistor motor protection device 3RN1013-
1GW10 must be used for each motor. The NC contacts must be connected in series.
Table 2- 20 Parameterization in the drive:
Parameter Input
p0600 Motor temperature sensor for monitoring
11: Temperature sensor via Motor Module / Control Unit terminals
p0601 Motor temperature sensor, sensor type
4: Bimetallic NC contact alarm & timer (only for temperature evaluation via the Motor Module)
p0604 Motor temperature alarm threshold
Sets the alarm threshold for monitoring the motor temperature.
Pre-assignment,120 °C
p0605 Motor temperature fault threshold
Sets the fault threshold for monitoring the motor temperature.
Pre-assignment,155 °C
p0606 Motor overtemperature timer
Maximum 0.1 s; for the bimetallic switch, you must select a timer of 0.1 s to ensure that the motor is
reliably shutdown.
If the timer has expired, then fault F07011 is output.
Testing temperature sensors for interconnection via the thermistor motor protection device
To test the PTC connection, remove at least one contact. F07011 is displayed after the time
set in p0606 has expired (in this case, 0.1 s).
