Commissioning Manual, (IH1), 01/2012, 6SL3097-4AF00-0BP2
– Power unit (connect UVW, phase sequence, clockwise rotating field)
– Protective conductor connected?
– Shield connected?
– Temperature monitoring circuits:
Are the cables connected to the terminal block of the shield connecting plate?
Temperature sensor (Temp-F):
With the temperature sensor (Temp-F), the average absolute winding temperature can
be measured.
Overtemperature switch (Temp-S):
The overtemperature trip circuit (Temp-S) enables each individual motor phase
winding to be digitally monitored for an overtemperature condition.
DANGER
The circuits of Temp-F and Temp-S neither have "protective separation" between
each other nor to the power circuits in accordance with IEC 61800-5-1.
The temperature monitoring circuits must be connected via the Sensor Module
SME12x so that the specifications of the EN 61800-5-1 are fulfilled. These
specifications are not fulfilled when the temperature monitoring circuits are
connected via the SMC20 Sensor Module.
Also refer to the Configuration Manuals for 1FN1, 1FN3 or 1FN6 linear motors.
– Temperature sensor evaluation
– Temperature monitoring with SME12x, (description of the temperature monitoring
circuits see - connection to the SME12x in the Configuration Manual 1FN1, 1FN3 or
1FN6 in chapter "Thermal motor protection", description for connection to the
SME12x, see chapter "Connection of the temperature monitoring circuits)
– Encoder system connection
Is the encoder system connected correctly to SINAMICS?
