Siemens SIMOTICS T-1FW6 User Manual

Check OK
Are the motor power cables correctly connected to the power module with the UVW
phase sequence (clockwise rotating 󹪝eld)?

Do the temperature monitoring circuits ful󹪝ll the speci󹪝cations of protective separation?
Important additional information on the temperature monitoring circuits Temp-S and
Temp-F are provided in the Con󹪝guration Manual "SIMOTICS T-1FW6 built-in torque mo‐
tors".

Before commissioning and switching on the DC link voltage for the 󹪝rst time, have you
checked the temperature monitoring circuits to ensure that they correctly trip?

Has the encoder been correctly connected? 
Have the digital and analog signals been routed using separate cables? 
When designing and installing, have you carefully complied with the EMC installation
directives of the inverter manufacturer?

Have the line-side and motor-side power cables been dimensioned and routed in accord‐
ance with the environmental and routing conditions?

Have the maximum permissible cable lengths between the frequency converter and the
motor (depending on the type of cables used) been observed?

7.3 Checking the insulation resistance
Notes for checking the insulation resistance
Installation inspection, preventive maintenance and troubleshooting are examples of required
checking of the insulation resistance on a machine/system with direct drives or directly on the
motors.
WARNING
Risk of electric shock
If you check the insulation resistance using high voltage, this can damage the motor insulation.
There is a risk of death or serious injury if energized parts are touched.
• Only use test equipment that is in compliance with DIN EN 61557-1, DIN EN 61557-2 and
DINEN61010-1 or the corresponding IEC standards.
• Check the insulation resistance on the individual motors only according to the following
procedure.
• If a DC voltage > 1000V or an AC voltage is necessary to test the machine/system, then
coordinate this test with your local sales partner.
• Carefully observe the operating instructions of the test device.
