Table 2- 16 Checklist (3) - checking the electrical system
Check
Has all wiring work been successfully completed?
Is the protective conductor correctly connected?
Is the motor ground directly connected to the Power Module ground (short distance in order to avoid high
leakage currents)?
Are all connectors correctly plugged in and screwed in place?
Are the motors connected with shielded power cables?
Are the power cable shields connected as closely as possible to the terminal box across a wide area?
Are all cable shields connected to the respective housing through a large surface area?
Have the control cables been connected in accordance with the required interface configuration and the
shield applied?
Have the motor power cables been correctly connected to the power module with the phase sequence
UVW (clockwise rotating field)?
Do the temperature monitoring circuits fulfill the specifications of protective separation?
Additional important information on temperature monitoring circuits Temp-S and Temp-F can be found in
the Configuration Manual "SIMOTICS T-1FW6 built-in torque motors".
Before commissioning and before switching on the DC link voltage for the first time, have you checked
the temperature monitoring circuits to ensure that they correctly trip/shut down?
Is the encoder correctly connected?
Are the digital and analog signals routed using separate cables?
Has the distance from power cables been observed?
Have the line-side and motor-side power cables been dimensioned and routed in accordance 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?
