Checklist (3) – Checks regarding the electrical system
Check
OK
Has all wiring work been successfully completed?
Is the protective conductor correctly connected?
Is the ground for the motors directly connected to the ground for the power modules
(short distance to avoid high discharge 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
through the widest possible surface area?
Are all cable shields connected to the respective housings through the largest possible
surface area?
Have the control cables been connected in accordance with the required interface
configuration and the shield applied?
Are the motor power cables correctly connected to the power module with the UVW
phase sequence (clockwise rotating field)?
Do the temperature monitoring circuits fulfill the specifications of protective
separation?
Important additional information on the temperature monitoring circuits Temp-S and
Temp-F are provided in the Configuration Manual "Naturally cooled SIMOTICS T-
1FW6 built-in torque motors".
Before commissioning and switching on the DC link voltage for the first 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
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?
