Siemens SINAMICS GM150 Deep Maintenance

On-site maintenance

Check and clean pre-charge loop, rectifier unit, diode characteristics, inverter unit, GSV, AVT.

Rectifier module diagnostic test, and high voltage switchgear interface function test.

The IGBT POWERCARD of the GM150 is statically tested and cleaned to check the IGBT pairing condition.

Control cabinet inspection, BENDER insulation test, PT100, SITOP, etc.

CU320, TM31/15, AOP30, I/O terminal check.

Fiber optic connection and transmission characteristics, input/output cable connection and shielding conditions.

Tighten the ground copper bar, check the bolt fastening connection (torque), and insulation of the device.

On the control power, on the main power test, load running.

Record and analyze the output voltage, output current, speed (given value, actual value), DC bus waveform and other curves.

check

Check the operation of frequency converter on site.

Download and save frequency converter history, backup parameters, procedures.

Check the electrical installation and power cable layout.

Collect and monitor the output data.

Deep cleaning instructions

Use a brush and vacuum cleaner or dry compressed air to thoroughly clean the dust inside the cabinet. The scope of cleaning is the main internal components, other cleaning such as cabinet shell, cabinet body, external environment by Siemens technical staff to guide customers to complete.
