Forming of DC Link Capacitors for 60 Siemens Siemens SINAMICS VFD different sizes
Project Scope:
Because the motor modules were stored for more than two years, the DC link capacitors required reforming to prevent damage when powering up the units. The installed Siemens SINAMICS VFD drives had been out of operation since 2017, and before restarting them, it was essential to perform capacitor forming.
Total Installed VFD Drives: 60 units with different ratings.
