Thyristor Failure and Fuse Blowing Problem are occurs in 4 quardent DC Drives.

Due to following reasons Thyristor Failure and Fuse Blowing Problem occurs.

1- Due to  faulty Power Card , to confirm this please run thyristor check in DC Drives with On command. For 6RA70 Simoreg DC Master drive Parameter no P830 and for 6RA80 Sinamics DCM Drive Parameter no P50830 are available for thyristor check if found Power Interface card faulty Please Get This Card Repair From us are from anywhere.

2- Power Supply failure during operation is one of Major reason for Thyristor Failure and Fuse Blowing .“We have solution for this problem please contact us “

3- Incorrect optimization of Speed controller and Current controller we can help you please contact us.
