The IC´s marked in your picture D31 and D32 are PAL´s (hard programmed), responsible for conditioning of thyristor firing pulses for torque direction 1 and 2. You run the device with Firmware V3.3 (EPROM´s D3 and D4). As 6RA22 is a discontinoued product it can be difficult to get spare parts. Try an official support request ( http://support.automation.siemens.com/WW/view/en/16604318) and ask for spare parts from the repair center in Fuerth, departement I IA CE SE MF RS PP Or you change the complete converter to an actual device. Here you find the selection guide: http://support.automation.siemens.com/WW/view/en/26117308 regards frimos |
