The drive contains the following printed circuit boards as standard:
• main circuit board (AINT)
• motor control and I/O board (RMIO) with a fibre optic link to the AINT board
• input bridge control board (AINP)
• input bridge protection board (AIBP) which includes snubbers for the thyristors
and varistors
• power supply board (APOW)
• gate driver control board (AGDR)
• diagnostics and panel interface board (ADPI)
• brake chopper control board (ABRC) with D150
