There will be two variants of the service:
Drive Health Check, for ABBs ACS607 and ACS800-07 drives, will offer detailed measurements and inspection which will take place during planned shutdowns. The current condition of the drive will be assessed, and recommendations given for short-term and long-term maintenance.
Drive Stress Check, for its ACS800 and ACS880 single drives and multi-drive modules, will need no shutdown, and can be performed during normal operation. It will identify the stress status of the drive resulting from harsh environments or heavy-duty applications, and recommend ways of mitigating their effects.
It is estimated that VSDs can achieve a mean time between failure (MTBF) of more than half a million hours equivalent to 62 years but this is possible only if they are maintained correctly and regularly.
