RISK ASSESSMENT
Under fault conditions, power loss or unintended operating conditions, the drive may not operate as intended. In particular:
•
Stored energy might not discharge to safe levels as
quickly as suggested, and can still be present even
though the drive appears to be switched off
•
The motor's direction of rotation might not be controlled
•
The motor speed might not be controlled
•
The motor might be energised
A drive is a component within a drive system that may influence its operation or effects under a fault condition.
Consideration must be given to:
•
Stored energy
•
Supply disconnects
•
Sequencing logic
•
Unintended operation
