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
