Mechanical brake control
The brake control functions are provided to allow well co-ordinated operation of an
external brake with the drive. While both hardware and software are designed to high
standards of quality and robustness, they are not intended for use as safety functions,
i.e. where a fault or failure would result in a risk of injury. In any application where the
incorrect operation of the brake release mechanism could result in injury, independent
protection devices of proven integrity must also be incorporated.
Adjusting parameters
Some parameters have a profound effect on the operation of the drive. They must not
be altered without careful consideration of the impact on the controlled system.
Measures must be taken to prevent unwanted changes due to error or tampering.
Electrical installation
Electric shock risk
The voltages present in the following locations can cause severe electric shock and may
be lethal:
• AC supply cables and connections
• Output cables and connections
• Many internal parts of the drive, and external option units
Unless otherwise indicated, control terminals are single insulated and must not be
touched.
Stored charge
The drive contains capacitors that remain charged to a potentially lethal voltage after the
AC supply has been disconnected. If the drive has been energized, the AC supply must
be isolated at least ten minutes before work may continue.
