Outline
The safety function is incorporated in the SERVOPACK and the converter to reduce
the risk associated with the machine by protecting workers from injury and by secur-
ing safe machine operation. Especially when working in hazardous areas inside the
safeguard, as for machine maintenance, it can be used to avoid adverse machine
movement.
The person who designs a system using the safety function (Hard Wire Baseblock
function) must have full knowledge of the related safety standards and full under-
standing of the user’s manual for your SERVOPACK.
