Safety Stop Function
Safety stop function prevents the motor starting accidentally.
DANGER!
Even when the safety stop function is active, dangerous voltage levels may be
present in the motor. Thus, before any intervention on electrical parts, the system
must be completely de-energized.
DANGER!
Even after switching off or disconnecting the power supply, the inverter may
remain charged with high voltages and/or have moving parts (fans). Wait for at
least 10 minutes in order to guarantee the full discharge of internal components.
ATTENTION!
In case of multiple faults in the power stage of the inverter, the motor shaft can
rotate up to 360/(number of poles) degrees, even with the activation of safety stop
function. That must be considered in the application.
NOTE!
Inverter safety stop function is only one component of the safety control system of a
machine and/or process. When inverter and its safety stop function is correctly used
and with other safety components, it is possible to fulfill the requirements of the
relevant standards: EN ISO 13849-1 (Cat. 3 / PL d) and EN 61800-5-2 / IEC 62061 /
IEC 61508 (SIL 2).
