ATTENTION!
In case of a multiple fault 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's possible to fulfill the requirements of standard EN 954-1 / ISO 13849-1, Category 3 (machine
safety) and IEC/EN 61508, SIL2 (safety control/signaling applied to processes and systems).
The parameter P0029 shows if the inverter has identified correctly SRBXX board. See Bit 9 in
for details.

NOTE!
If the degree of protection of the used inverter is lower than IP54, it must be installed inside an IP54
(minimum) cabinet.

NOTE!
Terminals XC25: 2 and XC25: 4 are not internally connected to the reference of the inverter power
supply +24 V. These terminals are often connected to the control terminal XC1:11.
