Ambient conditions
For the environmental limits for the safety functions and the drive,
refer to the hardware manual of your drive.
Safety data
The FPTC-02 module is a type A safety component as defined in
IEC 61508-2. For the types of the drive/inverter STO and the FSO
module, see the applicable hardware manual or FSO user's manual.
The table gives the safety data for the SMT function with different
configurations. The calculations are based on the worst case data of
the drive Safe torque off (STO) function. The PFH/PFD
avg
values can
be different based on the internal configuration of the FSO module.
