The STO option is not compatible with these PowerFlex 7000 configurations:
• 18 Pulse SCR rectifiers
• SGCT redundant devices (for example, N+1, N-1 configurations)
• Parallel drives
• Use of bypass contactor (for example, synchronous transfer, separately
controlled bypass contactor)
• Mechanically-held drive input contactors (for example, option 3950_)
• Versions of the drive firmware prior to 10.002
• Versions of the drive hardware prior to ForGe control
The STO option does not allow for:
• Automatic restart if medium voltage is interrupted for long enough to
discharge the gate driver power supplies on an SPS rectifier.
• More than a 200 ms ride through capability of the input starter control
with an IntelliVAC™ Contactor Control Module (see 1503-UM053).
All PowerFlex drive parameters related to the STO option are in the functional
safety group. Functional Safety Mode is the only writable parameter, and must
match the hardware installed (for other drive configuration parameters, see
Table 5). If this parameter is enabled, there must be OIBBS and OIB2s
installed to run the drive. The access mode must be at least advanced to change
this parameter (see publication 7000-UM201).
