Verify Operation - Allen-Bradley PowerFlex 7000 Series User Manual

Verify Operation

Test the safety function for proper operation after initial installation of the
drive or STO retrofit kit. Retest the safety function at the intervals determined
by the safety analysis described on
drive commissioning procedure is complete.
IMPORTANT The input component of the STO system in the drive is an Allen-Bradley
Minotaur MSR127 Safety Relay. Perform an STO functional test at least once
every six months to maintain the safety rating.
Verify the interlocking of the drive input isolation device and the ability of the
STO system to open this device.
Table 6 - Power Up
Complete? Description
Upon power up of the drive, ensure there is no fault code 657 or code 689 (i.e., Rec InpCtrctrClsd or
Inv InpCtctrClsd).
Reset any faults in the drive, and put the system in the normal running state (i.e., reset the STO
active state).
Run the drive above 5 Hz and ensure Rec General Flt (code 639) and Inv General Flt (code 671) are not
generated because the input device feedback for the STO system is not the correct status.
Stop the drive and set the input contactor to critical faults. This parameter is in the feature select
group, P1 Input Ctctr Cfg.
a. Reset any faults that exist and reset the STO feature.
The input device should be on and supplying MV to the drive. Ensure the drive is NOT running.
b. Remove any one of the fiber optic cables on the inverter OIB2s.
c. Verify that relays KG_STO and KG_DIC open, and that the drive input device opens.
The only fault generated should be an Inverter PSD fault 690.
d. Reinstall the fiber optic cable, ensuring it is seated properly.
e. Reset any faults that exist and reset the STO feature.
The input device should be on and supplying MV to the drive. Ensure the drive is NOT running.
f. Using a screwdriver, force the white indicator in on relay KG_DIC so it does not open for
steps g. and h.
g. Remove any one of the fiber optic cables on the inverter OIB2s.
h. Verify that relay KG_STO opens and the drive input device opens.
The only fault generated should be an Inverter PSD fault 690.
Reinstall the fiber optic cable, ensuring it is seated properly. Reset the faults and STO feature. Ensure
any changed parameters are set back to the correct state.
