Configure and Start Up the Drive
Turn Safety On (SSM and S4 Only)
1. In the Controller Organizer, under the heading Safety Task, double-
click on Main Routine.
2. When the Safety Ladder logic opens, select the status words to change
the status from Off to On.
When this is complete, the safety enable in the drive is on and active and is
ready to continue with setup.
For additional information on configuring the SSM or S4 option module, refer
to PowerFlex 755/755T Integrated Safety Functions Option Module (S4),

Energize the Incoming Power and Brake Circuit Breakers
After you have completed the configuration of the drive, energize the main
incoming 400/480V AC and the brake circuit breakers. See
for more information.
1. Use the cover-mounted HIM, Connected Components Workbench
Software, Drive Executive, or Logix Designer application to monitor
00:11 [DC Bus Volt])
.
– With the main input energized, the voltage should be 515V DC
(with 400V AC input)…650V DC (with 480V AC input).
– If circuit breakers 1 and 2 are both energized properly,
07:01 [Dig In
Sts] bit 1 = 1
. If
07:01
bit 1 equals 0, the circuit breakers are tripped.
If the voltage is outside of this range, go upstream to the power
distribution system and verify that the 3-phase power is being provided
to the drive.
2. With incoming, brake, and control power energized and verified, open
the controller safety program in the Logix Designer application, and
enable the Safe Torque Off bit of the PowerFlex drive.
In our example, PowerFlex 755_PTP_Turntable:SO. SafeTorqueOff is
shown energized which enables the safety circuits in the PowerFlex 755.
3. With safety energized, the HIM display should change from Not
Enabled to Stopped.
ATTENTION:
Equipment damage could occur if you try to operate without
proper power. Do not proceed to the next step until proper 3-phase power
and brake power are provided to the PowerFlex 755 On-Machine Drive.
IMPORTANT
Safety must be energized and all faults in the drive cleared before any
additional commissioning can be done.
