Start Up
This chapter describes how to start up the PowerFlex® 527 drive.
Prepare for Drive Start-Up
Before starting up the drive, it is recommended to perform the startup tasks
described below to ensure a smooth startup and drive operation. Ensure that the
drive is not powered (check that DC Bus voltage is less than 50V DC) before
proceeding with the startup task list.
Drive Startup Task List
1.
Disconnect and lock out power to the machine.
2.
Verify that AC line power at the disconnect device is within the rated value
of the drive.
3.
If replacing a drive, verify the current drive’s catalog number. Verify all
options installed on the drive.
4.
Verify that any digital control power is 24 volts.
5.
Inspect grounding, wiring, connections, and environmental compatibility.
6.
Verify that the Sink (SNK)/Source (SRC) jumper is set to match your
control wiring scheme. See the
PowerFlex 527 Control I/O Wiring Block
for location.
