PowerFlex 753 Drive (P_PF753)
•
If your PowerFlex 753 drive uses the 20-750-ENETR EtherNet interface,
use the P_PF755 instruction instead. The PowerFlex 753 drive with the
20-750-ENETR interface uses the same interface data structures as the
PowerFlex 755 drive, giving you more data.
•
If you are using a drive other than the PowerFlex 523, 525, 753, or 755,
drive, use the P_VSD (generic variable-speed drive) instruction instead.
Functional Description
The P_PF753 instruction provides the following capabilities:
•
Ownership of the drive through the standard P_Mode Add-On
Instruction and modes.
•
Ability to start and stop the drive and motor, control the drive speed (via
speed reference), and monitor the drive run status and speed feedback to
verify the drive is running or stopped. Provides alarms and drive shutdown
for Fail to Start and Fail to Stop if the feedback does not follow the
commanded state within a configured amount of time.
•
Reading from the drive, the instruction displays drive faults, drive alarms,
conditions that inhibit starting the drive, drive predictive maintenance
data, and general drive status data.
•
Ability to read a fault code from the drive and provide descriptive text of
fault codes.
•
Indication of Accelerating, Decelerating, At Speed, Warning, or Alarm
status as received from the drive.
•
Optional capability to support reversing drives, with commands for
forward and reverse rotation, and display of actual rotation direction.
•
Input and alarm for a drive fault condition and an output to send a drive
fault reset to the drive. Provides a configurable time to pulse the drive fault
reset output when a reset command is received.
•
Permissives (bypassable and non-bypassable), which are conditions that let
a drive start, and Interlocks (bypassable and non-bypassable), which are
conditions that stop the drive as well as prevent starting. Provides an alarm
when an Interlock stops the drive. Provides maintenance personnel the
capability to bypass the bypassable Permissives and Interlocks.
•
Maintenance personnel have the capability to disable (soft lock out) the
drive. This capability is not a substitute for hard lockout/tagout (LOTO)
procedures.
•
Monitor an I/O fault input, and alarm on an I/O fault. The I/O fault
condition can optionally de-energize the outputs to the drive, requiring
a reset.
•
In Override mode, provides an override state input that determines if the
override is to run or stop the drive (default = stop), and, if the drive is to
run, an override speed reference and direction.
