PowerFlex 753 Drive (P_PF753)
PowerFlex 753 Drive Output Structure
Output parameters include the following:
•
Output data elements (Out_) are the primary outputs of the instruction,
typically used by hardware output modules; however, they can be used by
other application logic.
•
Value data elements (Val_) are numeric outputs of the instruction for use
by the HMI. Values can also be used by other application logic or software
packages.
•
Source and Quality data elements (SrcQ_) are outputs of the instruction
used by the HMI to indicate PV source and quality.
•
Status data elements (Sts_) are bit outputs of the instruction for use by the
HMI. Status bits can also be used by other application logic.
•
Error data elements (Err_) are outputs of the instruction that indicate a
particular configuration error. If any Err_ bit is set then the Sts_Err
configuration error summary status is set and the Invalid Configuration
indicator is displayed on the HMI.
•
Not Ready data elements (Nrdy_) are bit outputs of the instruction for use
by the HMI for displaying the Device Not Ready indicator.
•
Alarm data elements (Alm_) are outputs of the instruction that indicate a
particular alarm has occurred.
•
Acknowledge data elements (Ack_) are outputs of the instruction that
indicate the corresponding alarm has been acknowledged.
•
Ready data elements (Rdy_) are bit outputs of the instruction used by the
HMI to enable or disable Command buttons and Setting entry fields.

Val_SpeedFdbk
REAL
Speed Feedback (actual) from drive.
Val_SpeedRefSrc
DINT
Speed Reference Source (enumeration)
1 = Reference A
2 = Reference B
3 = Preset 3
4 = Preset 4
5 = Preset 5
6 = Preset 6
7 = Preset 7
16…31 = Manual Reference Settings
Val_SpeedRefRaw
REAL
Copy of Speed Reference Output (in Raw units) for faceplate.
Val_SpeedFdbkRaw
REAL
Copy of Speed Feedback Input (in Raw units) for faceplate.
Val_SpeedRefEUMin
