Issue Number: 7 www.controltechniques.com
The drive Onboard PLC program status parameter indicates to the user the actual state of the drive Onboard PLC program. (not fitted / running /
stopped / tripped.)
The drive Onboard PLC programming events parameter holds the number of times a Onboard PLC program download has taken place and is 0 on
dispatch from the factory. If the drive Onboard PLC programming events is greater than the maximum value which may be represented by this
parameter the value will be clipped to the maximum value. This parameter is not altered when defaults are loaded.
The Onboard PLC program maximum scan time parameter gives the longest scan time within the last ten scans of the drive Onboard PLC program.
If the scan time is greater than the maximum value which may be represented by this parameter the value will be clipped to the maximum value.
The drive Onboard PLC program first run parameter is set for the duration of the first ladder diagram scan from the ladder diagram stopped state. This
enables the user to perform any required initialisation every time the ladder diagram is run. This parameter is set every time the ladder is stopped.
Value Description
0 Halt the drive Onboard PLC program.
1
Run the drive Onboard PLC program (if fitted). Any out-of-range parameter writes attempted will be clipped to the
maximum / minimum values valid for that parameter before being written.
2 Run the drive Onboard PLC program (if fitted). Any out-of-range parameter writes attempted will cause a drive trip.
