I ended up going with a brand new parker direct replacement.
What reminded me to come back and update is, I had the pleasure of troubleshooting and spec'ing the replacement of an Emerson/Control Techniques VS3 drive yesterday and it ripped off old scabs. There is no modified parameters menu. And no comms port on the drive. If you're not going to put a comms port on a drive then it should have a modified parameters menu. It should have that menu regardless, but especially if no comms port. How do I know the particulars of the application to spec a replacement? Or even if I want to direct replace with the same p/n? I must go through each and every parameter one at a time, comparing against the manual. That is ridiculous. It feels like a big middle finger from Emerson to me and everyone else who has to work on the things.
I've never heard of a CT drive model VS3????
There have been a few (short lived) low end models which didn't have a comms port (or option module available), but must have been 20+ years ago.
But anyway, there's a setting in Parameter MM.00 (any menu, parameter 0)
Parameter mm.000 (mm.000) value Action Possible failures
1000 Save drive user save parameters to non-volatile memory. Power-down save parameters are saved when the drive enters the under voltage state. No action if the drive is in the under voltage state
1001 Save drive parameters to non-volatile memory. It should be noted that power-down save parameters are also saved which will result in one background task scan being extended to 200ms.
1070 Reset all option modules
1233 Load 50Hz defaults No action if the drive is enabled
1234 Load 50Hz defaults to all menus except option module menus (i.e 15 to 20 and 24 to 28) No action if the drive is enabled
1244 Load 60Hz defaults No action if the drive is enabled
1245 Load 60Hz defaults to all menus except option module menus (i.e 15 to 20 and 24 to 28) No action if the drive is enabled
1299 Reset Stored HF trip.
2001 Create a boot file on a non-volatile media card based on the present drive parameters including all Menu 20 parameters Non-volatile media card trips
4xxx NV media card: Transfer the drive parameters to parameter file xxx Non-volatile media card trips
5xxx NV media card: Transfer the onboard user program to onboard user program file xxx Non-volatile media card trips
6xxx NV media card: Load the drive parameters from parameter file xxx or the onboard user program from onboard user program file xxx No action if the drive is enabled
Non-volatile media card trips
7xxx NV media card: Erase file xxx Non-volatile media card trips
8xxx NV Media card: Compare the data in the drive with file xxx Non-volatile media card trips
9555 NV media card: Clear the warning suppression flag Non-volatile media card trips
9666 NV media card: Set the warning suppression flag Non-volatile media card trips
9777 NV media card: Clear the read-only flag Non-volatile media card trips
9888 NV media card: Set the read-only flag Non-volatile media card trips
12000 Only display parameters that are different from their default value. This action does not require a drive reset.
12001 Only display parameters that are used to set-up destinations (i.e. DE format bit is 1). This action does not require a drive reset.
59999 Deletes an onboard user program if a program is present.
Note: Any parameter changes that have not been saved will be lost during this action. No action if the drive is enabled.
No action if there is no program present.
No action if the user program is enabled (i.e. Onboard User Program: Enable (11.047) = 1)
