12 Migration Guide
This chapter outlines some of the major differences between the UD70 product for
Unidrive Classic and the SM-Applications Modules & Motion Processors for Unidrive SP
that may be helpful in converting (porting) user DPL programs.
12.1 Drive Parameter Differences
The Unidrive SP parameter set has quite a few differences compared to the Unidrive
Classic. All parameters accessed in a DPL program should ideally have been
configured as #Define’s at the top of the program, thereby making conversions easier.
So in porting, you will have to go through the program by hand and locate all drive
parameter references. The first step is to search for the # symbol, and then go through
the program looking for any function blocks that may take parameter pointer inputs (e.g.
PFixRead or WRNET).
When parameters are located, make sure they are the same in the Unidrive SP and
ensure that they are in the same units. Adjust the parameter number or scaling as
appropriate.
12.2 UD70 Parameters
12.2.1 Setup Parameters
The set-up parameters can now be located in menu 15,16 or 17 whereas with UD70
they were always located in menu 17. It is strongly advised that new user DPL programs
that change setup parameters are altered to use menu 81 which will eliminate the need
to determine which of menu 15/16/17 is being used.
The table below outlines some of the major differences between the two setup menus:
Table 12-1 Setup Parameter Changes
Parameter Description Changes
Pr 17.03 Line number of error This is now Pr 81.48.
Pr
17.06 EIA-RS485 mode
Modes 2,3,4,9,10,11,12 are no longer supported.
The user modes 6,7,8 are not supported with the
current version of software.
Pr
17.08 EIA-RS485 pointer Not supported. Parameter is now turnaround delay
Pr
17.09 EIA-RS485 pointer 2 Not supported. Parameter is now TX enable delay
Pr
17.10 EIA-RS485 scale factor Not supported. Parameter is now DPL print routing
Pr
17.11 Clock tick time
With drive version < 01.05.00 the default is zero.
With drive versions >=01.05.00 the default is 10ms.
Pr
17.12 Position controller
This parameter now controls the scheduling rate for
the new POS0/1 which are different to those of
UD70 Speed and Encoder tasks.
Pr
17.15 EIA-RS485 trip mode
This parameter now allows the user to specify
whether an SM-Applications Modules & Motion
Processors module will reset upon resetting the
Unidrive SP from a trip condition..
Pr
17.16 IO Link sync. source
IO link is not supported. Parameter is now used to
select the encoder update rate.
Pr
17.20 Flash power-down store This parameter now takes immediate effect.
Pr
17.21 Disable MD29MON This parameter now controls the saving of menu 20.
Pr
17.22 RS232 drive-drive
Not supported. Parameter now defines CTNet token
ring ID.
