parameter holding the upper 16-bits. The default Menu Word Swap is MSW-LSW.
Example: MSW-LSW
If var.var0 = 10 and is assigned to menu 18.11, it will actually reside in menu’s 18.11 and 18.12, 18.11 = 10 and 18.12 = 0.
Word Swap is used in EZMotion to change the order of the menu parameters.
Example: LSW - MSW
If var.var0 = 10 and is assigned to menu 18.11, it will actually reside in menu’s 18.11 and 18.12, 18.11 = 0 and 18.12 = 10.
Menu 18 - Menu 20
The user may select parameters to be interfaced to the following Unidrive SP and Digitax menu’s:
18.02-18.10 - 16-bit, Read Only
18.11-18.30 - 16-bit
19.02-19.10 - 16-bit, Read only
19.11-19.30 - 16-bit
20.01-20.20 - 16-bit
20.21-20.40 - 32-bit
If a 32-bit parameter is assigned to menu 18 or 19, that parameter will take two parameters with the higher parameter holding the
upper 16-bits. For example, if var.var0 is assigned to menu 18.11, it will actually reside in menu’s 18.11 and 18.12.
Both 16-bit and 32-bit parameters will take a single parameter for menu 20.
The parameters do not have a decimal place. But the complete value is passed. Consider the example where PosnCommand is
assigned to menu.20.30 and Position has four decimal places. If PosnCommand is equal to 12.8434, menu.20.30 will equal 128434.
For read/write parameters, the value can be changed by either the registry parameter being directly changed, or by the menu
parameter being changed. If Index.0.Dist is assigned to menu 20.21 and a program changes the value of Index.0.Dist to 12.8000,
menu.20.21 will equal 128000. If a user changes menu.20.21 to 136434, Index.0.Dist will then equal 13.6434. If a registry parameter
is read only, the menu parameter can read the value, but not change it.
The transfer between the registry and menu parameters is asynchronous and occurs a the same priority as a user program.
Menu 70
Menu 70 Setup is used to gain non-cyclic access to EZMotion parameters in the module. When the user drags an EZMotion
parameter from the left to the right PowerTools Pro gives the user the flexibility to assign a SP drive parameter number to the
EZMotion parameter. Using this newly assigned address the user may now access this EZMotion parameter using a PPO 4 word
configuration (see the SM-DeviceNet User Guide or SM-Profibus User Guide for more information), DeviceNet explicit messages
(see the SM-DeviceNet User Guide), Modbus RTU through the SM-Applications module, or Modbus TCP/IP (see the SM-Ethernet
User Guide). EZMotion parameters assigned a SP parameter number will NOT be accessible using Modbus RTU from the front of
the drive.
