SMC
Is an acronym for Synchronous Motor Control, one of the control modes of the drive. This mode
computes the rotational speed similarly to open-loop vector control, and controls the field
reference or the synchronous motor as in closed-loop synchronous motor control.
SOP
(1) SOP is an acronym for Sum Of Products. The term "sum-of-products" comes from the
application of Boolean algebraic rules to produce a set of terms or conditions that are grouped
in a fashion that represents parallel paths (ORing) of required conditions that all must be met
(ANDing). This would be equivalent to branches of connected contacts on a relay logic ladder
that connect to a common relay coil. In fact, the notation can be used as a shortcut to describe
the ladder logic.
(2) SOP, when used as a filename extension, refers to System Operating Program.
SOP Utilities
The program within the Siemens Tool suite used for converting between text and machine
loadable code. It can also be used for uploading and downloading files over the RS232
connection.
See Tool Suite definition.
Speed Menu function
Speed menu is a feature of the menu system that allows the operator to directly access any
of the menus or parameters, rather than scrolling through menus to the appropriate item. This
feature uses the [Shift] button in conjunction with the right arrow. The user is prompted to enter
the four digit ID number associated with the desired menu or parameter.
Stop mode
Stop mode is used to shut down the drive in a controlled manner, regardless of its current
state.
Submenus
A submenu is one of four components found in the menu system. Submenus are nested menus
(i.e., menus within other menus). Submenus are used to logically group menu items based on
similar functionality or use.
Synchronous speed
Synchronous speed refers to the speed of an AC induction motor's rotating magnetic field. It
is determined by the frequency applied to the stator and the number of magnetic poles present
in each phase of the stator windings. Synchronous Speed equals 120 times the applied
Frequency (in Hz) divided by the number of poles per phase.
