Frequency converter with text editor
First Claim
1. A method for obtaining a symbol string user input via a four-directional control device in a frequency converter, wherein the four-directional control device is configured to receive user inputs associated with a first direction, a second direction perpendicular to the first direction, a third direction opposite to the first direction, and a fourth direction opposite to the second direction, the method comprising:
- grouping potential symbols into at least two symbol lists;
treating one of the symbol lists as a current symbol list;
displaying at least part of at least the current symbol list;
displaying a cursor indicating one of the symbols in the current symbol list as a current symbol;
receiving commands via the four-directional control device;
based on the received commands, selectively changing the current symbol list to one of the other symbol lists, effecting relative movement between the cursor and the current symbol list, and selecting the current symbol as the next symbol in the symbol string;
providing each of the symbol lists with a switch lists symbol;
receiving via the four-directional control device a user input associated with the first direction;
in response to receiving the user input associated with the first direction, moving the current symbol list in the third direction such that the cursor moves in the first direction relative to the current symbol list;
receiving via the four-directional control device a user input associated with the third direction;
in response to receiving the user input associated with the third direction, moving the current symbol list in the first direction such that the cursor moves in the third direction relative to the current symbol list;
receiving via the four-directional control device a user input associated with the second direction, when the cursor indicates a symbol other than one of the switch lists symbols;
in response to receiving the user input associated with the second direction, when the cursor indicates a symbol other than one of the switch lists symbols, selecting the current symbol as the next symbol in the symbol string;
receiving via the four-directional control device a user input associated with one of the second direction and the fourth direction, when the cursor indicates one of the switch lists symbols; and
in response to receiving the user input associated with the one of the second direction and the fourth direction, when the cursor indicates one of the switch lists symbols, changing the symbol list to one of the other symbol lists.

Abstract
A frequency converter includes a symbol string editor in which the potential input symbols are grouped into at least two symbol lists. One of the lists is treated as a current symbol list, which can be scrolled and from which the symbols can be selected as the user input. In addition, a user is allowed to control change of the current symbol list such that the symbols in all of the symbol lists are available for selection. This arrangement allows for scrollable lists to be significantly shorter than a single list of potential symbols would be, which makes entering symbol strings faster.
