Section 2 – Modes of Operation 
2.1  Overview of Operating Modes 
 
The ESP300 can be operated in two basic modes: 
•  LOCAL mode 
•  REMOTE mode 
2.1.1 LOCAL Mode 
This mode is applicable only if your unit is equipped with the optional 
front panel display. If your ESP300 is equipped with the blank front 
panel, you may skip to the REMOTE Mode Section 3. 
In LOCAL Mode the user has access to a sub-set of the ESP300 
command set. In this Mode, the ESP300 is controlled by pressing the 
menu key and axis push-buttons on the front panel. 
Using this mode, the user can adjust motion parameters like velocity 
and acceleration without using a computer or terminal. 
NOTE 
See Section 2.2 for a detailed description of the front panel. 
 
2.1.2 REMOTE Mode  
In COMMAND Mode, the ESP300 receives motion commands 
through one of its interfaces (IEEE488 or RS232-C) using a computer 
or terminal. Additionally, an optional alphanumeric keypad with an 
LCD display enables the user to access the full command set of the 
ESP300 without the use of a computer interface (See Section 7.1.2). 
In this mode, the ESP300 employs a set of over 100 commands. 
Please refer to Section 3 (Remote Mode) for a detailed description of 
the ESP300 command set. 
In Program Execution Mode, internally stored programs are executed 
(See Section 3.1)
