IV.4 Key control / LC display, Option -DISP-
When the -DISP- option is installed the parameters for the servo amplifier can still be set with
the aid of a PC, using the BS7200 operator software. In this case the -DISP- option is disabled.
When the supply voltage has been switched on, the status indication of the servo amplifier
appears in the display. The flashing star indicates the operational readiness of the micro-
processor. The type of controller is shown in the second line.
With the built-in -DISP- option the amplifier can be operated by digital key entry under operator
control, with a 2x16 character clear-text liquid-crystal display.
The servo amplifier can be operated by three keys:
IV.4.1 Key description / operation
The upper key is comparable to the ESCAPE and Cursor Up keys of a personal
computer. As you move around within the menu structure you can access the next higher menu
level by using this key. For numerical entries, a single short tap on the key will increase the
present value by 1. If you keep the key pressed down the value will be counted up, slowly at
first, then rapidly, up to the permitted maximum.
The middle key has the same function as the Cursor Down key in a personal computer.
You move down the menu with it, and when you have reached the last menu item it will jump to
the first one again. For numerical entries, a single short tap on the key will reduce the present
value by 1. If you keep the key pressed down the value will be counted down, slowly at first,
then rapidly, down to the permitted minimum.
The bottom key has a function which is similar to the ENTER key of a personal computer.
By operating this key you switch to the menu item which has been selected. If a parameter is
displayed, then this key will start the entry mode. After the parameter has been set you press
this key to transfer the value to the memory.
Moving round the menu
From the status display, you can use the middle key to access the first item in the menu.
With the key you can leave this menu level and get back to the status display.
For each menu item, you can use the key to access the first parameter which can be set
and, using key step through the parameter list. With you can jump back to the menu
level.
The next menu item is accessed by using the key.
Altering parameter values
When a parameter is displayed, use the entry key to access the entry mode. The parameter
will now appear with an underline. With the key or you can alter the value.
Using transfers the value to the memory.
Service functions
The service functions “CONSTANT SPEED” and “CONSTANT CURRENT” are active after
the corresponding parameter value has been entered, as long as is kept pressed.
The service function “REVERSING MODE” is activated as soon as you are in entry mode for
this service function. You are now able to optimize the servo amplifier (all the parameters which
can be set on-line) during reversing operation, so long as you do not leave the menu level. As
soon as you leave the menu, reversing mode is terminated and the status is displayed .
