7.2. Command Entry
l
Communication command shall consist of “a command (character string) + data (if necessary) +
ENT ”
l
If the velocity gain is to be set to 0.5, for example, “VG0.5” should be entered by adding data of
0.5G to a VG command.
l
Every time a character is input, the Driver Unit echoes the character back to the terminal. (The
Driver Unit returns same character it receives.)
l
When ENT code is input, the Driver Unit decodes a character string which it has received
(VG0.5 in the example above) and executes it. Therefore, a command is not executed unless it
ends with ENT .
！
Caution : When turn off the Driver Unit power, make sure that a colon ( : ) is
displayed. If not, an alarm “Memory error” might be detected when you
turn on the power next time.
7.3. Password
l
Among the communication commands used for this System, some special commands (such as
AB, PA, SI, etc.) require password entry for preventing erroneous entries. These commands
cannot be entered in the same manner as other commands.
l
The password is /NSK ON (a space between K and O) as shown below. If the Driver Unit
accepts it, it returns an “NSK ON” message. Refer to “11. Command and Parameter” for details.
l
A command requiring password entry may only be executed immediately after the password is
entered.
