7.2. Command Entry
l
Refer to “4.4. Handy Terminal” for the function of the keys.
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 0.5
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 the 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 power of the Driver Unit, make sure that a colon ( : ) is displayed.
If not, an alarm “Memory error” might be detected when you turn on the power
next time.
7.2.1. 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 “12. Command and Parameter” for details.
l
A command that requires the password may only be executed immediately after it is entered.
