Understanding IMC-S/23x Setups

Editing the Direct
Command Mode
Configuration

After completing the axis fault action configuration, the IMC-S/23x
asks

Toggle to

YES

and press ENTER to configure direct command mode

for your application.

Direct Command Mode is a mode of operation where iCODE (the
native language of the IMC-S/23x) commands can be sent directly to
the IMC-S/23x via serial port A. It is used by the Online Manager in
GML for communicating with the motion controller during application
program development and debugging.

The recommended setting of the direct command mode configuration
parameters for use with GML is shown below:

If you are using a dumb terminal or other terminal emulation software
on a computer which automatically inserts Line Feed characters
whenever a Carriage Return character is received, answer

to the

Linefeed Insertion?

question to turn off the extra line feed

normally generated by the IMC-S/23x. You can tell that your terminal
is generating its own linefeeds if the direct command mode display is
double spaced.

Normally, the IMC-S/23x appends a Carriage Return character to the
response string generated by all commands sent to it in direct command
mode which request data. If you are using direct command mode to
communicate to a host computer, answer

to the

Carriage

Return Insertion?

question to turn off the sending of this

Carriage Return character after all response strings.

Normally, the IMC-S/23x echoes all commands sent to it in direct
command mode so that they are displayed on the screen. This is known
as full duplex operation. If you are using direct command mode to
communicate to a host computer or another IMC-S/23x in a multidrop
configuration, answer

HALF

to the

Duplex?

question to set the

IMC-S/23x direct command mode to half duplex and eliminate the extra
echoed characters.

Another Axis? NO

Edit Direct Command Mode Config? NO

Linefeed Insertion? YES
Carriage Return Insertion? YES
Duplex? FULL
Multidrop? NO

TIP: If the direct command mode display is double-spaced, turn off
Linefeed Insertion.
