6 SCL Test & Monitor
6.1 SCL Test
The
SCL
(Serial Command Language)
Test
tool is used to send commands to the serial port
of the connected drive. A command can be entered manually in the
Command
window at the
bottom of the screen. The history of the sent command and responses of the drive are displayed
in the
Command History & Response
window. This tool is designed to help the user learn SCL
usage prior to implementation on the system controller. The command interface allows entry of all
supported SCL commands. Any command syntax errors that are encountered are also displayed
in the response window. The Command History & Response window also displays commands and
responses used when operating the other functions provided on the SCL Test & Monitor tab such
as Jog Move or Single Move.
SSM Quick Tuner communicates to the connected drive using a high baud rate of 115200 and
a protocol that includes the Checksum. These protocol settings are used to provide high speed
and reliable communications with the drive during the configuration, tuning, or testing operations.
The response window will indicate the exact command syntax that is being used. This means that
the user will be able to see both the Checksum calculated for that command and the Checksum
provided in the response by the drive. This is a useful feature to help the system programmer
determine the proper Checksum calculation in the system controller. An option that is not
recommended is to check the
Hide Checksum
box (turns off the Checksum). A user might also
select hiding the Checksum so that it is not visible in the Command History & Response window.
6.2 Motion Status
The
Motion Status
tool provides the most common information needed about the moving or
position status of the drive. Four parameters are displayed that will show the
Command Position
,
Actual Position
,
Position Error
and the
Actual Speed
. Although the drive is being constantly
polled for this status information, the information is not real time as there is a slight delay in the
polling routine.
The
Clear Position
button is provided to clear the position information and set it to zero. The
position can only be cleared when the motor is not moving.
