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.
