Host Command Reference
The Q Programmer software automates many of the functions shown in the diagram above.
SCL Utility software
The SCL Utility software is an excellent application for familiarizing yourself with host commands. SCL Utility
can be downloaded for free from www.applied-motion.com.
To send commands to your drive from SCL Utility simply type a command in the Command Line and press
the ENTER key to send it. (Remember that all commands are capital letters so pressing the Caps Lock key first
is a good tip). Pressing the ENTER key while in SCL Utility does two things: it terminates the command with a
carriage return and automatically sends the entire string. Try the example sequence below. In this example, note
that <ENTER> means press the ENTER key on your keyboard, which is the same as terminating the command
with a carriage return.
IMPORTANT: We recommend practicing with SCL commands with no load attached to the motor
shaft. You want the motor shaft to spin freely during startup to avoid damaging mechanical components
in your system.
AC25<ENTER> Set accel rate to 25 rev/sec/sec.
DE25<ENTER> Set decel rate to 25 rev/sec/sec
VE5<ENTER> Set velocity to 5 rev/sec
FL20000<ENTER> Move the motor 20000 steps in the CW direction.
If your motor didn’t move after sending the FL20000 check the LEDs on your drive to see if there is an error
present. If so send the AR command (AR<ENTER>) to clear the alarm. If after clearing the alarm you see a solid
green LED it means the drive is disabled. Enable the drive by sending the ME command (ME<ENTER>) and
verify that the you see a steady, flashing green LED. Then try the above sequence again.
Here is another sample sequence you can try.
JA10<ENTER>
Set jog accel rate to 10 rev/sec/sec
JL10<ENTER> Set jog decel rate to 10 rev/sec/sec
JS1<ENTER> Set jog speed to 1 rev/sec
CJ<ENTER> Commence jogging
CS-1<ENTER> Change jog speed to 1 rev/sec in CCW direction
SJ<ENTER> Stop jogging
In the above sequence notice that the motor ramps to the new speed set by CS. This ramp is affected by
the JA and JL commands. Try the same sequence above with different JA, JL, JS, and CS values to see how the
motion of the motor shaft is affected.
