System Limits
The system limits reflect the maximums of both the motor and the board being used.
Voltage limit: Not used by the firmware provided with this Kit.
Current Limit: Refer to the Fault Condition and Current Limit discussion in section 8.
Speed Limit: Is set at the value given in the motor’s data sheet, or at a predetermined
speed set by the particular motor data file.
CAUTION
Not all motors may be able to run at the maximum speed defined by the Speed Limit
parameter. It should be regarded as an upper limit and not the motor’s expected
maximum speed.
Storing and Using Setting Profiles
Once the parameters for a particular motor are established, it would be nice to preserve
them for future use. Users have several options from the Setup display to do just that.
Clicking on the Save button allows the current settings to be stored in a file, while clicking
on the Load button selects and loads a file with saved settings. Both commands used the
conventional Windows dialogs for opening and saving files. Setting profiles are saved as
motor data files (.mcd extension). Neither of these affects the parameters currently in
effect in the on-board firmware.
The Default button replaces all of the current settings with the default settings associated
with the current motor type. This may be useful for quickly starting over when a set of
parameters has been extensively modified and isn’t working.
The Download button transfers the currently displayed parameters to the on-board
firmware. It only changes the parameters, and not the control firmware itself.
Note 1: Attempting to load a motor data file that does not match the currently loaded motor
and/or control method type will generate an error message.
2: Remember that downloading a profile to the IRADK31 Controller board only
downloads variable values. It does not download new firmware. Similarly, loading
and saving profiles only loads or saves the motor data file to the computer, but does
not load or save the file on the on-board firmware.
