Motor Adjustments

SUMMARY

On some products or for unique customer solutions it may be necessary to set some features/parameters of the motor via a file.  Loading and setting via file import method keeps the admin features of the 5000 series hidden.

NOTE:  This is an internal document and should not be shared with customers.  The Import process can be shared with customers.

SOLUTION

Details

These features are available via the CSTM_MICROSTP define in the SystemIfo.h.  This define has been set for most products.

Once the CSTM_MICROSTP define has been set via code the MICROSTEP_RESOLUTION define will reflect whatever _stepMicrostepping has been set to via the imported MOTOR.CAL file.  The _stepMicrostepping variable will default to 256 if not set or not within range.

The micro stepping value is stored in the equipment's EEPROM.

All systems will default to a micro stepping value of 256 unless a custom MOTOR.CAL file is loaded.  The system will recognize the MOTOR.CAL file name in the following formats:

• MOTOR.CAL
• motor.CAL
• Motor.CAL
• The extension should be capitalized (.CAL).

The current Micro Stepping value can be viewed in the system information screen of the logger.

Files where micro stepping options are used:

Calibrations.c/.h, EEPROM.c/.h, Main.c, Stepper.c/.h, SystemInfo.h, and systempreferences.h.

MOTOR.CAL Format and Accepted Values

Line 1 of MOTOR.CAL file:

VALUE1 VALUE2 VALUE3

VALUE1 = Stepper Orientation [0 or 1 where 0 = Standard direction and 1 = Reversed direction]

VALUE2 = Gear Box Ratio Select [0 to 4 where 0 = 60.0, 1 = 61.45, 2 = 65.76, 3 = 71.53, and 4 = 73.0]

VALUE3 = Stepper Micro Stepping [8, 64, 128, or 256]

Example:

0 0 256

This will set a standard direction, a gear box ratio of 60, and a micro stepping resolution of 256.

Importing MOTOR.CAL

1. From the main screen of the logger select the menu option at the top left.
2. Choose SYSTEM PREFERENCES from the drop down list.
3. Select CALIBRATIONS.
4. Insert USB stick with MOTOR.CAL file.
5. Select the IMPORT button.
6. Select the MOTOR.CAL file and then click the IMPORT button.
7. The parameters will be imported and stored.
