Using the Self Tune function automatically tunes the current loop for the connected
motor. The five parameters tuned are as follows:
X***:IARM CONTIN - This parameter represents the percent motor current at
which continuous conduction of the current occurs.
X***:Z-C CORRECT - To fire the SCR's properly, the point at which the line
voltage crosses zero must be determined. Due to delays in
the sensing circuitry, an offset number must be entered.
X***:Z-C CORRECT is the value used to offset this delay.
X***:IARM PGAIN - These are the proportional and integral gain constants for
X***:IARM IGAIN the current loop. They determine how the current loop
reacts to disturbances.
X***:ARM RESIST - This is the value of the armature resistance in ohms.
