SECTION 3: i PARAMETERS AND ALARM CODES
“i” Parameters.
The initialize, or set up parameters are used to tailor the operating characteristics of the control to
the system in which it is being used. The EAROM will save any parameter changes, regardless of power
shut down, provided the “s”ave, is entered. Don’t forget, you must be in the program terminal mode, with
the Manual/Remote switch set to manual.
i00 Set Following Error.
Factory setting, -250. This allows a maximum deflection of .25 before sending a “Pos Follow” error
alarm. {Changing this may cause your unit to not properly function. The factory setting is appropriate for
99.7% of all users needs}
i01 Set in Position Band.
Factory setting, 2. This is reflective to the motor/encoder accuracy and is preset to our motor
specifications. Do Not Change! Incorrect values will seriously damage the encoder and/or controller,
voiding your warranty.
i02 Set Home Direction.
One digit, “0” or “1”. Specifies direction in which home will take place. “0” is negative, and “1” is
positive direction.
i03 Set Home Offset.
Factory Set: 3000. During the homing operation, immediately after the encoder “C” channel is
detected, this parameter will cause the axis to make a move by the specified amount and direction. The
final position will be interpreted as the axis “zero” position. For homing instructions, please see “G28” and
“M-Z” instructions.
i04 Set Home Feedrate.
Three digits, where NNN is 0 to 999 and represents the % of maximum feedrate, of “i06”, the axis
will be moving, during the homing operation. An i04 value of 500 would be 50%, such as a value of 250
would be 25%, of the maximum value, set in i06.
i05 Set Backlash Compensation.
Five digits, based on encoder lines, and specifies the direction in which, and the number of
encoder lines the axis will overshoot the desired position, and return. Approaching position always from
the same direction, eliminates the effects mechanical looseness on positioning accuracy.
A “+” number causes the axis to overshoot position and return, when the axis motion is in the “-”
direction. A “-” number will cause the axis to overshoot, when the axis is in the “+” direction. The sign of
the backlash number indicates the direction, in which backlash take up will occur.
An i05 value of 1600 (72:1 G.R.), would overshoot by one degree, then return.
i06 Feedrate Set.
The maximum setting is 100,000 (60:1, 72:1 & 90:1) [90,000 on 180:1]which equals 100,000
[90,000] encoder counts per half second. This is the maximum amount of encoder counts, per half
second, that the CPU can count, without causing a fault This setting will not take effect, until the “F”
program feedrate is read. The “T” command generates its own feedrate, and is not affected by i06.
Please refer to the feedrate table for more information, on this subject.
i07 Set Servo Loop Gain Factor.
3 Digits, Gain Control, i07NNN.
Where NNN is 1 to 255 and controls the responsiveness of the servo loop in responding to a
position error. The larger the number the "racier" the servo loop becomes. This parameter, together with
-26-
