13.3.2 Electronic gear function
The "electronic gear function" adjusts the actual machine movement amount and
number of pulse output to servo amplifier according to the parameters set in the
Simple Motion module.
The "electronic gear function" has the following three functions ( [A] to [C] ).
[A] During machine movement, the function increments in the Simple Motion
module values less than one pulse that could not be output, and outputs the
incremented amount when the total incremented value reached one pulse or
more.
[B] When machine OPR is completed, current value changing is completed,
speed control is started (except when current feed value is updated), or fixed-
feed control is started, the function clears to "0" the cumulative values of less
than one pulse which could not be output. (If the cumulative value is cleared,
an error will occur by a cleared amount in the feed machine value. Control
can be constantly carried out at the same machine movement amount, even
when the fixed-feed control is continued.)
[C] The function compensates the mechanical system error of the command
movement amount and actual movement amount by adjusting the "electronic
gear".
(The "movement amount per pulse" value is defined by "
Pr.2
Number of pulses
per rotation (AP)
", "
Pr.3
Movement amount per rotation (AL)
" and "
Pr.4
Unit
magnification (AM)
".)
The Simple Motion module automatically carries out the processing for [A] and [B].
The details shown below explain about the "electronic gear function", including the
method for compensating the error in [C] above, etc.
