3.7 Parameters to configure axis position reading and display.
The digits of digital parameters refer to the digits on the axis displays so digit
"1" (that can be changed with the [1] key) corresponds to the rightmost digit
and "8" to the leftmost digit.
XXXXXXXX <-- binary code
87654321 <-- keys
PARAMETER FUNCTION
PAR00 Feedback configuration, different per axis, binary type.
This parameter sets the specific characteristics of the feedback device (rotary
or linear encoder) used to read the axis position.
Digit
8, 7, 6 Not being used at this time (they must be set to "0")
5 Feedback resolution units:
Linear axis: 0 = mm, 1 = inches
Note: These units refer to feedback pulses not to the position display.
4 Type of axis: They must be set to zero.
3 Not being used at this time
2 Not being used; it must be set to "0".
1 Counting direction (0 = normal, 1 = reverse)
If an axis count increases or decreases in the opposite direction to the one
desired, change the value of this digit.
PAR01 Feedback resolution. Independent for each axis.
Possible values:
Linear axis:From 0.0001 mm up to 1.0000 mm (0.000005" to 0.03937")
Rotary axis:From 0.0001º to 1.0000º (from 1 to 999 seconds).
Factory setting: 0.0050 mm (5 µm).
Formula to calculate encoder resolution:
Where:
R = Resolution in degrees
p = Pulses per turn of the encoder
TTLfactor = Multiplying factor for TTL signal
Sfactor = Multiplying factor for sinusoidal signal
