1. Details of parameter
[Class 0] Basic setting
Title
Pr0.11 *
Range
You can set up the output pulse counts per one motor revolution for each OA and OB with
the Pr0.11 setup. Therefore the pulse output resolution after quadruple can be obtained from
the formula below.
The pulse output resolution per one revolution = Pr0.11 setup value × 4
Title
Pr5.03 *
Range
For an application where the number of output pulses per one motor revolution is not an
integer, set this parameter to a value other than 0; and the dividing ratio can be set by using
Pr0.11 as the numerator and Pr5.03 as the denominator.
Therefore the pulse output resolution after quadruple can be obtained from the formula below.
Pulse output resolution per one revolution
= (Pr0.11 setup value / Pr5.03 setup value) × Encoder resolution

* When Pr5.03 = 0, the above process is made according to
Pr0.11 setup value.
The number of pulses of reproduced pulse output OA and
0
OB are the number of pulses set in Pr0.11. The resolution of
pulse output per one revolution is equal to or less the encoder
resolution.
When the output source is external scale

* If Pr5.03 is not equal to 0, then the above process is performed
based on setup value of Pr0.11 and Pr5.03. This feature can be
1 to 262144 used for application where the number of reproduced pulses (OA,
OB) per one motor revolution is not an integer.
Note that when the number of pulses per one motor revolution
is not an integer, Z-phase output is not synchronized with that
of A-phase, reducing pulse width. The pulse output resolution
per one revolution cannot become higher than the encoder
resolution.
