Supplementary 1: Setting the number of position pulses
For a separate detector with a fine resolution, the number of position
feedback pulses may exceed 13100 even when initialization bit 0 is set
to 1. In such cases, use the position feedback pulse conversion
coefficient.
Suppose:
Number of position feedback pulses = A × B
Select B so that A is within 32767. Then, set the following:
A: Number of position feedback pulses set in the parameter
(less than or equal to 32767)
B: Conversion coefficient for the number of position feedback
pulses
2628

When the servo software series/edition used does not support this
function, make modifications listed below to prevent invalid parameter
setting alarms.

Current number of position pulses/E < 13100
