PA06 Set the number of gear teeth on machine side. (Refer to section 7.2.6.)
*CMX Set the electronic gear within the following range. Setting out of the range will trigger [AL.
37 Parameter error].

(3) CDV × STN ≤ 32767 (STN: Number of stations per rotation [Pr. PT28])
(4) CMX × CDV ≤ 100000
When a small value is set to the electronic gear ratio with the manual operation mode,
the servo motor may not operate at the set servo motor speed.
Travel distance of one station = Pt (servo motor resolution) ×
Setting range: 1 to 16777215
PA07 Set an electronic gear denominator. (Refer to section 7.2.6.)
*CDV Set the electronic gear within the range of [Pr. PA06].
Electronic Setting out of the range will trigger [AL. 37 Parameter error].

side
PA10 Set an in-position range per command pulse.
INP To change it to the servo motor encoder pulse unit, set [Pr. PC06].
In-position In the I/O mode, the in-position range is the range where Index 2D15h Status DO5 bit5
range (Travel completion) and Index 2D11h Status DO1 bit12 (In-position) are outputted.
The unit will be as follows depending on the positioning mode.

In the point table method
When [Pr. PC06] is set to "_ _ _ 0", the unit can be changed to [μm], 10
[pulse] with the setting of [Pr. PT01]. When [Pr. PC06] is set to "_ _ _ 1", the unit is
fixed to [pulse].
In the indexer method
It will be command unit [pulse]. (A load-side rotation expressed by the number of servo
motor resolution pulses)
For example, when making an in-position range "± 1 degree" for the rotation angle on
the load side, set 4194304 × (1/360) = 11650 pulses.
