Set an electronic gear numerator. (Refer to section 7.3.1.)
To enable the parameter values in the positioning mode, cycle the power after
setting.
To enable the parameter, select "Electronic gear (0 _ _ _)", "J3 electronic gear
setting value compatibility mode (2 _ _ _)", of "Electronic gear selection" in [Pr.
PA21].
Set the electronic gear within the following range. Setting out of the range will trigger
[AL. 37 Parameter error].

Set the number of gear teeth on machine side. (Refer to section 7.3.2.)
To enable the parameter values in the positioning mode, cycle the power after
setting.
Set the electronic gear within the following range.
(1) 1 ≤ CMX ≤ 16384, 1 ≤ CDV ≤ 16384
(2) ≤ ≤ 9999
(3) CDV × STN ≤ 32767 (STN: Number of stations per rotation [Pr. PT28])
(4) CMX × CDV ≤ 100000
Setting out of the range will trigger [AL. 37 Parameter error].
When a small value is set to the electronic gear ratio with the manual operation
mode, the servo motor may not drive at the set servo motor speed.
