7 - 18
PA06 *CMX 1 1–16777215 CP CL
Electronic gear numerator (command pulse multiplication numerator)
Set an electronic gear numerator. (Refer to the instruction manual.)
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)”, or
J2S electronic gear setting value compatibility mode (3)” of “Electronic gear selection” in parameter PA21.
Set the electronic gear within the following range. Setting out of the range will trigger AL. 37 (Parameter error).
Parameter PA21 Electronic gear setting range
0 (1/865) < (CMX/CDV) < 271471
2 (1/13825) < (CMX/CDV) < 16967
