Command Scaling (Electronic Gear)
This function multiplies a pulse command value input from the controller by the specified scaling factor to use as a posi-
tion command to the position control section. Using this function allows arbitrary setting of the motor revolution and dis-
tance per unit input command pulse and increase of a command pulse frequency when the required motor speed cannot be
obtained due to the limit to the controller pulse output capability.

pulse
Specifies the command pulse count corresponding to one revolution
of the motor.
When this setting is 0, Pr0.09 "1st numerator of electronic gear" and
Pr0.10 "Denominator of electronic gear" are valid.
This setting is invalid in full-closed control.

Specifies the numerator for scaling for a command pulse input.
Valid when Pr0.08 "Command pulse counts per one motor revolution"
is 0 or in full-closed control.
When this parameter is set to 0, the encoder resolution is set to the
numerator for position control, and for full-closed control, the
command scaling ratio becomes 1:1.
