Command Scaling (Electronic Gear) - Panasonic Minas-LIQI Series Technical Reference

4－2－2 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.
