3.2.2 Set Drive Parameters (in Velocity Loop Control Mode)
This operation is used to set parameters of the following servo drives in velocity
loop control mode:
• WISE servo drive
• YASKAWA Σ-7 servo drive
• Panasonic MINAS A5 servo drive
• Fuji ALPHA 5 servo drive
To reach rated rotational speed with 10V in velocity loop control mode, setting
parameters in velocity loop control mode differs from that in position loop control
mode in that:

3.3 Adjust Pulse Equivalent and Electronic Gear Ratio
This operation is used to adjust the control precision of the machine tool.
To adjust pulse equivalent and electronic gear ratio, do the following:
• To adjust pulse equivalent, set system parameter Pulse Equivalent in NcEditor
software.
• To adjust electronic gear ratio, set drive parameter Electronic Gear Ratio on
the drive.
For details of terms and calculation, see List of Terms and Calculation Formula.
3.3.1 List of Terms
This part introduces terms related to pulse equivalent and electronic gear ratio.
Pulse equivalent
The moving distance of the lead screw or rotation degree of rotary axis
corresponding to one pulse sent by CNC system, the minimum available distance
controlled by CNC system as well.
The smaller the pulse equivalent is, the higher the machining precision will be. The
larger, the faster feedrate will be.
