Description
①
When number of setpoint pulses per motor revolution (p29011) is 0, configure electronic
gear ratio by setting numerator (p29012) and denominator (p29013).
②
When number of setpoint pulses per motor revolution is not 0, enter the number of set-
point pulses per motor revolution here.
③
Calculate the electronic gear ratio according to different mechanical structures.
Totally, five mechanical structures are available:
• Ball screw
• Disc table
• Belt pulley
• Rack and pinion
• Roll feed
For more information, see Section "Mechanical structure (Page 54)".
Enter the pitch value and gear ratio, select a display unit and click
. Then the
electronic gear ratio can be calculated automatically.
