Parameters Details
Set the electronic gear function.
The electronic gear can be used for the following:
• To set any value for the motor rotation and travel distance per input command.
Refer to "6-6 Electronic Gear Function (P.6-19)".
Electronic Gear Block Diagram:
The electronic gear ratio is set using the following equations.
If the Numerator = 0, the Numerator is automatically set to the encoder resolution. The number of
command input per rotation can be set by the Pn010.
If Numerator 0:
Set the limit values for the motor output torques (Pn013: No.1, Pn522: No.2).
Refer to the Torque Limit Selection (Pn521) for the torque limit selection.
During torque control, it limits the maximum torque in forward and reverse directions. The settings
on the Torque Limit Selection (Pn521) and the No.2 Torque Limit (Pn522) are ignored.
Set the value in units of 1% of the rated torque (100%).
E.g. When the maximum torque is limited to 150%.
