6.4.4 Electronic gear ratio
Users could set different electronic gear ratios to enable the gearing to move different
distances. The relevant parameters are as below:

Incorrect E-Gear ratio setting will cause servo motor suddenly unintended acceleration, so
please ensure to set the parameter when servo is off. The E-Gear ratio setting value should
be within the range of 1/50 <(CMX/CDV) <64000, otherwise the motor may cannot operate.
The relationship between the E-Gear ratio numerator & denominator and the command is
showing in the figure below.
There are four groups of E-Gear ratio numerators for users to switch, please set 2 DI input
register as CM1 and CM2 before switching. Please refer to the following table for detail.
Name CM1 CM2 Control mode
E-Gear numerator 1 (PA06) 0 0 Pt
E-Gear numerator 2 (PC32) 1 0 Pt
E-Gear numerator 3 (PC33) 0 1 Pt
E-Gear numerator 4 (PC34) 1 1 Pt
◆ 0: CMx-SG is open-circuited,1: CMx-SG is short-circuited.
