Determine the movement amount and calculate value for the electronic gear setting by following
the formula below:
Linear Axis Unit Travel Distance: Min. Travel Distance Unit (1, 0.1, 0.01mm etc.) /pulse
Rotary Axis Unit Travel Distance: Min. Travel Distance Unit (1, 0.1, 0.01deg. etc.) /pulse
Electronic Gear Formula:
In the case of Linear Axis
In the case of Rotary Axis
Note 1 Refer to [9.4 List of Specifications of Connectable Actuators] for the encoder pulse of
each actuator.
